Products & Solutions
CryptoNext COMPASS
A cryptographic asset discovery and analytics suite that gives organisations full visibility into the encryption used across their IT systems. COMPASS Analytics aggregates data from heterogeneous sources into a centralised inventory in CBOM format, with compliance reporting and role-based access. COMPASS Network Probe passively monitors traffic in real time, analysing TLS, SSH and ISAKMP protocols at up to 1 Gbps throughput across 100+ IT/OT protocols.
CryptoNext Toolbox
A PQC evaluation platform that lets teams test their systems under post-quantum conditions before committing to a migration. Supports custom prototyping for specific business scenarios, helping organisations understand the operational impact of switching to quantum-safe algorithms.
CryptoNext Remediation
A post-quantum SDK that replaces vulnerable cryptographic components with NIST-validated quantum-safe algorithms. Designed to work in constrained environments as well as standard IT infrastructure, it enables organisations to implement long-term quantum-resistant protection across their systems.
CryptoNext Captain
A crypto-agility management platform that centralises cryptographic policy governance across an organisation. Enables security teams to automate policy enforcement and adapt rapidly to evolving PQC standards without manually reconfiguring distributed cryptographic infrastructure.
About
CryptoNext Security develops software that helps organisations discover, evaluate and deploy post-quantum cryptography (PQC), protecting IT and OT infrastructure against the threat posed by quantum computers to current encryption standards. Founded in 2019 as a spin-off from INRIA, CNRS and Sorbonne University, the company is headquartered in Paris and draws on more than 25 years of academic PQC research.
