Post-quantum algorithms are standardised, but their size and computational cost reshape sovereign infrastructure. This guide quantifies the overhead and explains how to plan capacity before deployment.
A risk-tiered guide for financial sector CISOs on prioritising post-quantum cryptography migration, covering DORA obligations, ENISA 2030 deadlines, harvest-now-decrypt-later threats, and sovereign infrastructure controls.
RFC 9794 formalises terminology and construction rules for hybrid post-quantum cryptography. This guide explains how sovereign operators should deploy ML-KEM plus X25519 across TLS, SSH and email, manage certificate lifecycles, and satisfy...
QKD and post-quantum cryptography address different threat vectors. This article explains how EU-regulated organisations can combine both layers into a provable, audit-ready sovereign communications strategy.
A cryptographic inventory is the mandatory first step in any post-quantum migration programme. This guide explains how to build one, prioritise assets and satisfy NIS-2 and EU PQC requirements.
Industrial control systems face unique post-quantum migration challenges: legacy hardware, microsecond latency, and decades-long lifetimes. This guide shows sovereign operators how to prioritise and act now.
Migrating HSMs to post-quantum algorithms ML-KEM and ML-DSA is not a firmware update, it is a programme that touches key ceremonies, escrow policy, CA trust anchors and procurement strategy.
The EU NIS Cooperation Group's June 2025 PQC roadmap sets firm deadlines for critical infrastructure. This guide explains what compliance officers and CISOs must do before 2026 and 2030.
Current FIDO2 passkeys rely on elliptic-curve algorithms that a quantum computer will break. This guide explains the migration path to ML-DSA, hybrid signatures and sovereign-compatible hardware keys.
TLS 1.3 is the primary target for harvest-now-decrypt-later attacks. This article explains how ML-KEM hybrid key exchange, IETF drafts and the EU NIS PQC roadmap translate into concrete migration steps for regulated...
Migrating PKI to post-quantum algorithms is harder than upgrading session encryption. This guide covers composite, dual, and PQC-only certificates, EU regulatory deadlines, and concrete first steps for CISOs.
Cryptographic agility lets organisations swap algorithms centrally without touching every application. For sovereign infrastructure operators facing post-quantum deadlines, it is not optional.
NIST has finalised ML-KEM, ML-DSA and SLH-DSA as the first post-quantum cryptographic standards. This guide explains each algorithm, the compliance timeline, and a practical migration roadmap for government and regulated sectors.
Adversaries are collecting encrypted data today to decrypt it once quantum computers mature. For organisations holding data with a 10- or 20-year sensitivity horizon, the threat is not future — it is...
