Specialist practice

Post-quantum security

Quantum computers will break today's encryption — and attackers are already harvesting your traffic to decrypt later. We deploy next-generation quantum-safe TLS, with automatic fallback to today's standards so nothing breaks along the way.

The clock is already ticking

Encrypted today doesn't mean private tomorrow.

Adversaries are recording encrypted traffic now to decrypt it once a quantum computer can break RSA and elliptic-curve cryptography. Any data with a long shelf life — health, financial, legal, government — is effectively exposed today. Migrating early, with hybrid TLS that falls back cleanly, is the only safe answer.

What we deliver

Quantum-safe, without the disruption

The full migration — from cryptographic inventory to hybrid TLS in production — engineered so security goes up and nothing else goes down.

Hybrid quantum TLS

TLS 1.3 with a hybrid key exchange — a classical curve combined with ML-KEM (NIST FIPS 203). The session is safe as long as either half holds, so you are never worse off than today.

Graceful fallback & crypto-agility

Modern clients negotiate the quantum-safe suite; legacy clients fall back to classical TLS 1.3 automatically. Algorithms stay pluggable so they can be rotated as standards evolve.

Cryptographic inventory & risk

We map every place classical crypto is used and flag the data with long confidentiality lifetimes — the assets most exposed to harvest-now-decrypt-later.

PQ-ready PKI & certificates

A migration path for certificates and signatures to ML-DSA (FIPS 204) and SLH-DSA (FIPS 205), accounting for larger keys and handshake sizes.

Edge-to-mesh rollout

Hybrid TLS deployed across load balancers, API gateways, service mesh and mTLS between services — quantum-safe everywhere, not just the front door.

Interop & compliance

Fallback and interoperability testing across your real client base, with controls mapped to CNSA 2.0, NSM-10 and NIST migration guidance.

How it works

One handshake, two safe outcomes

Every connection negotiates the strongest cryptography both sides support — quantum-safe where possible, a strong classical baseline where not.

Our approach

Hybrid by design — so you're never worse off.

A hybrid suite combines a proven classical algorithm with a post-quantum one. An attacker has to break both to win — so you gain quantum resistance without betting everything on brand-new math. And because the architecture is crypto-agile, swapping algorithms later is a configuration change, not a re-platform.

  • Hybrid by default — classical security preserved alongside post-quantum
  • Crypto-agile architecture so algorithms can be swapped, not re-platformed
  • Standards-based on NIST FIPS 203 / 204 / 205 — no proprietary crypto
  • Graceful fallback that never breaks your existing clients
Today — RSA / ECC, harvestable now and breakable later
Hybrid — classical + ML-KEM, safe if either half holds
Tomorrow — rotate algorithms as standards evolve

Who needs this

If your data must stay secret for years, start now

The longer your data has to stay confidential, the more urgent the migration — because the recording is already happening.

Healthcare

Patient records that must stay confidential for decades — exactly the data harvest-now-decrypt-later targets.

Financial services

Transactions, contracts and client data with long regulatory retention and high-value secrecy.

Government & defense

Classified and sovereign data where CNSA 2.0 and NSM-10 migration timelines are already in motion.

Critical infrastructure

Long-lived industrial and IoT systems that are hard to patch and must outlast the quantum transition.

Start your post-quantum migration

We'll inventory your cryptography, prioritise what's most exposed, and roll out quantum-safe TLS with a fallback path that keeps every client connected.
