Why now?

The threat is already here

Quantum computing will break today's encryption. The question isn't if - it's when. And adversaries aren't waiting.

Harvest‑Now‑Decrypt‑Later

HNDL risk makes long‑lived data exposed today. Adversaries harvest encrypted traffic now, waiting for quantum capability to break it.

Expanding attack surface

Networks are more dynamic - SD‑WAN, 5G, edge - while endpoints multiply and sprawl beyond traditional perimeters.

Compliance pressure

Sovereignty requirements are rising fast across the UK, EU, and US, with tight PQC migration timelines.

Five pillars of quantum‑safe security

Confidential Computing

Run NetworkSecure inside Intel® TDX trust domains. Keys are generated inside the enclave and rotated frequently - so data stays confidential in use and in transit, even on shared infrastructure.

Data Sovereignty

Keep encryption keys under your control while operating in the cloud. Enforce end‑to‑end encryption between trust domains to protect workloads, even from Cloud Service Providers.

Encryption Intelligence

Build a complete crypto inventory, pinpoint weaknesses, and create a PQC‑aligned migration plan - then monitor continuously.

5G Secure Networks

Deliver quantum-safe, zero-trust backhaul encryption with high-frequency key rotation, eliminating PKI dependencies and protecting infrastructure without downtime.

Post‑Quantum Cryptography

Securing now means agility for tomorrow. Use a hybrid, standards‑aligned approach that protects long‑lived data while you migrate.

Robust Protection against 21st Century Security Challenges

Arqit’s solutions can work for you if you are:

Handling long-lived data (e.g. trade secrets, health information, national security information)
Expanding a network, especially into areas which will have long-lived fixed infrastructure, e.g. at the edge
Where infrastructure and endpoints are hard to manage, e.g. because
- it’s difficult to access physically
- has restrictive access controls
- needs manual key management (e.g. PSKs)
Required to have strong adherence to standards and regulation
