PQC & Security

A post-quantum plan that reaches production.

We help security and engineering teams locate material cryptographic exposure, choose a defensible transition pattern and implement it in systems that still have to perform, interoperate and remain operable.

The decision
What needs protection first?
  1. 1
    Data lifetimeHow long must confidentiality hold?
  2. 2
    System exposureWhere can traffic or ciphertext be captured?
  3. 3
    Change difficultyWhat cannot be patched or replaced quickly?
What changes

PQC migration is a systems problem, not an algorithm checkbox.

New key exchange and signature schemes affect certificate hierarchies, message sizes, hardware limits, protocols, performance and every team responsible for operating the result.

The right first move is not to replace everything. It is to identify the data and trust paths where waiting creates a larger future constraint.

Trust path Selected, gold plane marks move early Drag to rotate
Trust pathWhy it moves earlyEngineering question
Long-lived data

Harvest now, decrypt later exposure starts before a cryptographically relevant quantum computer exists.

Where are keys created, wrapped, rotated and recovered?

PKI & signing

Certificate and signature transitions cross organisational and vendor boundaries.

Which verifiers, roots and formats must coexist?

Network protocols

Hybrid exchanges increase payloads and expose hidden compatibility limits.

What changes under realistic traffic and failure?

Identity systems

Biometric and identity evidence can stay sensitive for decades.

How is the payload protected across every boundary?

Start at the decision you need to make.

Three ways in. Each ends with something your team can act on without us in the room.

01 / For teams that need to know where to start

Cryptographic exposure review

Inventory representative protocols, certificates, libraries and long-lived data, then rank exposure by impact, lifetime and replacement difficulty.

Output: priority map and migration brief
02 / For teams choosing a transition pattern

PQC architecture pilot

Design a hybrid classical and post-quantum path, integrate it into one representative flow, and measure compatibility, payload, latency and operational impact.

Output: working proof and decision record
03 / For teams ready to implement

Production migration

Engineer rollout, key and certificate lifecycles, telemetry, recovery and handover around the systems that own the risk.

Output: deployed control and operating playbook

Standards ledger

Grounded in published standards. Honest about implementation context.

Using a named primitive does not make a complete system compliant. We document assumptions, integration choices and the evidence needed to review the whole control.

A useful first step

Choose one system where the cost of waiting is clear.

We can examine its data lifetime, trust boundaries and migration constraints, then leave your team with a decision-ready path.
