The Netherlands
SandGrain B.V., founded in 2019 in The Netherlands, is making strides in the domain of IoT cybersecurity with its robust solutions tailor-made for connected devices across critical sectors. The company's motto, "Post Quantum (I)IoT Security made Simple," underscores its mission to simplify security in an increasingly connected world.
The central offering from SandGrain is its CyberRock platform, which leverages a combination of secure cloud infrastructure and immutably hard-coded IC tokens for authentication resilient to quantum computing threats. This innovative technology streamlines real-time verification processes, eliminates cumbersome certificate management, and enhances security by ensuring tamper-proof lifecycles. Furthermore, it aligns with regulatory frameworks such as NIS2 and CRA.
After raising €13.5M in their Series A funding round in December 2025 and a €2.00M Seed Round investment earlier from DeepTechXL, SandGrain is well-equipped to further its mission of empowering secure-by-design systems, vital for sovereign data protection and smart supply chains.
