Top Cryptographic Inventory Vendors and Methodologies

Cryptography has quietly become the largest ungoverned attack surface in the enterprise. It is embedded in source code, libraries, network protocols, certificates, configuration files, firmware, cloud key stores, secrets vaults, HSMs, databases, and dozens of other places that no single team fully owns. For years, this distributed footprint did not matter much because the underlying algorithms were considered safe, and certificate lifecycles were measured in years. That world is over. 

Three structural shifts are converging at once. The CA/Browser Forum is moving toward 47-day TLS certificate lifespans by 2027. NIST and PCI-DSS expectations around cryptographic inventory are tightening. And NIST’s finalized post-quantum standards (FIPS 203, 204, and 205) put every RSA and ECC deployment on a migration clock, with federal agencies required to migrate by 2035. Gartner estimates that through 2027, more than 60% of organizations will fail a compliance audit due to untracked cryptographic assets. 

Answering “where exactly is your cryptography and is any of it broken?” is the job of a cryptographic inventory. A good inventory tells you what algorithms you use, where they live, who depends on them, and which ones expose you to risk. It is the foundation for crypto-agility, post-quantum migration, compliance reporting, and incident response. The market for tools that build this inventory has matured rapidly, with approaches ranging from passive network sniffing to agent-based host scanning, static code analysis, and AI-driven correlation across the full estate. 

This blog walks through the leading cryptographic inventory vendors and the methodologies they use, starting with Encryption Consulting’s CBOM Secure, the platform we believe sets the bar for what an enterprise-grade discovery, inventory, and governance solution should look like in 2026 and beyond. We then cover the other notable products in the space: their primary discovery approach, their strengths, their limitations, and the use cases each one fits best. 

What Is a Cryptographic Inventory Tool? 

A cryptographic inventory tool discovers, catalogs, and continuously monitors every cryptographic asset an organization uses. That includes algorithms (RSA, ECC, AES, SHA, and post-quantum candidates such as ML-KEM, ML-DSA, and SLH-DSA), encryption keys, digital certificates, libraries, protocols, and the systems and applications that depend on them. The output is typically a Cryptography Bill of Materials, or CBOM, often expressed in the open CycloneDX 1.6 standard, which can be queried, reported on, and fed into downstream remediation, GRC, and supply-chain workflows. 

Inventory tools differ in how they find cryptography. The five common discovery methods are: 

• Static code analysis — scanning source code or compiled binaries for cryptographic API calls, library usage, and embedded secrets. 
• Passive network monitoring — sniffing traffic on a tap or SPAN port to identify protocols, ciphers, and certificates in transit. 
• Agent-based host scanning — deploying sensors on endpoints to inspect file systems, certificate stores, configurations, and runtime behavior. 
• Configuration and dependency analysis — examining application configs, package manifests, key stores, and infrastructure-as-code to find weak ciphers and outdated libraries. 
• Cloud and KMS API integration — pulling metadata directly from cloud key services, HSMs, vaults, and KMIP-managed systems. 

No single technique covers everything. A serious cryptographic inventory program needs a combination of methods, ideally on a single platform that correlates findings rather than leaving teams to stitch together exports from multiple point tools. 

Why a Cryptographic Inventory Matters in 2026?

The pain is no longer abstract; it is measurable, costly, and for most enterprises it is getting worse every quarter: 

