Cryptography
Design, review and implement cryptographic systems — key management, protocols, signing and secure storage.
Post-Quantum Security
Prepare for post-quantum cryptography before the deadline arrives
Plan and execute migration to post-quantum cryptography using the NIST-standardised algorithms ML-KEM and ML-DSA.
The problem
Why this matters
Data encrypted today with RSA or elliptic-curve key exchange can be recorded now and decrypted later once cryptographically relevant quantum computers exist. NIST published its first post-quantum standards in 2024, and regulators and governments are setting migration timelines for critical systems.
Common challenges
- No inventory of where quantum-vulnerable cryptography is used
- Long-lived sensitive data exposed to harvest-now, decrypt-later attacks
- Dependence on vendors and protocols that have not yet migrated
- Larger key and signature sizes affecting performance and protocols
Our approach
How we work
-
Discover
Inventory quantum-vulnerable algorithms across applications, protocols, devices and vendors.
-
Prioritise
Rank systems by data lifetime, exposure and migration complexity.
-
Pilot
Validate hybrid classical/post-quantum schemes in representative environments.
-
Migrate
Execute a phased migration plan with crypto-agility built in.

FAQ
Frequently asked questions
When do we need to start?
For systems protecting data that must remain confidential for many years, now. Discovery and inventory take time and do not depend on quantum computers arriving, so starting early reduces the cost and risk of migration.
Should we switch entirely to post-quantum algorithms immediately?
Most current guidance favours hybrid deployments that combine a classical and a post-quantum algorithm during the transition, preserving security if either is later found to be weak.
