Our flagship program, delivered directly as an approved SGS-TÜV Saar partner. We systematically simplify the 10-part structure of the master standard so working engineers can apply it on real hardware — with practical guidance on risk assessment, Safety Integrity Level (SIL) determination, and software safety requirement validation.
Navigate the 10-part structure of IEC 61508 with confidence
Run risk assessments and determine the correct Safety Integrity Level (SIL)
Specify and validate software safety requirements
Build audit-ready evidence that satisfies third-party assessors
A structured path from fundamentals to audit-ready evidence. Expand any module to see its lessons.
