Cryptography and cyber threat intelligence for government and enterprise security

Computer and Network Security Torino, Piemonte 201–500 employees Privately Held

Telsy develops proprietary encryption and cybersecurity solutions for government and institutional buyers, with a focus on cryptographic foundations and threat intelligence. The tech stack—C/C++, Linux, embedded RTOS, and Kubernetes—reflects a hardware-capable security vendor building from first principles rather than wrapping commercial libraries. Recent acquisitions of quantum key distribution (2021) and threat intelligence (2023) capabilities signal a deliberate expansion from pure crypto into a full defensive stack.
