Post-quantum cryptography is not a future problem.

Why we exist

The cryptographic foundations of the modern internet — RSA, ECDH, ECDSA — rest on mathematical problems that a large-scale quantum computer will solve in polynomial time. That computer does not exist yet at the scale required to break production key sizes. But serious nation-state, academic, and commercial investment means long-lived-data planning must treat cryptographically relevant quantum computers as a present risk. This site uses a 2029 to 2033 planning scenario for migration sequencing. The time to migrate is not when that window opens. It is now.

Quanten Security focuses on organisations most exposed to long-lived confidentiality risk: critical infrastructure operators, financial institutions, government agencies, defence contractors, and sovereign-cloud providers. The work is grounded in the NIST-standardised algorithms defined by FIPS 203, 204, and 205, with operational evidence that sensitive environments can review before deployment.

The harvest-now-decrypt-later imperative

The most urgent dimension of the quantum threat is not the future attack. It is the present collection. Nation-state signals intelligence services with access to internet exchange points are recording encrypted network traffic today — at scale, systematically, and with patience. The stored ciphertext will be decrypted once a sufficiently powerful quantum computer is available. Any data encrypted today whose confidentiality requirement extends beyond 2029 is already at risk.

For a financial institution retaining transaction records for 10 years, a healthcare provider holding patient histories for 30 years, or a government agency handling intelligence that must remain secret for decades, the migration obligation is not aspirational — it is immediate. Our mission is to compress the time between recognising this obligation and acting on it, by providing the tools, expertise, and integration support to make PQC migration operationally tractable.

Who we serve

Our clients are organisations for whom cryptographic failure is not a recoverable IT incident. Energy grid operators whose SCADA authentication protects physical infrastructure. Banks whose signing chains underpin inter-bank settlement. Government agencies whose classified archives must remain secret across political cycles. Defence contractors whose intellectual property is targeted by state-level collection programmes. Sovereign cloud providers whose entire value proposition rests on demonstrable control over key material.

These organisations need more than a vendor selling an algorithm. They need a partner who will sit with their security engineering team, map their specific exposure, and help them make the right sequencing decisions across a multi-year migration. That is what Quanten Security provides. Start the conversation.
