The quantum threat is not a future problem. Encrypted traffic intercepted today can be stored cheaply and decrypted the moment a cryptographically relevant quantum computer exists. Any data whose confidentiality must outlive the migration is therefore already at risk. Mosca's theorem makes the deadline concrete:
migration time + confidentiality term > time to quantum computer
If this holds for your data, and for long-lived data it usually does, the clock is already running.
Module-lattice key encapsulation. The post-quantum replacement for the key exchange that protects data in transit.
Module-lattice digital signatures. Quantum-safe authenticity for certificates, software signing and identities.
Stateless hash-based signatures. A conservative fallback built on well-understood hash function security.
NIST finalized these standards in 2024, and the practical path is available today: TLS 1.3 with hybrid ML-KEM key exchange. There is no TLS 1.4 coming to solve this for you. Regulation is moving too, with the EU coordinated PQC roadmap and NIS2 putting crypto governance on the organisation's agenda.
National PQC transition roadmaps established, pilots for high- and medium-risk use cases initiated.
PQC transition for high-risk use cases completed. Quantum-safe software and firmware upgrades enabled by default.
PQC transition for medium-risk use cases completed, low-risk as much as feasible.
Even if you wanted to be fully post-quantum today, your suppliers won't let you. Microsoft plans to be “quantum safe enabled” by the end of 2029 and to phase out legacy cryptography between 2030 and 2035. Measured against a harvest-now-decrypt-later adversary that is already collecting, that is slow. Most vendor stacks tell a similar story.
Waiting for the ecosystem to catch up is not a strategy. Organisations that get ready now, knowing where their cryptography lives, which chains are critical and which suppliers are the bottleneck, can migrate the moment each dependency unlocks.
Adopt hybrid schemes that combine classical and post-quantum algorithms, so you stay interoperable with partners and suppliers who haven't migrated yet.
No-regret moves are available today: TLS 1.2 to TLS 1.3 migration and enabling ML-KEM key exchange wherever your stack already supports it.
Identify where cryptography lives in your own landscape and across your supply chain, and which critical chains depend on suppliers being ready.
The transition is not just an IT project. It spans people, governance and purchasing. Ask suppliers for their roadmaps and put PQC requirements in contracts now.
We built an LLM-based agent framework that works with your organisation on PQC compliance. It integrates with your repositories on GitHub or any other host, scans your landscape and reports where you stand.
Unlike pattern-matching scanners, the agents understand context: how a key is used, which chain depends on it, and whether a finding actually matters. The result is not a pile of matches but a Crypto Bill of Materials you can plan a migration on.
Agents reason about cryptographic usage in any language, framework or configuration format. There are no per-language rule packs to maintain.
The framework installs and runs entirely inside your own infrastructure. Source code, keys and findings never leave your perimeter.
You decide what the agents may touch: read-only analysis per repository, or read/write capabilities for assisted remediation.
A full inventory across OS, middleware, networks, software, libraries, plugins and hardware components, with your critical chains identified.
Deprecated and quantum-vulnerable algorithms (RSA, ECDSA, DH), hardcoded keys, certificates and their expiry. Every finding is classified classical or quantum-safe.
Run the scan on demand or on a schedule. Each report tracks progress against the previous one, turning compliance into a continuous process.
Reads your estate in context, in any language or format, entirely inside your perimeter.
A full inventory of where cryptography lives, with critical chains identified.
Every algorithm, key and certificate marked classical or quantum-safe.
A prioritised, supplier-aware plan you can act on and re-run anytime.
Crypto agility built in: request, replace and roll over certificates and key material automatically as standards and lifetimes change.
Turn the inventory into a prioritised, supplier-aware migration plan: risk-based, value-based or outside-in.
Verify what actually ships, not just what source code intends, by surfacing vendor-supplied and compiled-in cryptography that repo scans can't see.
The same framework generalises to other scanning domains: security audits, bug detection, dependency health and beyond.
Eight steps, from knowledge and inventory to transition and governance. The approach follows what is used across Dutch government and the ETSI three-phase migration model.
Build PQC knowledge on your critical chains: algorithm response, resource usage, benchmarking.
Map cryptography across OS, middleware, networks, software, libraries, plugins and hardware. Establish critical chains.
Automate the crypto chain so certificates and key material can be replaced quickly, both now and at every migration that follows.
Surface supplier roadmaps and quantum-safe products. Put PQC requirements in tenders and contracts.
Determine which systems and processes are affected by the PQC transition, and in what order.
Risk-based, value-based or outside-in. Dependencies mapped, impact on operations assessed, planning set.
TLS 1.2 to TLS 1.3 migration. Enable ML-KEM key exchange wherever it is already possible.
Build cooperation with chain partners and government. Set up governance for a coordinated transition.
We write about the quantum transition as it develops. Two pieces worth starting with:
How we work with PCSI on the road to a quantum-resilient future, and what it means for organisations preparing today.
Read article →Where the quantum threat meets distributed ledgers, and how to think about resilience before Q-Day arrives.
Read article →See where your organisation stands. We run our framework against a repository of your choice, inside your own infrastructure, read-only, with no data leaving your perimeter. Afterwards we walk you through the crypto inventory and findings together.
The scan is free and works like an initial audit: no commitment and no preparation needed. Leave your details and we'll get in touch to set it up.
