What to Know Before Choosing a Safety RTOS

Choosing a safety RTOS can directly impact your certification timeline, development effort, and overall project risk.

In this video, we outline the key considerations engineers should understand before committing to a solution.

A structured approach to certification

SAFERTOS® is independently certified by TÜV SÜD to IEC 61508 (SIL 3) and ISO 26262 (ASIL D), and we continue to submit product variants to maintain alignment with these standards.

Alongside this, SAFERTOS® is delivered with a comprehensive Design Assurance Pack (DAP), giving you access to the full set of lifecycle documentation, safety analysis, and verification evidence needed to support certification activities.

Tailored to your exact environment

One of the key differences with SAFERTOS® is how it’s delivered.

Each variant is built and verified specifically for your chosen processor, compiler, and configuration. This level of detail ensures the RTOS behaves exactly as intended in your environment, one of the reasons SAFERTOS® has such a strong track record in safety-critical applications.

You also receive:

  • Full source code
  • A complete software test harness
  • User and safety manuals to guide integration

A familiar path from FreeRTOS

SAFERTOS® is based on the same functional model as FreeRTOS, making it a natural progression for teams already familiar with that environment.

This allows you to prototype using FreeRTOS, then transition into a safety-certified solution when you move into formal development, with guidance and documentation to support

Clear licensing and ongoing support

We keep the commercial side straightforward.

You’ll receive clear, upfront pricing and a defined licence agreement before development begins, along with 12 months of support and maintenance to help you through integration and certification.

The licence itself is royalty-free and perpetual, designed to minimise long-term cost and avoid unexpected restrictions as your project scales.

The best way to understand how SAFERTOS® fits your project is to evaluate it yourself.
