Simple, Secure, Now

World class, quantum-secure ecosystems

We are the only source of usable quantum-safe solutions with our range of available software products. Our products combine to deliver a safe, quantum-secure ecosystem, protecting your data and improving customer experience.

PQ Chat

Secure, seamless, end-to-end. The world’s first quantum-safe, secure, end-to-end encrypted messaging app.

Hybrid PQ VPN

Secure, simple, future proof. our Hybrid PQ VPN secures data-in-transit from traditional and quantum attack.

Nomidio Identity

Nomidio is our quantum-ready multi-factor biometric identity system for secure passwordless sign-in

Leading in quantum-safe standards

 We were the first company to begin solving the post-quantum encryption challenge back in 2009 and we’ve been involved in major community initiatives ever since.

Our team of world-leading cryptographers and engineers authored the only remaining finalist algorithm in the code-based category of the NIST Post-Quantum Cryptography Standardisation competition, which is defining the future global standard of public-key cryptography.

We are also the authors of the Internet Engineering Taskforce (IETF) standards for a post quantum Virtual Private Network and we’ve since developed this as a product, which is in use today (and being trialed by NATO).

As the only company building a range of usable quantum-safe software products that combine to deliver a quantum-safe ecosystem, we’re unique in the industry. This ecosystem protects data from the moment it is created, when it is stored and as it is transferred, as well as securing organisations from adjacent risks like quantum identity attacks.

Others claim it, we’re doing it

 We have been working to protect the world from the risk of quantum attack since 2009 and our committed team has been involved with many of the first real-world quantum-safe projects.

No matter the industry you operate in, we can help you to deliver solutions that protect your data and assets from quantum attack. Anywhere that your organisation relies on cryptography provides an opportunity to prepare for the quantum era.

Our encryption and products are used in live environments today across financial services, national security & defence and critical national infrastructure. Our customers include:

Useable quantum-safe products

Our products are designed to work with existing infrastructure offering backwards compatibility ensuring the migration to quantum-safe doesn’t impact day-to-day operations.

We are committed to the principle of ‘crypto-agility’, so our products are designed to work with any quantum-safe encryption algorithm – not just Post-Quantum’s own R&D.

Our products are also hybrid, so both classical and post-quantum encryption can be combined to protect against threats irrespective of the computer used by an adversary.
