Post-Quantum Security
Plan and execute migration to post-quantum cryptography using the NIST-standardised algorithms ML-KEM and ML-DSA.
Cryptography
Cryptography engineered correctly, not just switched on
Design, review and implement cryptographic systems — key management, protocols, signing and secure storage.
The problem
Why this matters
Cryptographic failures rarely come from broken algorithms. They come from implementation details: hard-coded keys, nonce reuse, weak randomness, unauthenticated encryption, poor key rotation and certificates nobody tracks.
Common challenges
- Keys embedded in source code, configuration or container images
- Inconsistent algorithm and library choices across teams
- No complete inventory of certificates, keys and their owners
- Custom cryptographic code without expert review
Our approach
How we work
-
Inventory
Build a cryptographic bill of materials: algorithms, keys, certificates and libraries.
-
Review
Assess designs and implementations against current standards and known pitfalls.
-
Remediate
Replace weak primitives and centralise key management behind well-tested libraries.
-
Prepare for change
Build crypto-agility so algorithms can be replaced without application rewrites.

FAQ
Frequently asked questions
Should we write our own cryptographic code?
Almost never. We recommend well-reviewed libraries and focus custom work on correct composition, key management and protocol design.
