You’re Compliant, But Is Your PKI Truly Protected?

Being compliant means meeting the minimum bar by following established rules and passing audits. It shows that your organization can align with frameworks, but it often reflects a snapshot in time rather than ongoing security. Resilience, on the other hand, is about preparing for the unexpected by building systems that can withstand failures, adapt to new threats, and recover quickly without disruption. This gap between compliance and resilience becomes especially important when examining PKI, as it can determine whether your business continues to operate smoothly or comes to a halt in the event of a sudden failure.

If your organization has invested in cybersecurity, it is likely that you have aligned your practices with established frameworks like NIST, PCI DSS, HIPAA, ISO, and other regulatory frameworks. You have rolled out technical controls, implemented robust authentication mechanisms, logged activities, deployed endpoint protection, and maybe even built layered defenses like multi-factor authentication and conditional access policies.

In short, you have staffed up, passed audits, and ticked all the right boxes, but there is a foundational question that often gets overlooked: Is your PKI healthy?

Most organizations assume the answer is yes. But what looks fine on the surface can hide serious risks. PKI health is not the same as overall security posture. Your security posture reflects the strength of your defenses across the organization, while PKI health is specifically about the reliability and proper functioning of your certificate and key infrastructure. Even an organization with a strong security posture can be severely impacted if its PKI fails.

An unhealthy or poorly maintained PKI is one of the most overlooked security risks in modern enterprise environments. When PKI fails, whether due to expired certificates, misconfigured CAs, or broken revocation chains, it disrupts authentication, access, and encryption simultaneously, bringing critical business processes to a halt.

Quick Answer: What Is the Difference Between PKI Compliance and PKI Resilience?

PKI compliance means meeting the minimum requirements of a framework audit at a point in time: key lengths, approved algorithms, certificate validity periods, and audit logging. PKI resilience means your PKI maintains secure, reliable operations continuously, even as certificates expire, cryptographic standards evolve, and infrastructure components fail. Compliance is the baseline. Resilience is the operational reality that keeps the business running.

Key Takeaways

• According to DigiCert’s Trust Pulse Survey (July 2, 2025), nearly half of all enterprises experienced certificate-related downtime in the past year, and only 34% have a complete and current view of their certificates (DigiCert 2026 Global PKI Research Report, June 2026). Compliance audits do not close this gap.
• The CA/Browser Forum’s Ballot SC-081v3 (April 2025) reduces maximum public TLS certificate validity to 200 days (March 2026), 100 days (March 2027), and 47 days (March 2029). Manual certificate management cannot support a 47-day renewal cadence at any meaningful certificate volume.
• NIST finalized FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) in August 2024. Organizations without crypto-agile PKI infrastructure cannot migrate to post-quantum standards without rebuilding their entire CA hierarchy.
• Real-world incidents including the Equifax breach (2017), DigiNotar CA compromise (2011), and ServiceNow root certificate failure (2024) all demonstrate that compliance did not prevent catastrophic PKI failures with multi-million-dollar consequences.
• A 2024 study found that the average cost of one minute of downtime has increased to approximately $9,000. A single expired certificate caused the Microsoft Teams outage in 2020, affecting millions of users despite the organization meeting compliance requirements.

Who Should Care About PKI Resilience

PKI resilience is not a single team’s responsibility. Every role below has a direct stake in closing the gap between compliance and operational security.

Role	Why It Matters	Action Item
PKI Admins	Own CA hierarchy health, certificate lifecycle automation, revocation infrastructure, and HSM management; first to be paged when a certificate expires	Deploy CLM automation; build a complete cryptographic inventory via CBOM Secure; confirm CRL and OCSP responders are reachable and monitored; document every CA owner
Security Architects	Define cryptographic policy: algorithm standards, validity period requirements, trust model, and PQC readiness planning	Enforce NIST SP 800-131A algorithm floors; retire RSA-1024 and SHA-1 certificate templates; design CA hierarchy for crypto-agility including FIPS 203/204/205 migration
Platform / DevOps Teams	Rely on certificates being issued and renewed automatically in CI/CD pipelines, Kubernetes, and cloud workloads; manual renewal blocks deployments	Integrate ACME-based certificate issuance into pipelines; prohibit self-signed certificates in production; automate short-lived certificate issuance for container workloads
Compliance Teams	Must demonstrate that PKI controls are continuously enforced, not just point-in-time compliant; auditors increasingly expect continuous monitoring evidence	Integrate CA event logs with SIEM for continuous audit trail; schedule quarterly PKI health checks beyond annual audit scope; confirm CLM provides automated compliance reporting
CISOs	Own the risk register entry for certificate outage risk, PKI operational resilience, CA mis-issuance exposure, and quantum vulnerability	Fund CLM automation and CBOM discovery tooling; require a current cryptographic inventory; include PKI resilience and PQC readiness in board-level risk reporting

