CryptoNext Security Tech Stack

Post-quantum cryptography and crypto-agility management platform

Computer and Network Security Paris, Paris 11–50 employees Founded 2019 Privately Held

CryptoNext Security builds software to help organizations transition to quantum-resistant cryptography and manage cryptographic risk across their infrastructure. The stack—mbedTLS, Kafka, PostgreSQL, Elasticsearch, and Kubernetes—reflects a data-intensive observability platform (Compass) designed to ingest, track, and govern cryptographic assets at scale. Hiring is engineering-heavy (7 of 11 open roles) with senior/lead distribution, suggesting they're scaling both product depth and deployment complexity in finance, defense, and industrial sectors.
