Who We Are

CryptoNext Security is a start-up based in Paris, founded in 2019, following more than 20 years of academic research.

We specialize in quantum computer-resistant cryptography (PQC: post-quantum cryptography) and offer our "Quantum Safe Remediation Suite" software suite, including our world-renowned Quantum Safe Library (C-QSL) featuring the latest NIST algorithms. Our solutions help enterprises and integrators transition to the post-quantum cybersecurity era.

Recognized as a leader in post-quantum cryptography, CryptoNext was highlighted in Gartner's 2021 report and received the Innovation Prize at "Les Assises 2022." A proud member of Campus Cyber, Hexatrust, and Systematic, we are also collaborators with the US National Cryptography Center of Excellence (NCCoE).

At CryptoNext, we are a close-knit team driven by innovation, trust, and a shared commitment to solving complex challenges.
