Case Study: Quantum Security

Client: Large financial services provider with long-lived encrypted data and global compliance requirements.

Challenge

The provider had critical archives encrypted with classical algorithms at risk of future quantum decryption. Existing systems had hundreds of cipher endpoints and stringent availability demands.

Solution

• Conducted full cryptographic asset discovery and classified data by sensitivity and retention timelines.
• Designed a phased migration to NIST-approved post-quantum algorithms with hybrid operations to reduce risk.
• Built vendor compatibility assessments and implemented fail-safe rollback paths.
• Validated through live integration tests and compliance reporting updates.

Results

• Quantum risk score decreased by 82% across core banking systems.
• Post-quantum migration completed on 63% of critical endpoints within 1 year.
• No service disruptions during rollout; SLA uptime maintained at 99.97%.
• Regulatory exam comfort increased as evidenced by an 18% improvement in security maturity scores.
