Post-Quantum Cryptography

Quantum computers threaten the public-key cryptography that secures most of today's communications. This section covers the threat model, the NIST-standardised algorithms, and how mid-market organisations should plan their transition.

Why this matters now

The risk is not only future decryption. Adversaries can capture encrypted traffic today and decrypt it once a capable quantum computer exists — the "harvest now, decrypt later" problem. For regulated data with a long confidentiality lifetime, the migration clock has already started.
