SAFERTOS® is a functional safety, pre-certified, Real Time Operating System (RTOS) for embedded processors. It delivers top performance and pre-certified dependability, whilst utilising minimal resources.

  • Developed by WITTENSTEIN high integrity systems (WHIS), a FreeRTOS partner that specialises in safety
  • Available pre-certified to IEC 61508 SIL 3 and ISO 26262 ASILD by TÜV SÜD
  • Supports a wide range of international development standards
  • Based on the FreeRTOS functional model and therefore easy to migrate to
  • See the WHIS partial customer list
  • See Customer Reviews
SAFERTOS is delivered with a Design Assurance Pack (DAP) which contains every design artefact produced during the full development life cycle. The DAP ensures an easy route to achieving certification of SAFERTOS once integrated into a Safety Critical device.

SafeRTOS or FreeRTOS?

SAFERTOS is based on the functional model of the FreeRTOS kernel, however, it is not the FreeRTOS kernel. It has been completely re-designed by a team of functional safety experts at WHIS. Their engineers took the FreeRTOS kernel functional model, subjected it to a full HAZOP, and generated a set of safety requirements. The resulting functional and safety requirements sets were put through an IEC 61508-3 SIL 3 development life cycle, creating the SAFERTOS code base and DAP.

Easier Certification

Certifying SAFERTOS integrated within a product is a simple and hassle-free process.

Contained within the Design Assurance Pack, or DAP, (which is included with SAFERTOS purchases) is the all-important Safety Manual. The Safety Manual explains exactly how to install and integrate SAFERTOS into your development environment. Following the concise instructions will also generate the evidence required by your auditors to confirm the process has been followed correctly. This removes the need for re-testing on your target hardware, and provides a solid dependable platform for your development. The DAP contains all the Planning, Design and Verification artefacts, and is specific to the selected Processor/Compiler combination.