• Cryptographic sprawl — most enterprises have tens of thousands of keys and certificates scattered across cloud, on-prem, HSMs, databases, secrets vaults, and source code, with no authoritative inventory. 
• Unplanned outages from expired certificates — a single expired certificate on a critical service can cost $100K to $1M+ per hour. The 2020 Microsoft Teams outage, the 2021 Google Voice outage, and repeated Fortune 500 incidents all trace back to a single certificate no one owned. 
• Silent security gaps — weak or deprecated algorithms (SHA-1, RSA-1024, MD5, 3DES) continue to run in production environments years after being deprecated, creating audit findings and active exploitation risk. 
• Failed or costly compliance audits — preparing a cryptographic inventory manually for SOC 2, PCI-DSS, HIPAA, or FedRAMP typically consumes four to eight weeks of analyst effort per audit cycle, and reconstructed evidence is frequently rejected by auditors. 
• Inability to plan a quantum-safe migration — NIST finalized post-quantum standards in August 2024, but most enterprises still lack a clear inventory of their quantum-vulnerable assets to begin from. 
• Slow incident response — when a CA is compromised (DigiNotar, Symantec distrust) or an algorithm is broken, identifying the blast radius manually takes days to weeks. 
• Insecure cryptography introduced in source code — hardcoded secrets, deprecated library usage, and embedded credentials shipped into production cost roughly 100x more to remediate post-deployment than at code review. 
• Fragmented tooling — security teams manually reconcile inventories across Azure Key Vault, Google Cloud KMS, AWS KMS, HSMs, HashiCorp Vault, and on-prem systems, a process that is brittle, expensive, and always out of date. 

Top Cryptographic Inventory Tools in 2026 

The cryptographic inventory market in 2026 spans a broad spectrum of approaches, from network probes and host-based agents to static code analyzers, cloud-native KMS connectors, and unified governance platforms that bring it all together. Each tool reflects a different philosophy about where cryptography hides and how best to find it. The vendors below are the platforms most frequently shortlisted by enterprise security teams preparing for post-quantum migration, 47-day certificate lifecycles, and the next wave of compliance mandates.

We start with Encryption Consulting’s CBOM Secure, the platform purpose-built to deliver every layer of cryptographic visibility on a single pane of glass, and then walk through the other notable products in the space, the methodologies they rely on, and the situations each one fits best.

Encryption Consulting’s CBOM Secure 

CBOM Secure is Encryption Consulting’s enterprise Cryptography Bill of Materials platform, designed from day one to be the system of record and continuous intelligence layer for enterprise cryptography. It automatically discovers, inventories, and continuously monitors every encryption key, digital certificate, and cryptographic algorithm across cloud platforms, on-premises servers, Hardware Security Modules, databases, secrets vaults, and application source code, scoring each asset for risk, evaluating it against compliance policies, and mapping exposure to the coming quantum threat, all on a single platform. 

CBOM Secure was engineered to be a single source of truth for enterprise cryptography, with the breadth, depth, and rigor that programs facing post-quantum migration, 47-day certificate lifecycles, and continuous compliance actually require. 

What Sets CBOM Secure Apart 

• Widest discovery footprint on a single platform — CBOM Secure performs automated, parallel discovery across cloud KMS (Azure Key Vault, Google Cloud KMS, AWS KMS), HashiCorp Vault, KMIP-managed systems, HSMs, directory services, databases, application binaries, key stores (Java JKS, PKCS12, BKS), file systems, network services, web services, secrets vaults, keyrings, native cryptographic APIs (PKCS#11, CNG), and application source code. 
• Source code cryptography scanning — CBOM Secure analyzes cryptographic API and library calls inside application code to produce a complete map of which algorithms, key sizes, and protocols each service depends on. This is foundational for the post-quantum transition and, as a secondary benefit, catches hardcoded secrets, deprecated algorithms, and embedded credentials at code review, where remediation is roughly 100x cheaper than fixing them in production. 
• Relationship-graph modeling and impact analysis — cryptographic assets are modeled as a dependency graph, not a flat list. Certificates are linked to their private keys, secrets are traced to the services that consume them, and dependencies are followed across systems. When a CA is compromised or a CVE drops, blast radius is identified in minutes. 
• Cryptography-aware risk scoring (0–100, Safe → Critical) — the engine factors algorithm weakness, expiry proximity, key reuse, key size, self-signed certificates in production, insecure cipher configurations, and per-system risk concentration. Analysts focus on Critical and High findings on day one rather than triaging thousands of assets by hand. 
• Quantum-readiness as a first-class capability — quantum awareness is built in from day one, not bolted on later. CBOM Secure tracks quantum-vulnerable algorithm exposure, monitors quantum-safe adoption against NIST FIPS 203/204/205 standards, and produces a data-driven, system-by-system PQC migration roadmap. 
• Continuous compliance evaluation — every asset is evaluated against NIST, PCI-DSS, FIPS 140-3, CMMC 2.0, CNSA 2.0, ISO 27001, SOC 2, HIPAA, FedRAMP, customer-defined and many international standard policies, with instant violation visibility and audit-ready reports on demand. Audit preparation effort drops by 70–80%, and compliance posture is always current rather than reconstructed under pressure. 
• Open-standard CycloneDX exports — the CBOM is emitted in the open CycloneDX industry format, with native interoperability with SBOM, GRC, and supply-chain tooling. No vendor lock-in. 
• Self-protecting platform — CBOM Secure encrypts and tags its own sensitive metadata, so the inventory platform itself meets the same standards it enforces, rather than becoming the weakest link in the governance program it is meant to support. 
• Modular plug-in architecture — new discovery sources can be added without core platform changes, so customers with proprietary or custom infrastructure can extend coverage without vendor-side engineering. 
• Native multi-organization, multi-tenant design — a single deployment supports fully isolated tenants, suitable for large enterprises with multiple business units and for MSSPs delivering to multiple clients. New tenants are onboarded in hours rather than weeks. 
• Flexible, deployment-friendly architecture — CBOM Secure offers fully agentless discovery for cloud, network, vaults, and KMS, with a lightweight optional agent for environments that require deeper local scanning. It deploys cleanly in regulated, air-gapped, federal, defense, financial, and healthcare environments. 