Beyond Compliance: Strengthening PKI Security

Compliance frameworks are designed to set minimum standards, not to guarantee resilience. They define the baseline requirements for key lengths, approved encryption algorithms, certificate validity periods, and audit logging that organizations must satisfy.

Compliance is about proving you are secure today, while resilience ensures your PKI stays secure and operational tomorrow. Resilience is the ability of your PKI to maintain secure, reliable operations continuously, even as certificates expire, cryptographic standards evolve, or infrastructure components fail. It includes proactive monitoring, automated lifecycle management, rapid incident response, and the capacity to adapt to both planned changes and unexpected disruptions without service interruptions.

What compliance leaves out are the day-to-day operational challenges of PKI: continuous monitoring, automated certificate renewals, detection of shadow or orphan certificates, and readiness for cryptographic shifts like post-quantum migration. A PKI can appear fully compliant on paper while still being fragile in practice, leaving it vulnerable to expired certificates, misconfigured trust chains, or outdated cryptography that lingers in templates.

Think of it like aviation. An aircraft can pass inspections and meet all regulatory requirements, but if it is not maintained between checks, small issues can build into catastrophic failures mid-flight. Similarly, a PKI that passes an audit may still be dangerously close to failure if it is not actively managed, monitored, and kept agile for future cryptographic shifts.

The risks are not theoretical. In 2020, Microsoft Teams experienced a widespread outage because an authentication certificate expired unexpectedly. Even though the organization met compliance requirements, the expired certificate prevented users from authenticating and accessing services, causing hours of disruption across multiple regions. This incident highlights how even compliant PKI systems can fail operationally if certificates are not actively monitored and managed.

What Is PKI and Why Should You Care?

Public Key Infrastructure (PKI) is the foundation of digital trust in any modern IT environment. It provides mechanisms that enable secure communication, trusted identity verification, and encrypted data exchange. At its core, PKI enables five essential functions: identity, authentication, confidentiality, data integrity, and access control.

Identity

PKI ensures that every entity in your environment, whether a user, device, server, or application, has a unique, verifiable identity through digital certificates issued by a trusted Certificate Authority (CA). Each certificate contains a unique public key and metadata about the entity it represents, such as a username, device ID, or domain name. The CA acts as a trusted third party, vouching for the authenticity of the entity, allowing you to confirm who is connecting to your systems, detect rogue devices, and prevent unauthorized access from impersonated accounts.

Authentication

Claiming an identity is not enough; it must be proven. PKI enables authentication by using certificates to prove a user or device is who they claim to be. Each certificate has a public key, and only the owner with the matching private key can successfully authenticate. This provides strong cryptographic authentication, mitigates credential theft attacks, and strengthens multi-factor authentication.

Confidentiality

PKI provides the keys and trust model needed to encrypt sensitive communications and data in transit. Using public-private key pairs, data encrypted with a public key can only be decrypted with the corresponding private key. This protects data from eavesdropping, prevents tampering, and keeps information unreadable even if communications are intercepted.

Data Integrity

PKI ensures that information has not been altered in transit. The sender signs the data with their private key, creating a digital signature, and the recipient uses the sender’s public key to verify it. If the signature matches, the recipient can trust that the data is authentic and unchanged, protecting against tampering and unauthorized modifications.

Access Control

Certificates issued through PKI define and enforce who has permission to access specific systems or resources by binding certificates to specific roles, policies, or systems. This ensures that users or machines can only access authorized systems, reduces lateral movement during a breach, and enforces least-privilege access policies.

