Post-Quantum Cryptography & Crypto‑Agility

Make your organisation quantum‑safe, before Q‑Day.

Quantum computers will break the encryption that protects today's data, transactions and identities. QuantumSafe helps you find your cryptography, prioritise the risks and migrate to post-quantum cryptography in a controlled way.

Mosca's inequality

Is your data already at risk?

Professor Michele Mosca's rule of thumb shows when you need to start. If the time your data must stay secret plus the time you need to migrate exceeds the time until the threat arrives, you are too late.

X + Y > Z

  • X, shelf-life: the number of years the information should be protected.
  • Y, migration time: the number of years needed to migrate your systems properly and safely to a quantum-safe solution.
  • Z, threat timeline: the number of years before relevant threat actors can break quantum-vulnerable systems.
For example: medical records, contracts, IP or state secrets.
Large organisations typically need many years.
Experts expect 2030–2040, roughly 4 to 14 years from now.

Post-quantum cryptography in a few minutes

What changes when quantum computers arrive, why "harvest now, decrypt later" makes this urgent, and what crypto-agility means for your organisation.

Regulation

The deadlines are already set

Governments and regulators are moving from guidance to timelines. Critical entities, financial institutions and public bodies are expected to act first.

2024

NIST publishes the first PQC standards: ML-KEM, ML-DSA and SLH-DSA.

2026

EU member states start the transition. The Dutch Wwke implements the EU CER directive.

2030

High-risk use cases quantum-safe. NIST proposes deprecating RSA and ECC.

2035

Migration as complete as feasible. Quantum-vulnerable algorithms disallowed.