Key Features and Benefits 

• Multi-layer cryptographic discovery — parallel scanning across cloud KMS, HSMs, databases, network services, file systems, secrets vaults, and source code produces a complete inventory in hours rather than weeks. 
• Unified, deduplicated inventory — algorithm, key size, location, ownership, expiry, relationships, and full change history are captured for every asset, replacing the conflicting spreadsheets and partial exports that security teams typically rely on. 
• Proactive alerts via email and Microsoft Teams — the right teams are notified about expiring certificates, policy violations, and risk-level changes before they escalate. Customers typically reduce certificate-related incidents by over 90% within the first 90 days. 
• Role-based, drag-and-drop dashboards — tailored views for CISOs, security analysts, compliance officers, and administrators, so each stakeholder sees exactly what they need without bespoke reporting work. 
• Tamper-evident, cryptographically verifiable audit trail — what changed, when, by whom, and from what prior state is captured in a record that cannot be altered. Defensible evidence for regulators, auditors, and forensic investigations is produced continuously rather than on request. 
• Active vs. dormant cryptography awareness — CBOM Secure distinguishes cryptography that exists in code from cryptography actually executed at runtime, so teams remediate exploitable exposure first instead of chasing theoretical references buried in unused dependencies. 

Business Outcomes 

• A complete cryptographic inventory in hours instead of the weeks or months required by manual or fragmented approaches. 
• Over 90% reduction in certificate-related incidents within the first 90 days. 
• 70–80% reduction in audit-preparation effort, with continuous, audit-ready evidence. 
• Incident response blast-radius identification in minutes instead of days or weeks. 
• Multiple point tools collapsed into a single platform, reducing tool spend and integration overhead. 
• A credible, data-driven post-quantum migration roadmap, sequenced on the customer’s timeline rather than in crisis mode. 

Use Cases for CBOM Secure 

• Post-quantum readiness and migration — enterprises preparing for the PQC transition use CBOM Secure to inventory every quantum-vulnerable algorithm, prioritize systems by exposure, and execute a phased, dependency-aware migration to NIST FIPS 203/204/205 standards. 
• Compliance and audit evidence — organizations under FIPS 140-3, CNSA 2.0, CMMC 2.0, NSM-10, PCI-DSS 4.0, HIPAA, FedRAMP, or ISO 27001 produce continuous, machine-verifiable proof of cryptographic posture. 
• Crypto-agility and certificate outage prevention — with shrinking certificate validity periods, CBOM Secure prevents expired-certificate outages and ensures no asset is ever caught using a weak or non-compliant certificate. 
• Shift-left source code cryptographic governance — DevSecOps and AppSec teams use CBOM Secure to catch insecure library usage, hardcoded secrets, and deprecated algorithms at code review rather than in production. 
• Supply chain and third-party cryptographic risk — cryptography embedded in third-party software, containers, and firmware is inventoried and tracked, exposing supply-chain risk that traditional SBOM tools miss. 
• Incident response and CA compromise — when a CVE drops or a CA is distrusted, security teams query CBOM Secure to identify every affected system in minutes. 
• MSSPs and consulting partners — multi-tenant architecture lets service providers deliver cryptographic posture management to multiple clients from a single deployment. 
• Mergers, acquisitions, and cloud migrations — organizations baseline the cryptographic footprint of acquired environments or newly migrated workloads before integrating them. 