In practical terms, PKI is what makes it possible to securely log in to systems, access corporate VPNs, encrypt emails, sign software, authenticate devices, and build trust between internal and external systems. Whether it is a smart card login, a digitally signed firmware update, or a trusted TLS handshake, PKI is working silently in the background to enforce trust.

Ignoring PKI risks does not make them disappear. Unmanaged or neglected PKI is a silent vulnerability that often shows no warning until something critical stops working. If your organization relies on secure access, trusted identities, or encrypted communication, which virtually all do, then you absolutely need to care about the state of your PKI.

The Hidden PKI Risks of Compliant Organizations

Despite rigorous audits, many organizations remain vulnerable due to overlooked operational gaps. A study by DigiCert and Ponemon Institute found that 62% of organizations experienced outages or security incidents caused by digital certificate issues, and 43% of organizations do not have a complete inventory of the certificates they manage, creating potential blind spots. According to DigiCert’s Trust Pulse Survey (July 2, 2025), nearly half of all enterprises experienced certificate-related downtime in the past year.

Even if your PKI meets all compliance requirements, hidden operational and security risks can still threaten availability and trust. The five most common gaps are covered below.

1. Point-in-Time vs. Real-Time Security

Audits validate PKI at a specific moment in time. Certificates can expire unexpectedly, revocation chains may break, or subordinate CAs may go offline, causing outages weeks or months after the audit ends. Without continuous monitoring and automated alerts, these issues often remain undetected until critical systems fail.

2. Cryptographic Agility Gaps

Compliance frameworks often accept algorithms like RSA-2048 or ECC, which are secure today. But with NIST finalizing FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) in August 2024, the post-quantum migration timeline is real. A compliant PKI that cannot easily migrate to new algorithms leaves organizations exposed, potentially requiring emergency-wide re-issuance of keys and certificates. Preparing for PQC involves validating that applications, servers, network devices, and HSMs support new algorithms; updating certificate profiles and trust hierarchies; and planning phased rollouts to minimize service disruption. Start with the PQC Readiness assessment and the PQC Center of Excellence.

3. Shadow and Orphan Certificates

Certificates issued outside central IT management in test labs, developer environments, or legacy systems often escape audits. Examples include TLS certificates for internal staging servers, self-signed certificates used in development pipelines, certificates embedded in legacy applications, or device certificates for IoT sensors. A single neglected certificate may trigger service outages, break authentication chains, or provide an attack vector, especially if it uses weak cryptography or default configurations. Use CBOM Secure to discover and inventory all certificates across hybrid and multi-cloud environments.

4. Weak Operational Practices

Using long-lived certificates such as two-year or three-year certificates increases the risk of private key compromise, reliance on outdated algorithms, and challenges in managing the certificate lifecycle. The CA/Browser Forum’s Ballot SC-081v3 (April 2025) reduces maximum public TLS certificate validity to 47 days by March 2029, making long-lived certificates operationally unsustainable and automation essential.

5. Limited Visibility and Monitoring

Most compliance frameworks do not require continuous certificate inventory, real-time monitoring, or automated reporting for certificates and keys. Without these measures, expired, misconfigured, or compromised certificates can silently accumulate, creating blind spots that threaten both system availability and security.

The Business Impact of PKI Failures

PKI is deeply embedded in nearly every part of enterprise IT, from securing logins and encrypting traffic to authenticating devices and enabling trusted transactions. When it fails, the impact spreads quickly across business operations, causing disruptions that go far beyond IT.

1. Service Outages and Downtime

A single expired or misconfigured certificate can bring down websites, APIs, or authentication systems, instantly halting business processes. For customer-facing platforms like e-commerce or SaaS services, even brief outages can translate into lost revenue and broken customer experiences. According to a 2024 study, the average cost of a single minute of downtime has increased from $5,600 to approximately $9,000.

2. Security Breaches and Data Exposure

Weak algorithms, certificates using insecure key sizes like RSA-1024, or unmanaged shadow certificates can be exploited by attackers to impersonate systems, intercept communications, or gain unauthorized access. These lapses create direct pathways for breaches that compromise sensitive customer data, intellectual property, and critical infrastructure.

3. Regulatory and Compliance Failures

Frameworks such as PCI DSS, HIPAA, and GDPR mandate strong encryption and reliable certificate management. When PKI incidents result in service outages or data exposure, organizations risk failing audits, incurring heavy fines, and facing additional oversight, all of which impact both financial stability and brand credibility.

