Trusted Information Security Assessment Exchange (TISAX)

Information security for the automotive industry

In early 2017 VDA established TISAX (Trusted Information Security Assessment Exchange), a new assessment and exchange mechanism. The dedicated TISAX online platform is designed to support cross-company recognition of information security assessments in the automotive industry. By sharing their ISA results online on TISAX, companies enable OEMs to verify for themselves whether a service provider or supplier has already successfully completed the assessment. In addition, TISAX can be used to commission audit providers such as TÜV SÜD to carry out an assessment. 

Your Benefits at a Glance  

  • Assessments will be performed only by local experts
  • No duplication or multiplication of assessments
  • Major time and cost savings based on cross-company recognition of assessments and information 
  • Trust in assessed companies

TISAX Assessment Services from TÜV SÜD

TÜV SÜD is currently undergoing the accreditation process and is allowed to carry out TISAX assessments. 

There are three assessment levels:

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.
