Why the quantum encryption threat demands action now
Harvest Now, Decrypt Later (HNDL): the quantum threat already targeting UK organisations
Adversaries do not need quantum computers to start the attack. They are capturing encrypted data now and storing it until decryption becomes viable. Legal, financial, healthcare, and government data transmitted today is at risk of future exposure.
NIST published its first post-quantum cryptographic standards in 2024. The NCSC has issued migration guidance for UK regulated organisations. The window for a structured, managed response is open. It will not stay open indefinitely.
- NIST FIPS 203, 204, and 205 published in 2024, establishing the algorithms that will underpin regulatory migration timelines.
- Y2Q probability estimated at 50:50 by 2031 by Dr Michele Mosca.
- NATO-approved supplier addresses both modern and legacy infrastructure.
Digital quantum key distribution for enterprise IP networks
D-QKD: quantum-safe key distribution, no hardware required
Traditional key exchange sends cryptographic keys over the same network path as your data. Capture the traffic and you capture the keys. D-QKD eliminates this by deriving keys independently at each endpoint using Quantropi’s Quantum Permutation Pad technology. Keys are never transmitted over the data path.
Runs in software over any IP network. No dark fibre. No distance limitations. Benchmarked by Deutsche Telekom at over 250x faster than photonic QKD.
- Supports ETSI GS QKD 014.
- Native integration with Cisco, Palo Alto Networks, Juniper, Fortinet, and Ciena.
- Built for financial services, legal, healthcare, public sector, and multi-site enterprises.
Post-quantum protection for legacy systems and OT environments
Quantum-safe forward proxy: protecting the systems you cannot re-engineer
Not every system in your estate can be updated. OT devices, fixed-firmware appliances, clinical systems, and legacy financial platforms cannot natively adopt post-quantum cryptography. The quantum-safe forward proxy sits in front of these systems, re-encrypting outbound traffic using quantum-safe algorithms before it crosses untrusted networks. The underlying device requires no modification.
No rip-and-replace. No downtime. Harvest Now, Decrypt Later (HNDL) exposure closed off at the boundary.
- Powered by Quantropi’s TrUE suite: MASQ, QEEP, and SEQUR.
- Built for NHS Trusts, manufacturing, utilities, critical national infrastructure, and IBM Power platforms.
