THE SECURET METHOD / POST QUANTUM READINESS
Plan an orderly transition to post-quantum cryptography.
Start with cryptographic exposure and dependencies, then sequence migration around risk, interoperability and lifecycle.
- 01
Discover
Crypto inventory, PKI and key dependencies
- 02
Classify
Sensitive data lifespan and algorithm exposure
- 03
Prioritise
Systems, vendors, protocols and business impact
- 04
Migrate
Crypto-agile designs and staged transition
- 05
Validate
Interoperability, testing and ongoing inventory
Long-lived confidentiality needs and third-party constraints influence migration priority.
Illustrative delivery model. Activities are tailored to the engagement scope, environment and risk profile.
WHO THIS IS FOR / BUSINESS CONTEXT
When organisations call us.
Who this is for
Security architects, PKI teams, infrastructure owners, procurement leads and risk managers preparing long-lived systems and sensitive information.
Common triggers for an engagement include:
- A client, regulator or board has asked for a credible PQC plan
- Sensitive records need confidentiality for many years
- PKI, VPN, identity or code-signing renewal is already scheduled
ENGAGEMENT SCOPE
What we examine and design.
Work is proportionate to the system, its operating context and the decisions you need to make.
Discovery of public-key algorithms, protocols and certificates
Cryptographic bill of materials (CBOM) and dependency mapping
Harvest-now-decrypt-later risk prioritisation
NIST FIPS 203, 204 and 205 impact assessment
Crypto-agility architecture and supplier readiness review
Hybrid deployment options and migration sequencing
Pilot readiness criteria, costed roadmap and executive briefing
OUR APPROACH
How we deliver.
Inventory first. Prioritise by information lifetime and system changeability, and design a staged transition aligned to supported vendor roadmaps.
Standards and platforms
NIST FIPS 203 (ML-KEM) · FIPS 204 (ML-DSA) · FIPS 205 (SLH-DSA)
Where we draw the line.
We advise on migration readiness and pilot designs. We do not certify cryptographic modules or claim all products currently support NIST PQC standards.

Questions worth asking.
Answers are scoped to the service described here, not guarantees for an individual environment.
What is crypto-agility?
The ability to change cryptographic algorithms, keys and implementations without rebuilding an entire application or ecosystem.
Should every system migrate immediately?
No. Prioritisation depends on exposure, confidentiality duration, algorithm inventory, interoperability and supported vendor capabilities.
