Trusted Information Security Assessment Exchange (TISAX)

Many suppliers and service providers in the automotive industry process highly sensitive information from their clients. Given this, their clients regularly request evidence of compliance with stringent information security requirements. In most cases, such evidence is provided with the help of the Information Security Assessment (ISA) criteria catalogues developed by the German Association of the Automotive Industry (VDA). TÜV SÜD is currently undergoing the accreditation process and is allowed to carry out TISAX assessments.


TISAX participants using the platform can:

  • Commission accredited service providers to carry out assessments
  • Share the results of completed assessments with other participants
  • View the results of other participants

There are three levels of assessment - 

Level 1: Standard suppliers only need to complete the ISA questionnaire and publish this self-assessment in TISAX. 

Level 2: In case of more complex suppliers, the self-assessment will be followed by random plausibility checks by telephone by an approved audit provider.

Level 3: Suppliers who handle highly sensitive external data undergo on-site inspection by an approved audit provider based on their self-assessment.
