SandGrain is a Dutch deep-tech company specializing in hardware-rooted cybersecurity for connected and mission-critical systems. The company has a particular focus on the aerospace and defence sectors.
Its flagship CyberRock solution delivers immutable hardware identity, robust authentication, and secure lifecycle management for devices operating in complex, high-risk environments. The Zero Trust Architecture (ZTA) combines the CyberRock Trust Anchor IC with the CyberRock Platform, enabling trusted hardware and data streams, secure AI deployment, protected firmware and model updates, and seamless integration into both new and legacy defence equipment and infrastructures.
Engineered for the long operational lifecycles typical of defence platforms, CyberRock supports supply chain integrity, verifies component provenance to prevent counterfeits and backdoors, and provides post-quantum resilience against emerging threats. The solution embeds verifiable trust at every network node — from avionics and unmanned systems to field-deployed sensors and secure command-and-control networks — supporting secure-by-design architectures where trust begins at the hardware layer.
In an era of increasing regulatory requirements and geopolitical challenges, SandGrain helps defence organizations, prime contractors, and government entities strengthen security, traceability, operational resilience, and digital sovereignty. CyberRock supports compliance with frameworks and regulations such as the EU Cyber Resilience Act (CRA), NIS2, and CMMC.
Founded in 2019 in Eindhoven, the Netherlands, SandGrain combines expertise in semiconductors, embedded systems, cryptography, and cybersecurity to deliver the next generation of trusted, sovereign connected defence systems.
