Post-quantum security migration

We find where your systems rely on encryption that future quantum computers could break, then migrate them to the post-quantum standards NIST published in 2024. The work protects long-lived data today against "harvest now, decrypt later" attacks.

Why act now

Attackers can record encrypted traffic today and decrypt it once large quantum computers exist. Data that must stay secret for years, such as health, financial and citizen records, is already at risk.

Our approach

We build a cryptographic inventory, rank systems by risk, and introduce crypto-agility so algorithms can be swapped without rewrites. Migration uses the NIST standards ML-KEM (FIPS 203) and ML-DSA (FIPS 204), often in hybrid mode alongside today’s algorithms.

What we do

Cryptographic inventory

Automated discovery of keys, certificates and algorithms.

Risk prioritisation

Ranking by data lifetime and exposure.

Crypto-agility

Abstractions that make future algorithm changes cheap.

PQC migration

Hybrid TLS, VPN and code-signing upgrades.

How we deliver it

  1. Discover

    Scan code, infrastructure and vendors for cryptography.

  2. Prioritise

    Rank systems by data lifetime and exposure.

  3. Pilot

    Hybrid post-quantum TLS on one critical service.

  4. Migrate

    Roll out in waves with performance testing.

Questions people ask

What is post-quantum cryptography?

Post-quantum cryptography is encryption designed to resist attacks from both classical and quantum computers. It runs on today’s hardware, so it can be deployed now.

When should we start migrating to post-quantum cryptography?

Now, if you hold data that must stay confidential for more than five to ten years. Inventory and crypto-agility work can begin immediately and takes time in large estates.