Who Should Buy CBOM Secure 

The primary economic buyer is the Chief Information Security Officer or VP of Security, who owns cryptographic governance, audit posture, and quantum-readiness strategy. The platform is also sponsored by Application Security and DevSecOps leaders (for source code cryptography and shift-left enforcement), Cloud Security and Platform Security teams (for multi-cloud KMS, vault, and HSM coverage), and GRC and Compliance leaders (for continuous policy evaluation and audit-ready reporting). For MSSPs and consulting partners, the buyer is the service-delivery lead responsible for managing the multi-client cryptographic posture. 

Other Notable Cryptographic Inventory Tools 

The vendors listed below address parts of the cryptographic inventory problem, and many are recognized by frameworks such as NIST NCCoE. The descriptions that follow summarize each product’s primary discovery approach, the strengths it is most often credited with in the market, and the limitations practitioners typically encounter when deploying it. 

IBM Quantum Safe Explorer and CBOMkit 

IBM’s cryptographic inventory ecosystem is built around the Cryptography Bill of Materials concept that IBM contributed to the CycloneDX 1.6 specification. The suite includes IBM Quantum Safe Explorer, which performs static analysis of source and object code to locate cryptographic assets, dependencies, and vulnerabilities; IBM Quantum Safe Advisor, which builds a dynamic operational view by monitoring runtime elements like TLS cipher suites, certificates, and key usage; and IBM Quantum Safe Remediator, which lets teams deploy and test quantum-safe replacement patterns including hybrid encryption schemes and proxy gateways. IBM also open-sourced a CBOM toolkit (CBOMkit) through the Linux Foundation. 

Strengths 

• Broad language support and binary scanning across diverse application portfolios. 
• Risk-ranked inventory linking each cryptographic instance to business context and policy compliance. 
• End-to-end Discover, Assess, Remediate workflow with proven mitigation patterns, including the ability to introduce quantum-safe encryption via proxies without rewriting legacy code. 
• Significant contributor to open standards through the CycloneDX CBOM specification and CBOMkit. 

Limitations 

• Static scanner coverage is limited to supported languages and libraries; cryptography in unsupported frameworks or custom code can be overlooked. 
• Pure static analysis can miss runtime cryptographic choices loaded from configuration files or device settings, which is why Advisor is needed to fill the gap. 
• Enterprise-scale deployment requires significant expertise, tuning, and compute resources (IBM recommends robust hardware for large codebases). 
• The suite identifies and prioritizes issues but does not automate the actual cryptographic replacement; skilled personnel are still needed to execute fixes. 

Best Suited For 

Large enterprises and government agencies with huge application portfolios and complex supply chains, where IBM’s end-to-end suite can produce an actionable inventory and compliance view at scale. 

Keyfactor Crypto-Agility (InfoSec Global AgileSec) 

Following Keyfactor’s 2025 acquisition of InfoSec Global, the AgileSec Analytics platform is now part of Keyfactor’s offering. AgileSec is an agent-based, host-centric tool that deploys lightweight sensors on endpoints, or leverages existing agents like Tanium or CrowdStrike, to scan systems for cryptographic artifacts. It searches file systems, registries, and memory for keys and certificates, identifies cryptographic libraries and their versions, and inspects configurations and API calls on each machine. NIST’s NCCoE has validated this technology as part of its PQC migration initiative. 

