ENX Vehicle Cyber Security Audit

ENX Vehicle Cyber Security Audit (VCS) is a standardized certification scheme developed by the ENX Association to assess and certify the cyber security maturity of automotive suppliers. It ensures your Cyber Security Management System (CSMS) aligns with ISO/SAE 21434 and supports compliance with UNECE UN R155. At DNV, we see ENX VCS as a strategic enabler—it not only helps you meet regulatory and customer requirements but also builds trust with OEMs, reduces audit duplication, and strengthens your market position.

While ISO/SAE 21434 assessments demonstrate alignment with cyber security engineering practices, ENX VCS goes a step further by providing a formal, industry-recognized certification. It uses a standardized audit framework governed by the ENX Association and is accepted by multiple OEMs as proof of CSMS compliance. ENX VCS also enables you to share your certification via the ENX Portal – reducing the need for repeated audits. Even if you’ve already been assessed for ISO/SAE 21434, ENX VCS gives you a recognized label that streamlines supplier qualification and enhances your credibility across the automotive ecosystem.

Before initiating an ENX VCS audit, your organization must have a valid TISAX® label for all relevant sites and a functioning CSMS aligned with ISO/SAE 21434. DNV can support you with readiness assessments, and training to ensure your systems and documentation are aligned with ENX VCS requirements before the formal audit begins.

The timeline can vary depending on your organization’s readiness, the scope of the audit, and the number of sites involved. Typically, the process—from registration and preparation to audit and certification—can take several weeks to a few months. DNV works closely with you to plan and execute the audit efficiently, minimizing disruption to your operations.