4. Supply Chain and Partner Disruptions

PKI underpins trust between business partners, vendors, and third-party integrations. An expired signing certificate or a broken trust chain can disrupt vendor APIs, federated identity systems, and software distribution. For example, if a logistics provider’s SSL/TLS certificate expires, a retailer cannot retrieve real-time shipping updates or process new orders, causing shipment delays, missed SLAs, and customer dissatisfaction. In tightly integrated supply chains, even minor certificate failures have ripple effects across multiple partners.

5. Long-Term Reputation Damage

Customers and partners expect seamless, secure digital interactions. Browser warnings, login failures, or insecure communication caused by PKI lapses erode confidence and trust. Even after technical fixes are applied, reputational damage often lingers, influencing customer loyalty and competitive standing in the market.

Real-World Cases from Neglected PKI

Even if your PKI appears compliant, neglecting its management can lead to outages, breaches, and operational chaos. The following real-world incidents show how even minor oversights in certificates or Root CAs can have major consequences.

1. Equifax Data Breach (2017)

One of the most infamous security breaches in history stemmed in part from an expired PKI certificate. For 10 months, the expired certificate prevented Equifax from inspecting encrypted traffic, leaving attackers free to exploit a known vulnerability in the Apache Struts server. Personal data of more than 145 million consumers was compromised. A single overlooked certificate eliminated critical visibility and led to massive financial and reputational damage.

2. DigiNotar CA Compromise (2011)

Dutch certificate authority DigiNotar was hacked, and attackers issued over 500 fraudulent certificates for domains like Google and Skype. This broke the integrity of the trust chain at its core. Browsers revoked certificates issued by DigiNotar, the company went bankrupt, and it became a landmark case of why CA security and monitoring are critical.

3. Twitter Outage (2022)

In 2022, Twitter experienced a major outage caused by an internal systems change that disrupted core services across the platform. The incident highlighted how lapses in PKI management can affect not only external user-facing systems but also internal operational tools that employees rely on daily.

4. ServiceNow Root Certificate Failure (2024)

ServiceNow, a leading enterprise SaaS platform, faced a significant disruption when root certificate mismanagement undermined its services. The failure illustrated how issues at the top of a trust hierarchy ripple across dependent systems, breaking authentication and trust across thousands of organizations relying on ServiceNow for critical workflows.

5. California COVID-19 Reporting Issue (2020)

During the height of the pandemic, California’s COVID-19 reporting system failed to process thousands of case reports due to an expired certificate. The result was a backlog of unreported cases and delayed public health decisions at a critical time. PKI failures are not limited to corporate IT; they can directly affect public safety and crisis response.

These incidents all demonstrate that compliance alone cannot prevent failures. Continuous PKI monitoring, automated certificate management, and proactive governance are essential to maintain security and operational resilience.

The Problem: PKI Is Treated Like a Set-and-Forget Tool

Public Key Infrastructure often fades into the background once it is deployed. Many organizations treat PKI as a one-time project: they design it, configure it, pass the audit, and then move on. The result is that PKI becomes invisible until something breaks.

Common signs of this set-and-forget approach include:

1. Abandoned Certificate Authorities

Root or intermediate CAs are still trusted but have no defined owner, no documented key storage policy, and no recovery procedure if a private key is lost or compromised. When no one owns a CA, no one monitors it, patches it, or responds when it misbehaves.

2. Outdated Cryptography

Legacy certificate templates still issue weak keys (RSA-1024, ECC with unsupported curves) or deprecated hash functions like SHA-1. These are often left in place for backward compatibility, exposing services to downgrade and collision attacks. NIST SP 800-131A disallows these, but compliance audits do not always scan every template in the CA hierarchy.

3. Broken Revocation Infrastructure

CRL Distribution Points (CDPs) or OCSP responders are missing, misconfigured, or unreachable. As a result, clients may incorrectly accept revoked certificates as valid. This is the exact failure mode that contributed to the Equifax breach: an expired certificate meant revoked certificates went undetected for months.

4. Long-Lived Certificates

Two to three-year validity periods still exist in many environments, increasing the attack window if keys are compromised and making the certificate lifecycle harder to manage. The CA/Browser Forum’s 47-day mandate (arriving March 2029 per Ballot SC-081v3, April 2025) will make long-lived public TLS certificates non-compliant. Organizations that have not begun automating renewal will be caught unprepared.