Strengths 

• Deep visibility into how cryptography is actually implemented on servers and applications, including outdated libraries and weak keys in keystores. 
• Easier deployment in environments that already run supported EDR agents like CrowdStrike or Tanium. 
• Consolidated dashboard with rich reporting, risk scoring, and compliance checks against standards like NIST and PCI-DSS. 
• Continuous monitoring with policy enforcement (e.g., alerting on disallowed cipher use). 

Limitations 

• Endpoint scanning requires installing sensors or using existing agents, which may not be feasible on every device. Legacy systems, OT devices, or appliances that cannot support an agent become blind spots. 
• Strength is in IT environments; purely network devices or deeply embedded IoT may not be directly scanned. 
• It can find cryptographic items on a host but may not automatically reveal how they are used in custom application code. 

Best Suited For 

Enterprise IT environments that need a comprehensive inventory across a large fleet of servers, VMs, and endpoints, especially banks and similar organizations preparing for long-term crypto-agility. 

SandboxAQ AQtive Guard 

SandboxAQ, an Alphabet spin-off that also acquired Cryptosense, offers AQtive Guard as a multi-method 360-degree cryptography inventory platform. It combines three discovery modalities: a passive Network Analyzer that captures live traffic to identify protocols and ciphers in transit, an Application Analyzer that hooks into running processes to log calls to crypto libraries, and a Filesystem Analyzer that scans at-rest files and binaries. 

Strengths 

• Cross-layer visibility covering cryptography in code, on disk, and on the wire. 
• Runtime hooking can detect dynamically generated keys, and legacy cipher calls that static analysis would miss. 
• Strong policy enforcement against FIPS-140, PCI-DSS, and internal cryptographic policies, in both network and application contexts. 
• Proven scalability with deployments at the U.S. Air Force, Department of Health & Human Services, and global banks. 

Limitations 

• Multi-pronged deployment is more complex; instrumenting applications with the runtime Application Analyzer can introduce overhead or instability and may be discouraged in extremely sensitive production environments. 
• The Network Analyzer needs access to network taps or SPAN ports, which can be an infrastructure challenge. 
• Handling data from three sources requires mature data analysis capabilities. 
• Premium pricing makes it best suited to organizations willing to invest in a comprehensive platform. 

Best Suited For 

Large enterprises and government agencies that need the most complete cryptographic visibility across heterogeneous environments spanning multiple programming languages and a mix of on-prem and cloud. 

CryptoNext COMPASS 

CryptoNext Security, a Paris-based post-quantum startup, offers COMPASS, which pairs a high-performance passive network probe with an analytics platform. The probe sits on network taps or SPAN ports and parses over 100 IT and OT protocols automatically, extracting algorithms, key lengths, and certificate details from each session. It is completely passive, performing no handshakes and injecting no traffic, and stores findings in CBOM format. 

Strengths 

• Fully passive operation makes it ideal for sensitive environments where active scanning or new endpoint software is not acceptable. 
• Broad protocol coverage including HTTPS, SSH, VPN, industrial control system protocols, and IoT communication. 
• Focused output reports only cryptographic weakness rather than all network flows, reducing noise. 
• Simple deployment and scalable architecture, with real-time analysis up to roughly 1 Gbps and a roadmap toward 10 Gbps. 

Limitations 

• As a network-only tool, COMPASS sees only cryptography in transit. If an application uses encryption internally (e.g., encrypting a file on disk) the probe will not catch it. 
• Cannot decrypt content (unless provided keys in special cases); detection relies on handshake metadata. 
• Highly distributed networks or cloud environments may require multiple probes for full coverage. 

Best Suited For 

OT and IoT environments such as manufacturing, utilities, and healthcare devices where active scanning is unsafe, and as a continuous network compliance monitor in IT networks. 

Quantum Xchange CipherInsights 

CipherInsights, recently acquired by Keyfactor, is a passive network listener that continuously monitors traffic for cryptographic risk factors, including quantum-vulnerable algorithms, plaintext communications where encryption should be present, weak cipher suites, and expired or untrusted certificates. It was recognized by NIST’s NCCoE as a recommended discovery tool for PQC migration efforts and includes a dashboard that tracks an organization’s progress toward quantum-safe cryptography. 

