What We Do
CryptoNext Security is a European software vendor based in Paris, an industry leader in quantum-proof cryptography (PQC) solutions. Our vision and the solutions we are developing are designed to manage the complete lifecycle of post-quantum migration, including the phases of discovery, remediation, and management. Founded in 2019 after 20+ years of academic research within the prestigious INRIA, CNRS and Sorbonne University, CryptoNext Security is identified by Gartner as part of its Top 5 in PQC and is, to date, the first European company selected by NIST's NCCoE group dedicated to the best PQC migration practices. We are developing an integrated, quantum-safe remediation suite allowing for the automation of PQC migration for IT/OT systems, infrastructures and applications. Our objective is to help businesses and HW/SW vendors face the quantum threat in an efficient, agile and sustainable way.
