SandGrain delivers CyberRock, a hybrid hardware-software security solution that embeds an immutable, globally unique ID inside every IoT device and pairs it with a secure cloud platform for real-time identity management. By replacing traditional, certificate-based approaches with a symmetric challenge-response scheme, the system offers post-quantum resilience while reducing total cost of ownership. The patented Root-of-Trust is pre-provisioned at manufacture, streamlining deployment for industrial, critical infrastructure, and aerospace & defense customers. CyberRock is already protecting devices in the field and is positioned for large-scale rollouts as new regulations such as the EU Cyber Resilience Act and NIS2 Directive raise security requirements. The company emphasizes compliance with emerging standards as a key competitive advantage. Recent funding will be used to accelerate scaling and meet growing market demand for economical, future-proof IoT security. No revenue or user figures were disclosed in the article.