5. Lack of Monitoring Hooks

PKI health is not integrated into SIEMs, certificate lifecycle tools, or uptime monitoring, allowing expired, misused, or rogue certificates to go unnoticed until they cause outages. Without SIEM integration, there is no real-time alert when a certificate is issued from an unapproved CA, a revocation responder goes offline, or a key generation ceremony is performed outside policy.

Building PKI Resilience Beyond Compliance

If compliance is not enough, the answer is to take proactive steps to strengthen infrastructure, operational practices, and cryptographic agility. Here are the six strategies that move organizations from compliant to genuinely resilient.

1. Maintain a Complete Cryptographic Inventory

A resilient PKI starts with visibility. Track every certificate, key, and cryptographic dependency across on-premises systems, cloud services, and shadow IT environments. Include both production and non-production assets, expired and orphaned certificates, and unmanaged CAs. A comprehensive inventory via CBOM Secure allows you to identify vulnerabilities, plan renewals, and prevent unexpected outages. An inventory that cannot be produced on demand for an auditor is an inventory that cannot be trusted.

2. Implement Continuous Monitoring and Alerts

Audits provide a snapshot in time, but PKI risks evolve daily. Continuous monitoring ensures that certificate expirations, revocations, or misconfigurations are detected in real time. Automated alerts notify administrators when certificates are approaching expiry, CA trust chains are broken, or cryptographic standards are outdated. Integrate CA event logs with your SIEM so that anomalous issuance events, failed enrollment attempts, and revocation responder failures generate real-time alerts.

3. Automate Certificate Lifecycle Management

Manual certificate issuance, renewal, and revocation are prone to human error and operational delays. CertSecure Manager automates the entire lifecycle of certificates, ensuring that keys are rotated on schedule, revoked immediately if compromised, and deployed without service interruption. Automation also enforces policy compliance consistently across all environments. Integrating certificate management into CI/CD pipelines allows certificates to be automatically renewed and deployed during application updates or infrastructure changes, eliminating manual intervention in dynamic environments.

4. Plan for Cryptographic Agility

Cryptography standards evolve with time, and PKI must be prepared to adapt. Plan your infrastructure to support algorithm transitions from RSA/ECC to post-quantum cryptography (PQC) without breaking existing services. This involves designing flexible CA hierarchies, maintaining compatible certificate templates, and testing interoperability before deployment. NIST finalized FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA) in August 2024. Begin your migration planning now via the PQC Readiness assessment and PQC Center of Excellence.

5. Adopt Short-Lived Certificates

Short-lived certificates minimize the impact of compromised keys and reduce reliance on revocation mechanisms. The industry is shifting toward 90-day and even 47-day TLS certificates to improve security posture. Moving from traditional 398-day certificates to 47-day certificates results in up to eight times more renewals annually, making automation essential. Automated management via CertSecure Manager ensures continuous validity while reducing administrative overhead and human error.

6. Conduct Regular PKI Health Checks

Beyond compliance audits, perform internal PKI assessments to verify that all certificates, keys, and CA configurations align with modern cryptographic standards. Health checks should include verification of trust chains, revocation mechanisms, algorithm strengths, and HSM configurations. Regular assessments identify hidden risks before they impact operations.

Conclusion

A compliant PKI is just the starting point. Many organizations assume that passing audits and ticking checkboxes is enough, but without active management, monitoring, and regular updates, hidden risks quietly accumulate. Expired certificates, weak cryptography, orphaned CAs, and misconfigured revocation infrastructure can disrupt operations, expose sensitive data, and create opportunities for attackers. True PKI resilience requires visibility, proactive lifecycle management, and readiness for evolving cryptographic standards.

Do not wait for an expired certificate to teach you how critical your PKI really is. Treat PKI like the core infrastructure it is. Monitor it, own it, and strengthen it.

Frequently Asked Questions

What is the main takeaway from You’re Compliant, But Is Your PKI Truly Protected?

