Post-Quantum Cryptography
Quantum computers capable of breaking RSA and elliptic curve cryptography are no longer science fiction. They are an engineering timeline. Use qubion to find PQC vendors and solutions that can guide your UK enterprise through readiness, migration, and crypto agility.
The quantum threat to today's cryptography
Harvest now, decrypt later
Adversaries are already capturing encrypted traffic and archives. The moment a cryptographically relevant quantum computer exists, today's secrets become tomorrow's leaks.
The window is shorter than it looks
Industry consensus places quantum risk between 2030 and 2035. Migrating a global enterprise PKI typically takes five to ten years, so the maths does not favour waiting.
Regulators are moving
NCSC, CISA and the EU all expect PQC transition plans. Financial services, healthcare and critical national infrastructure will be first to face mandates.
Match with PQC vendors
qubion is not a consultancy. We are the strategy platform and marketplace that connects your enterprise with specialist vendors who deliver PQC readiness assessments, migration tools, and managed crypto services.
Browse the marketplace
Compare PQC vendors, tools, and service providers in one place. Filter by capability, sector, and compliance need.
Shortlist by readiness
Use your qubion readiness profile to identify which vendor solutions align with your current maturity and migration priorities.
Connect directly
Request introductions, demos, and proposals from matched vendors through the platform, with no obligation to buy.
The algorithms to migrate to
In August 2024, NIST finalised the first post-quantum standards. These are the building blocks of the next decade of internet security.
ML-KEM (Kyber)
Key encapsulation. Replaces RSA and ECDH for establishing shared session keys.
ML-DSA (Dilithium)
Digital signatures. Replaces RSA and ECDSA for general purpose signing.
SLH-DSA (SPHINCS+)
Stateless hash based signatures. A conservative backup for long lived root signing.
A four-phase migration
Specialist vendors on the qubion marketplace use this structured approach to compress a multi-year PQC programme into an evidence-led roadmap your CISO and board can defend.
Discover
Inventory every cryptographic asset across TLS endpoints, signing keys, VPNs, HSMs, code signing chains, embedded firmware and archived data. You cannot migrate what you cannot see.
Prioritise
Rank assets by data lifetime and exposure. Long lived secrets such as medical records, IP and state communications are the harvest now, decrypt later targets and must move first.
Pilot
Run hybrid classical plus PQC handshakes (for example, X25519 with ML-KEM-768) against non critical workloads. Measure latency, payload size and operational impact before broad rollout.
Migrate
Replace RSA and ECC with NIST standardised algorithms. Build crypto agility into protocols and certificate authorities so the next algorithm change costs days, not years.