Strengths 

• Real-time, continuous monitoring of cryptographic posture across all observed traffic, including outbound to the internet for shadow IT detection. 
• Focus on dozens of cryptographic risk factors produces actionable findings rather than raw data. 
• Zero network impact (fully passive) and easy drop-in deployment. 
• Quantum-safe progress dashboard makes it useful as a leadership and compliance management tool. 

Limitations 

• As a network-only solution, CipherInsights does not directly tell you where in a system an algorithm is implemented; you still need to investigate the server to fix it. 
• Encrypted traffic inside another tunnel (e.g., HTTPS inside a VPN) is not visible unless the probe is inside the tunnel termination point. 
• High-throughput links may produce large volumes of cryptographic events, requiring scale planning. 
• Post-acquisition, standalone availability may evolve as Keyfactor integrates the technology into a broader platform. 

Best Suited For 

Government agencies and financial institutions responding to mandates such as NSM-10 that require inventories of quantum-vulnerable cryptography, and as an ongoing compliance monitor in corporate settings. 

PQStation QVision 

PQStation, based in Singapore, offers QVision as an AI-driven platform for cryptographic risk assessment and inventory. It uses lightweight endpoint sensors and integrations with existing EDR or monitoring tools to gather cryptography data, then catalogs cryptographic objects enterprise-wide including SSL/TLS certificates, SSH keys, cryptographic libraries and algorithms in use, and hardcoded secrets where detectable. A correlation engine cross-references certificates with expiration dates, flags short key lengths, and detects key reuse. 

Strengths 

• Flexible deployment using either dedicated sensors or hooks into existing SIEM/EDR infrastructure. 
• Broad coverage spanning certificates, keys, algorithms in configurations and code, with correlation insight into where weak ciphers are used and which library versions share them. 
• Real-time policy monitoring keeps the environment compliant after initial cleanup. 
• Compliance reporting and attestation features translate raw inventory into management-level metrics for regulated industries. 

Limitations 

• Newer entrant; may not have the breadth of integrations or track record of longer-standing vendors. 
• Coverage of network appliances and closed systems depends on whether they can run a sensor or be queried. 
• AI-driven recommendations improve with data, so very unique or small environments may get less insight initially. 
• Positioned primarily for quantum risk; some traditional crypto management features (such as detailed key lifecycle management) may not be in scope. 

Best Suited For 

Mid-sized organizations in regulated sectors (banking, government, healthcare) that want a guided assessment-led approach to starting a post-quantum cryptographic inventory. 

QryptoCyber Platform 

QryptoCyber is an AI-powered cryptographic inventory and management platform organized around five pillars: External Network, Internal Network, IT/OT Assets, Databases, and Code. Rather than building dedicated scanners for each pillar, the platform orchestrates a combination of techniques and third-party tools to cover all areas, then funnels findings into an AI engine that produces a unified CBOM and risk-mitigation roadmap. 

Strengths 

• Five-pillar coverage avoids the blind spots of single-method tools, ensuring areas like database encryption and CI/CD pipeline crypto are not overlooked. 
• Flexible “your agent or ours” deployment that can use existing tools to reduce duplication and tool fatigue. 
• AI-driven analysis produces coherent leadership narratives instead of raw issue dumps. 
• Outputs in standard CBOM format with PQC readiness scores for stakeholder communication. 

Limitations 

• Inventory accuracy and depth depend on the underlying scanners and integrations; if an environment lacks existing scanning, QryptoCyber’s deployed collectors may not be as mature as specialized vendor solutions. 
• Newer company; some features (e.g., full automation of database scanning or special OT protocols) may still be evolving. 
• AI recommendations are only as good as the data, so unique cryptographic use cases may still need human expert validation. 

Best Suited For 

Enterprises embarking on quantum readiness as a structured program who want an end-to-end packaged solution, including organizations preparing for compliance frameworks like PCI DSS 4.0 that explicitly require crypto inventories. 

ISARA Advance 

ISARA, a Canadian PQC company, offers Advance as a cryptographic inventory and risk-assessment platform with an agentless architecture. Instead of installing its own scanners, Advance integrates with existing NDR and EDR tools to ingest the cryptographic data they already collect (for example, TLS handshake logs from a network detection system and certificate inventories from an endpoint security platform), then aggregates findings into a centralized dashboard. 

