Post-quantum migration readiness
You end with an inventory of what you actually run, an exposure measured against how long your data has to stay secret, a sequenced roadmap with cost bands, and a briefing your risk committee can act on without a translator.
Why this is harder than it looks
The standards question is settled. NIST published the algorithms, and any competent firm can tell you which are approved. That part is a reading exercise.
What is difficult sits underneath it. Which HSMs in your estate will not hold the new key sizes. Which counterparty integration silently stops negotiating when a cipher suite changes. Which certificate chain nobody has owned since 2019. What happens to handshake latency on the payment path when signatures grow an order of magnitude, and whether your SLA survives it.
I have made those choices with a network in production and customers on it, and got some of them wrong the first time. That is the difference between a roadmap that survives contact with your estate and one that does not.
Four phases, and you see the shape of the answer by week two
Scope
A twenty-minute call, then a one-page written scope: what I examine, what you receive, what I need from your team, and the fixed price. Free, and yours to take elsewhere.
Inventory
The part nobody enjoys and everyone skips.
- Algorithms, key sizes, protocol versions and certificate authorities in use
- Where each is terminated: HSMs, load balancers, service meshes, payment rails, archives
- Counterparty and vendor dependencies, including the integrations nobody owns
- Data classes mapped to the confidentiality lifetime each actually needs
Exposure and roadmap
Shelf-life against migration time, system by system, so sequencing follows risk rather than convenience.
- What is exposed today under harvest-now-decrypt-later, ranked
- Crypto-agility: what can be swapped, what has to be rebuilt
- Sequenced roadmap with dependencies, effort bands and decision points
- The next ninety days, separated from what waits
The briefing, and the room
A board-level document, then a session presenting it to whoever has to act on it. Questions answered live, including the ones that come after the slides.
One route from the problem to a working system
Tell me what you are dealing with
A twenty-minute call on your situation, then a one-page written scope with a fixed price. Both free, and the scope is yours to take elsewhere.
Two working days, from me rather than an assistant.
What you send stays between us. An NDA before the first call is fine, and I will sign yours rather than send mine.
