Migrate to post-quantum cryptography without breaking production
A cryptographic migration is a multi-year programme, not a library swap. We find every use of quantum-vulnerable crypto, sequence the move by data shelf life and policy deadline, and execute it, starting with the traffic already exposed to harvest-now-decrypt-later.
What migration covers
We treat migration as a sequenced programme with a defensible order of operations: inventory first, exposed traffic next, agility throughout.
- A cryptographic inventory that maps every algorithm, key, certificate, and protocol in your estate: the map you cannot migrate without.
- A prioritized roadmap sequenced by data shelf life and the deadlines in CNSA 2.0 and the federal timeline.
- Hybrid TLS key exchange (X25519MLKEM768) rolled out to close the harvest-now-decrypt-later window first, without breaking classical clients.
- Crypto-agility built in, so the next algorithm change is a configuration update, not another migration programme.

Frequently asked questions
Is migrating to post-quantum crypto just a library swap?
No. It is a multi-year programme. We find every use of quantum-vulnerable cryptography, sequence the move by data shelf life and policy deadline, and execute it, starting with the traffic already exposed to harvest now, decrypt later.
How do you decide what to migrate first?
From a cryptographic inventory of every algorithm, key, certificate, and protocol, then a roadmap ordered by how long your data must stay secret and by the deadlines in CNSA 2.0 and the federal timeline.
Will this break existing clients?
No. Hybrid TLS key exchange (X25519MLKEM768) closes the harvest-now-decrypt-later window first while classical clients keep working.
What is crypto-agility, and why does it matter?
The ability to change algorithms through configuration rather than another migration programme. We build it in so the next change is a config update, not a repeat of this project.
Where do you start?
With inventory. You cannot migrate what you cannot see, so the first deliverable is a map of where cryptography lives across your estate.
How does this relate to an audit?
The audit produces the inventory and roadmap; the migration executes them. They are two stages of the same programme.
