An assessment and exchange mechanism for information security in the automotive industry, based on the VDA ISA catalogue.
TISAX (Trusted Information Security Assessment Exchange) is the automotive sector's standard for verifying information security. It is built on the VDA ISA questionnaire, which derives from ISO/IEC 27001 with industry-specific additions for prototype protection and data handling.
Assessments are carried out by accredited providers, and results are shared through the ENX platform so that manufacturers and suppliers can rely on a common, reusable assessment rather than auditing each other repeatedly.
