ISO 27001 TISAX

TISAX (Trusted Information Security Assessment Exchange) is the established industry standard of the automotive sector for information security assessments and forms the foundation for trusted business relationships along the entire automotive supply chain. Based on ISO 27001 and the VDA ISA catalogue, TISAX enables the standardised and efficient exchange of security assessments between OEMs and suppliers.