Compliance frameworks set a minimum bar at a point in time, but they do not guarantee PKI resilience. Organizations that pass audits can still suffer outages, breaches, and operational disruptions from expired certificates, shadow CAs, outdated cryptography, and broken revocation infrastructure. True PKI protection requires continuous monitoring, automated lifecycle management, cryptographic agility, and regular health checks beyond what audits require.

Why does PKI resilience matter for enterprise PKI teams?

Enterprise PKI teams are responsible for the cryptographic identity of every user, device, server, and application in the organization. When PKI fails, authentication, access, and encryption all fail simultaneously. According to DigiCert’s Trust Pulse Survey (July 2, 2025), nearly half of enterprises experienced certificate-related downtime in the past year, and only 34% have a complete and current view of their certificates. PKI teams that rely solely on annual audits leave the gaps between audits completely unmonitored.

What risks increase if PKI is managed manually without continuous monitoring?

Manual PKI management increases the risk of certificate expiry outages (a 2024 study found the average cost of one minute of downtime is approximately $9,000); shadow and orphan certificates accumulating without being discovered; deprecated algorithms like RSA-1024 and SHA-1 persisting in templates because no automated scan catches them; and broken CRL or OCSP revocation infrastructure going undetected until a compromised certificate is incorrectly accepted as valid.

Which teams should own PKI resilience?

PKI admins own CA hierarchy health, certificate lifecycle automation, revocation infrastructure, and HSM management. Security architects own cryptographic policy including algorithm standards and PQC readiness planning. Platform and DevOps teams own certificate integration into CI/CD pipelines. Compliance teams own evidence collection and audit readiness. CISOs own the risk posture and must fund CLM automation and CBOM Secure discovery tooling.

How does PKI resilience connect to certificate lifecycle management?

Certificate lifecycle management (CLM) is the operational layer that makes PKI resilience possible. Without automated CLM, certificates expire unnoticed, shadow certificates accumulate, and manual renewal processes fail under the 47-day renewal cadence arriving by March 2029. CertSecure Manager automates the entire certificate lifecycle, enforces algorithm policy consistently across all CAs, provides real-time expiry monitoring, and integrates with CI/CD pipelines and cloud environments.

How should organizations measure PKI resilience success?

Key metrics include: number of certificate expiry-related outages per quarter (target: zero); percentage of certificates under automated lifecycle management (target: 100%); percentage of the certificate estate with no deprecated algorithms in production; time to produce a complete cryptographic inventory on demand via CBOM Secure (target: under one hour); and percentage of shadow or unmanaged certificates discovered and remediated within 30 days. Track these quarterly.

What should be audited or monitored regularly in a PKI resilience program?

Monitor continuously: certificate expiry timelines across all environments; CRL and OCSP responder health; failed certificate enrollment attempts; and certificates issued from unexpected or unapproved CAs. Audit quarterly: algorithm compliance across the full certificate inventory; CA trust chain health and root CA ownership documentation; revocation infrastructure reachability; and HSM tamper log review. Integrate CA event logs with SIEM for real-time alerting.

How does PKI resilience affect cloud, hybrid, or multi-CA environments?

Cloud, hybrid, and multi-CA environments multiply PKI resilience risks because certificates are issued from multiple sources under different policies and without unified visibility. Shadow certificates are most common in these environments, issued in developer accounts and cloud workloads outside central IT oversight. A CLM platform providing unified visibility and policy enforcement across all CA sources, combined with CBOM Secure for cryptographic discovery, is essential to closing the gap.

What common mistakes should teams avoid when building PKI resilience?

The most common mistakes are: treating PKI as set-and-forget infrastructure and only reviewing it at audit time; not building a cryptographic inventory before deploying CLM automation, leaving shadow certificates undiscovered; not integrating CA event logs with the SIEM; continuing to use long-lived two-year or three-year certificates when 47-day certificates require automation; and not assigning named owners to every root and intermediate CA so that abandoned CAs go unnoticed.

What should be refreshed quarterly in a PKI resilience program?

Refresh quarterly: complete cryptographic inventory via CBOM Secure to catch shadow and unmanaged certificates; algorithm compliance audit against current NIST SP 800-131A guidance; CA ownership documentation confirming every root and intermediate CA has a named owner and documented recovery plan; revocation infrastructure health check for CRL and OCSP responders; and certificate template review flagging any templates still issuing RSA-1024, SHA-1, or long-lived certificates.
