The Enterprise

Challenges

The telecom's CipherTrust Manager had reached end-of-life on version 2.0. The organization lost vendor support, ran insecure protocols, and couldn't maintain consistent encryption across a multi-cloud environment serving millions of customers; three challenges stood out.

Inconsistent key management across multi-cloud

Each platform ran its own key management with separate rotation policies. AWS KMS handled S3 and EBS, third-party tools were configured differently elsewhere, and a unified encryption posture was impossible to enforce.

01 Key Management

Insecure protocols and expanding attack surface

The outdated CipherTrust Manager ran TLS 1.0, exposing systems to Advanced Persistent Threats. Without updated encryption practices, the attack surface expanded with every unpatched vulnerability.

02 Security

End-of-life, downtime & scan failures

EOL/EOS status meant no patches, updates, or vendor support. Routine backups and maintenance caused measurable downtime, and overlapping scans on the same data store failed and wasted resources.

03 Operations

The existing CipherTrust Manager version could no longer support the organization’s multi-cloud scale. Upgrading wasn’t optional; it was the foundation for everything else.

Our Offered

Solutions

The engagement covered environment assessment, upgrade path planning, zero-downtime migration, CTE agent compatibility, multi-cloud unification, and protocol hardening across a six-step version upgrade from 2.0 to 2.10.

Capability 01

Assessment & Upgrade Path Planning

Assessment covered cryptographic configuration, network setup, protocols, and deployment model. Regional distribution across multiple data centers and clouds required version 2.10 for high-availability and multi-region support, via 2.0 → 2.4 → 2.6 → 2.8 → 2.9 → 2.10.

Capability 02

Zero-Downtime Migration & CTE Agent Upgrade

PowerShell scripts migrated keys and policies into existing cloud platforms and databases with zero downtime. An agentless discovery module gave full visibility into key inventory across the hybrid environment, and CTE agents were upgraded to CM 2.9 with uninterrupted data-at-rest encryption.

Capability 03

Protocol Hardening & Multi-Cloud Unification

TLS 1.0 was eliminated and TLS 1.2 enforced as the minimum standard; full encryption support was enabled for microservices; and BYOK and HYOK models were deployed across AWS, Azure, and Google Cloud to unify encryption across the multi-cloud environment.

Capability 04

Performance, Compliance & Post-Quantum Readiness

High-speed tokenization and encryption improved performance in high-volume, mission-critical operations. The upgrade resolved EOL/EOS, restored vendor support and regular patches, achieved FIPS 140-2 Level 3 compliance, and added post-quantum cryptographic algorithm support for future resilience.

The result was a unified, high-performance encryption platform spanning multi-cloud and hybrid environments, with consistent key management, modern protocols, full vendor support, and post-quantum readiness.

The Overall

Business Outcome

The upgrade changed how the organization secures operations and maintains regulatory compliance. It closed existing vulnerabilities and set a scalable foundation for long-term security.

APT risk down, compliance restored

TLS 1.2+ and modern cryptographic standards replaced TLS 1.0 and cut APT exposure. Alignment with NIST SP 800-57, PCI DSS 4.0, and CMMC 2.0 ended audit failures and reduced the risk of fines, penalties, or reputational damage.

Unified multi-cloud and hybrid encryption

Consistent key management and encryption standards replaced the fragmented, platform-specific approach. BYOK and HYOK across AWS, Azure, and Google Cloud enabled secure, scalable microservices communications and reduced latency in high-volume operations.

Automated and future-proof

Automated key lifecycle and rotation cut manual work, cost, and human error. With EOL/EOS resolved, vendor support and patching returned, and post-quantum algorithm support readies the organization against future quantum threats.
