Creating a safer, greener, more secure future.


SAFERTOS® CORE is the RTOS for embedded systems where safety needs to be considered, or designed-in for future consideration. It is ideal for projects where full safety certification/ documentation is not required, or at least not required at the start of a long safety development life cycle. SAFERTOS® CORE provides the complete functionality and API of SAFERTOS®.

SAFERTOS® CORE is ideal for companies who are developing products that:

  • Need to consider safety but don’t require full certification
  • May require certification in the future, and want to future proof their designs
  • Require a robust, highly deterministic RTOS, incorporating key safety features
  • Are starting lengthy development projects where certification evidence/documentation is not required at the start of the project