Strengths 

• Agentless design enables rapid deployment in environments with existing security telemetry, with no additional load on sensitive systems. 
• PQC-focused: surfaces quantum-vulnerable instances clearly across encryption, digital signature, key exchange, and hashing algorithms. 
• Strong compliance posture features for checking inventory against internal crypto policies or external standards. 
• Backed by ISARA’s PQC R&D heritage, providing a path toward implementing quantum-safe replacements after inventory. 

Limitations 

• Value is heavily dependent on the quality and breadth of existing NDR and EDR data; organizations starting from scratch need to deploy sensors first. 
• As a platform that “sits on top,” it provides high-level inventory rather than deep technical detail (e.g., it will not trace findings to the exact line of code). 
• OT or specialized systems are not visible unless their data feeds into the existing NDR/EDR. 
• Coverage is heavily dependent on input data fidelity; gaps in monitoring become gaps in the inventory. 

Best Suited For 

Large enterprises and government departments that have already invested in security monitoring tools and want to layer cryptographic insight on top, or organizations that need to satisfy regulatory auditors quickly using existing telemetry. 

Tychon ACDI 

Tychon, widely used in U.S. government endpoint security, offers a Quantum Readiness module implementing Automated Cryptographic Discovery and Inventory aligned to NSM-10 and the U.S. federal PQC mandate (HR 7535). The Tychon agent (or its agentless queries) scans each managed endpoint for certificates, soft certs, encryption libraries and versions, and active encryption usage on the host such as currently open TLS/SSL connections. 

Strengths 

• Compliance-focused: predefined queries and dashboards align directly to U.S. government cryptographic inventory requirements. 
• Continuous monitoring keeps the inventory up to date after the initial baseline. 
• Endpoint depth reveals things network-only tools cannot, such as applications doing encryption to a local file. 
• Familiar platform for federal users with existing Tychon deployments, with potential one-click remediation actions through the endpoint console. 

Limitations 

• Tailored for Windows and standard server OS endpoints; does not directly analyze custom application source code or monitor network traffic beyond what the host itself is doing. 
• Scope is narrower: primarily identifying known cryptographic artifacts on the host, not always tracing them to the originating process or application. 
• Not designed for OT environments such as PLCs or embedded systems. 
• Built primarily with U.S. government standards in mind, so familiarity is concentrated in federal and defense customers. 

Best Suited For 

U.S. federal agencies and contractors that need a rapid, automated way to comply with cryptographic inventory mandates, and as a triage tool in enterprise IT for finding deprecated protocols and outdated certificates across PCs and servers. 

AppViewX AVX ONE PQC Assessment Tool 

AppViewX, known for certificate lifecycle management, introduced the AVX ONE PQC Assessment Tool in 2025 to help organizations gain complete cryptographic visibility for post-quantum migration. It performs static analysis on application code repositories, examines software dependencies and libraries, inventories digital certificates, and reviews configuration files for insecure protocol settings. The tool generates a CBOM, computes a PQC readiness score, and provides step-by-step remediation guidance, with output in CycloneDX or CSV formats. 

Strengths 

• Comprehensive scope across application code, infrastructure configurations, and identity components (certificates and keys). 
• Highly actionable output: PQC readiness score, concrete remediation steps, and a tangible CBOM deliverable. 
• CI/CD integration plugs into build pipelines (GitHub Actions, AWS CodeBuild, etc.) to enforce checks and prevent regression. 
• Tailored dashboards and reporting for both technical and executive audiences. 

Limitations 

• Relatively new product that may evolve with user feedback. 
• Code-scanning value is highest for organizations with significant in-house development; mostly third-party software estates would benefit less from the code component. 
• Does not perform dynamic or network analysis, so cryptography in external black-box devices may not be discovered except via certificates. 
• CI/CD integration assumes a mature DevOps practice with automated builds. 

Best Suited For 

DevSecOps-driven enterprises preparing for post-quantum migration, especially organizations already using AppViewX for certificate lifecycle management. 

