Security First
We prioritise security over convenience. Our conservative cryptographic approach values proven security over untested innovation.
Pioneering Quantum-Safe Security Since 2009
The first company founded with sole focus on post-quantum cryptography. For 15 years, we have been developing the technologies, standards, and expertise that organisations worldwide now rely upon.
About Us
Our Vision
Post-Quantum was established in 2009 when quantum computing threats were still dismissed as distant theoretical concerns. Our vision was clear: quantum threats require quantum solutions. Not in 10 years. Today.
Our Mission: Protecting the world's information against current and future threats through quantum-safe cryptographic innovation.
Our Approach: We combine pioneering research with real-world deployment. Our solutions are production-ready technologies protecting NATO communications and critical infrastructure worldwide.
