"Harvest now, decrypt later" modelling
Which data will still matter in ten years? Which data travels today under cryptography that won't hold? We establish your real exposure to the quantum risk.

Service · Specialty in development
Prepare your cryptography for the post-quantum era
Inventory what you encrypt, measure the real exposure, and sequence a migration to post-quantum standards — without halting the business.
In development
A specialty backed by a published method (see Research) and NIST standards (ML-KEM, ML-DSA, SLH-DSA). Every engagement is scoped precisely; we say so when a need falls outside our current perimeter.
Why now
The clock is already ticking
Encrypted data captured today can be decrypted tomorrow. For any secret that must stay confidential for years — medical records, intellectual property, legal archives — the threat doesn't wait for the quantum machine to arrive.
Mosca's theoremX + Y > Z
Migration time (Y) plus required secrecy (X), beyond the quantum horizon (Z), opens an exposure window.
Our method
You can't migrate what you don't know you have
Four successive passes, from broadest to most precise. Each pass produces a usable deliverable, even if you stop there.

What we do
Three interventions, in order of risk
Cryptographic inventory
A four-pass mapping of the algorithms, keys, protocols and certificates in use across your organisation — down to the primitive, and down to the lifetime of the data protected.

Post-quantum roadmap
A migration plan toward standardised algorithms (ML-KEM, ML-DSA), sequenced by risk priority, compatible with your operational constraints and built for crypto-agility.

What you receive
Usable deliverables, not a report to archive
01
Documented inventory
Algorithms, key sizes, protocols, certificates and data lifetime — where they are used and what they protect.
02
Defensible prioritisation
Your exposure ranked using Mosca's model (X + Y vs Z): urgent, important, deferrable.
03
Sequenced roadmap
What to migrate, in what order, to which algorithms, on what milestones — at your operational pace.
04
Crypto-agility
An architecture ready to absorb the next algorithm transition without a new project.
Who it's for
Organisations with long-life secrets
SMEs, regulated structures and sectors where data must stay confidential for years: healthcare, legal, industry, finance, research. If your data keeps its value a decade from now, the exposure already exists — and migration takes time.
