TISAX (Trusted Information Security Assessment Exchange) is a standardized information security assessment and certification program designed specifically for the automotive industry. It was initiated by the German Association of the Automotive Industry (VDA) to help automotive companies and their suppliers ensure the protection of sensitive information and intellectual property.

TISAX assessments are based on the VDA ISA (Information Security Assessment) catalog, which is derived from the ISO/IEC 27001 standard for information security management systems. TISAX enables automotive companies and suppliers to demonstrate their adherence to industry-specific information security requirements and establish a common level of trust throughout the supply chain. It reduces the need for multiple audits by allowing certified organizations to share their TISAX assessment results with other participating companies.

TISAX certification is often a requirement for companies looking to work with major automotive manufacturers, as it ensures a consistent level of information security throughout the supply chain. The TISAX program is managed by the non-profit organization ENX Association, which also accredits the audit providers that conduct the TISAX assessments.
