Secure Boot & Signed Firmware
A chain of trust from ROM to application, so devices only run software you signed. Ready for the EU Cyber Resilience Act.
Readiness for devices already in the field
Recalls or hardware changes in field migration
Fleet monitoring and support
Secure OTA releases
The problem
Without secure boot and signed updates, a single compromised device or update server can take over a fleet. The CRA makes these controls a market requirement in the EU.
Unsigned software runs
Without secure boot, anyone with access can run their own code.
Weak key management
Keys on developer laptops put the whole fleet at risk.
CRA requirements
EU market access now depends on security by design and update obligations.
