Post-Quantum Cryptography
Protect long-lived data from decryption before a quantum computer can break it.
Why It Matters
Encrypted data can be recorded now and decrypted later, when a quantum computer can break the key exchange that protects it.
Records that must stay secret for years are exposed already. Most organisations cannot say where cryptography is used or which systems would break if it changed.
What We Do
Cryptography Inventory
We find every place cryptography is used, with the algorithm, key and owner.
Migration to Post-Quantum Standards
We move the estate to post-quantum algorithms in stages, with a rollback at each step.
Quantum-Safe Connections, Access and Certificates
Remote access, certificates and links stay safe through the change.
Crypto-Agility
Algorithms can be swapped through configuration, without rebuilding every system.
Hardware Security Modules
Keys stay inside certified hardware, and we check which models support the new algorithms.
What Changes for You
Know Where Cryptography Is
A maintained inventory of algorithms, keys and certificates, and the systems that depend on them.
Protect the Longest-Lived Data First
Systems are ranked by how long their data must stay secret and how exposed they are.
Change Algorithms Without a Rewrite
Cryptography sits behind clear interfaces, so the next standard is a configuration change.
How the Work Runs
We start with discovery, not a product. You name the system owners, the data retention rules and the partners who must accept a new algorithm.
Find the Cryptography
We scan code, traffic, certificates and hardware to build a cryptographic inventory. Your system owners confirm each result and the data it protects. The output is a cryptographic inventory with an owner for each result.
Rank by Exposure and Lifetime
We rank systems by how long their data must stay secret, how exposed they are and how hard they are to change. You agree the order. The output is a ranked migration list your risk team accepts.
Agree the Target and the Path
We choose the algorithms, the hybrid period, the certificate changes and the rollback. You decide the risk and the timing. The output is a written plan with dependencies and a rollback for each system.
Move in Stages
We introduce hybrid modes first and test each system against its partners. Every change has a rollback and a named owner. The output is a tested link or system, with the old path still available.
Prove Nothing Old Remains
We rerun discovery, retest the links and update the inventory. You receive the evidence and the remaining risks. The output is an updated inventory and a short evidence pack.
Team and Engagement Options
Who runs the cryptography migration, and what your platform teams keep.
A Team That Owns the Migration
A cryptography lead, a migration engineer and an inventory analyst work through the estate.
Work Beside Your Platform Teams
We work beside the teams that run each system and test with their partners.
A Clean Handover
You receive the inventory, migration plan and runbooks, each with a named owner.
Platforms and Technologies
Post-quantum algorithms are public-key methods built to resist a quantum attack. A hybrid connection combines one with a classical algorithm, so it stays safe if either fails. The NIST standards are FIPS 203 for key exchange, FIPS 204 for signatures and FIPS 205 for a second signature scheme. TLS 1.3 is the current version of the protocol that protects traffic. A CBOM is a list of every algorithm and key in your estate.

Questions
What security and technology leaders ask before a cryptography migration.
Why act before quantum computers arrive?
Because recorded traffic can be decrypted later. Data that must stay secret for years is exposed now, and a migration across a large estate takes time. Starting with the longest-lived records reduces that exposure first.
What drives the cost?
The number of systems, the hardware and certificate changes, your partners' readiness, and how long the data must stay secret.
Will the change break our systems?
Larger keys and signatures can affect older devices and partners. Hybrid modes, dual-stack certificates and partner tests reduce that risk. Every step has a rollback.
What does the cryptography migration not cover?
We do not replace your hardware security modules or certificate authority, and we cannot make a partner ready. We name those dependencies and plan around them.
Who owns the keys and the plan?
You do. We hand over the inventory, the migration plan and the runbooks, and remove our access when the work ends.