Open-Source Tools and Frameworks 

Not every cryptographic inventory effort requires commercial tools. The open-source ecosystem now includes the CycloneDX 1.6 CBOM standard, IBM’s CBOMkit (with components like Hyperion for source-code scanning and Theia for container scanning), CodeQL queries and SonarQube plugins for static analysis, Zeek scripts for network monitoring of TLS versions, cipher suites, and certificate chains, and various community scanners and academic prototypes. 

Strengths 

• Cost and flexibility: tools can be used freely and tailored to an organization’s specific technologies and pipelines. 
• Open standards like CycloneDX allow merging output from multiple tools into a unified CBOM. 
• Community-driven evolution as PQC and crypto-agility interest grows. 
• Suitable for highly sensitive environments that cannot use cloud-based vendor solutions. 

Limitations 

• Setup, tuning, and ongoing maintenance fall on the in-house team; static analysis often requires writing custom rules per language and library. 
• Accuracy may not match commercial tools without significant tuning. 
• Limited support if a tool has bugs or lacks support for a specific framework. 
• No built-in enterprise capabilities such as risk scoring engines, compliance dashboards, or proactive alerting (organizations typically build these themselves). 

Best Suited For 

Organizations with strong engineering teams, environments with strict data confidentiality requirements, pilot programs and proofs of concept, and as components of a larger multi-tool inventory strategy. 

How to Choose the Right Cryptographic Inventory Tool 

A cryptographic inventory program should be evaluated against a concrete checklist of capabilities. The questions that matter: 

• Coverage breadth — does the tool cover cloud KMS, HSMs, vaults, databases, network, file systems, key stores, and source code, or only one or two of these areas? 
• Source code cryptographic discovery — can it find cryptography embedded in application code, where post-quantum migration ultimately has to start? 
• Relationship and dependency modeling — is the inventory a graph or a flat list, and can it perform impact analysis when a CVE or CA compromise hits? 
• Cryptography-aware risk scoring — are findings scored using algorithm strength, expiry, key reuse, and configuration risk? 
• Continuous compliance — does it generate audit-ready evidence for FIPS 140-3, CNSA 2.0, CMMC 2.0, PCI-DSS 4.0, NSM-10, ISO 27001, and SOC 2 continuously? 
• PQC readiness — does it map findings to NIST FIPS 203/204/205 and produce a system-by-system migration roadmap? 
• Deployment flexibility — can it run agentless in regulated and air-gapped environments, with an optional agent only where needed? 
• Multi-tenancy — can a single deployment isolate multiple business units or MSSP clients? 
• Self-protection — does the platform encrypt and tag its own sensitive metadata? 
• Open standards — does it export CycloneDX-format CBOMs to avoid vendor lock-in? 

CBOM Secure was designed to address every one of these dimensions on a single platform, which is why we put it at the top of this list. In practice, most organizations end up assembling a complementary toolkit that combines a primary platform with one or two specialized tools to cover edge cases. Understanding what each product on this list does well, and where it does not reach, is the first step. 

Conclusion 

Cryptographic inventory has moved from a nice-to-have to a regulatory and operational necessity. With the post-quantum transition, 47-day certificate lifespans, and increasingly granular compliance mandates all hitting at once, organizations that cannot answer the question of where their cryptography lives will fail audits, suffer expensive outages, and miss critical risks. 

Each vendor covered in this blog has something useful to offer. The right approach for most enterprises is a single platform that delivers full-estate coverage, distinguishes active from dormant cryptography, supports PQC migration end to end, and produces audit-ready evidence on demand. Encryption Consulting’s CBOM Secure was built exactly for this purpose, combining the breadth of multi-source discovery, the depth of dependency-aware analysis, and the rigor of continuous compliance into one solution backed by a team that has been advising on PKI, HSMs, and encryption strategy for years. 

Cryptography is no longer something you check on once a year. It is the largest ungoverned attack surface in the enterprise, and it deserves the same operational rigor as identity, endpoint, or network security. CBOM Secure is how you bring that rigor in. To see it in action, request a demo or download the datasheet from the Encryption Consulting website.
