QNX OS for Safety
The embedded operating system certified for IEC 61508 SIL3, ISO 26262 ASIL D, and IEC 62304 Class C—purpose-built for safety-critical embedded systems.
Real-Time OS for Safety-Critical Applications
QNX OS for Safety streamlines your functional safety certifications with a pre-certified microkernel RTOS and toolchains, ready for use in industries such as medical, industrial automation, automotive, rail, and aerospace.
Includes all required safety documentation and certification artifacts.
QNX Accelerate in the Cloud
Develop QNX OS for Safety-based systems in the cloud with QNX Accelerate—enabling faster collaboration, agile development, and reduced time-to-market for mission-critical embedded solutions.
Streamline Safety Certification
- Certified to: IEC 61508 SIL 3, ISO 26262 ASIL D, IEC 62304 Class C, EN 50128 SIL 4, EN 50657 SIL 4
- Toolchains qualified to ISO 26262 and IEC 61508 TCL3/T3
- Certified C++ library add-on for ASIL B/D use
- Use as Safety Element out of Context (SEooC)
Protect Critical System Functionality
Built on the proven QNX Neutrino microkernel RTOS, QNX OS for Safety ensures robust fault isolation and temporal/spatial protection, guarding the system against internal and external faults.
Certify Your Code, Not Your Toolchains
With pre-certified OS and toolchains, you only need to certify your application code—not the OS or toolchain—greatly reducing certification scope and effort.
Familiar Development Environment
Fully API-compatible with QNX Neutrino RTOS and POSIX. Use your existing knowledge and tools, including QNX Momentics Tool Suite, to build both safety and non-safety applications on the same platform.
Safety-Certified Add-Ons
QNX Filesystem for Safety (QFS)
Read-only, POSIX-compliant filesystem certified to ISO 26262 ASIL B. Verifies integrity of contents at runtime and helps detect corruption. Works alongside other file systems and integrates with Trusted Disk and Pathtrust.
QNX Black Channel Communications Technology
Certified to ISO 26262 ASIL D. Ensures reliable and safety-compliant data transmission by following the Black Channel approach defined in IEC 61508, eliminating the need for a certified communication stack.
