Device Security Booster (DSB) is an IoT Software Update Management (SUM) platform designed to help organizations manage firmware and software updates across large IoT/OT device fleets throughout the entire product lifecycle. The platform addresses regulatory compliance requirements such as the Cyber Resilience Act (CRA), NIS 2, IEC 62443, and ISO 27001 by enabling security-by-design practices on connected devices. Key functional areas include: Device Management: Connected devices are organized into groups, with real-time health status monitoring. Operators can block suspicious devices at any time. Firmware Management: Firmware files are scanned, organized, and stored on a peer-to-peer file server. Rollout Management: Over-the-Air (OTA) software updates can be distributed to registered devices. Supported RF protocols include LoRaWAN, 5G, NB-IoT, WLAN, LAN, and Lightweight M2M (LwM2M). The platform provides dashboards for monitoring device status and managing rollouts. It targets industries including industrial automation, automotive OT, critical infrastructure, government/defense, and space/aerospace. Additional services offered alongside the product include risk management, enterprise engineering support, compliance regulatory readiness consulting, and deployment services.
