What is a TISAX audit?

The TISAX (Trusted Information Security Assessment Exchange) audit is a comprehensive process for assessing information security, personal data protection, and the information security management system within an organization, carried out in accordance with the requirements of the automotive industry. It helps companies – especially suppliers – enhance data protection, reduce operational risks, and meet the demands set by OEM and Tier 1 partners.

Implementation of the TISAX standard – the key to information security

A TISAX audit is not just a formal assessment of compliance with industry requirements—it is a strategic tool for building a company’s credibility in the eyes of partners in the automotive sector. In today’s environment, where data protection and digital resilience are increasingly critical, having proof of TISAX compliance has become a key element of competitive advantage. For many manufacturers and suppliers, a TISAX certificate is a prerequisite for initiating cooperation. Conducting the audit allows companies to identify weaknesses in their security systems, improve information management processes, and prepare for the demands of future contracts. As a result, TISAX not only enhances information protection but also opens the door to new business opportunities.

TISAX is an assessment and information exchange mechanism within the automotive industry that ensures effective information security throughout the supply chain. It is based on the VDA ISA catalog, which outlines requirements for an information security management system aligned with ISO 27001 standards.


Who is TISAX for?

The TISAX standard was developed by the German Association of the Automotive Industry (VDA – Verband der Automobilindustrie) and is required by the largest car manufacturers. A TISAX audit is essential for companies that:

process confidential technical data from partners,

provide services or production for the automotive industry,

plan to start working with major automotive corporations.

This also applies to parts suppliers, raw material providers, service vendors, research institutes, and other participants in the supply chain. Through the ENX Association platform, all business partners who handle confidential information and wish to share audit results can become TISAX participants. TISAX labels confirm that an organization meets the information security requirements of the automotive sector.
