SandGrain B.V.

SandGrain is a Dutch scale-up founded in 2019, specializing in IoT cybersecurity solutions for connected devices across sectors like automotive, industrial IoT, critical infrastructure, and aerospace & defense. Our flagship CyberRock platform combines a secure cloud infrastructure with immutable hardware tokens—hard-coded ICs providing post-quantum-resilient authentication. This enables real-time verification at scale, eliminating provisioning and certificate management while ensuring trusted identities, tamper-proof lifecycle assurance, and compliance with regulations like NIS2 and CRA. With €13.5M in Series A funding raised in December 2025, SandGrain empowers secure-by-design systems for sovereign data protection and smart supply chains.
