ISO/SAE 21434 Certification for Automotive Cybersecurity
ISO/SAE 21434 Certification for Connected Vehicle Cybersecurity and CSMS
ISO/SAE 21434 certification helps automotive organizations manage cyber risk across vehicle design, software, suppliers, and post-production operations. Accredify Global reviews your cybersecurity management system so OEMs, Tier 1 suppliers, and engineering teams can show disciplined control over connected vehicle threats and compliance expectations such as UN R155.
Where ISO/SAE 21434 Certification Is Used
Automotive programs use this standard when cybersecurity has to be proven from concept through end-of-life support.
Connected Vehicle Platforms
Telematics, infotainment, and remote services expose vehicles to cyber threats that need formal governance.
UN R155 CSMS Programs
OEMs and suppliers need a cybersecurity management system that supports vehicle type approval obligations.
Software-Defined Vehicle Releases
Continuous software updates require change control, testing, and release approval discipline.
Supplier ECU and Component Control
Tier 1 and Tier 2 suppliers must show traceable security requirements across hardware and embedded software.
Threat Analysis and Risk Assessment
Engineering teams need repeatable methods for identifying attack paths and prioritizing mitigation.
Incident Response and Vulnerability Handling
Automotive security teams need controlled processes for vulnerabilities, disclosures, and field issues.
How ISO/SAE 21434 Certification Works
The audit checks whether cybersecurity governance is built into the vehicle lifecycle, from concept and development through production and field operation.
- Phase 1: Scope review, vehicle program mapping, and cybersecurity policy review
- Phase 2: Stage 1 audit of CSMS documentation, supplier control, and risk methods
- Phase 3: Stage 2 audit of implementation, development controls, and evidence from active projects
- Phase 4: Certification decision and scope confirmation
- Phase 5: Surveillance audits to check sustained cybersecurity governance
Typical Timeline
- 6-8 weeks: programs with mature cybersecurity documentation and control owners
- 8-10 weeks: engineering teams formalizing CSMS requirements
- 10-12 weeks: multi-platform vehicle portfolios and supplier networks
