Trusted Information Security Assessment Exchange (TISAX)

Information security for the automotive industry

What is TISAX?

Many suppliers and service providers in the automotive industry process highly sensitive information from their clients. Given this, clients regularly request evidence of compliance with stringent information security requirements. In most cases, such evidence is provided with the help of Information Security Assessment (ISA) criteria catalogues developed by the German Association of the Automotive Industry (VDA). However, as individual manufacturers have conducted these ISAs for their suppliers independently so far, many suppliers have had to undergo the same assessment several times.

To reduce these unnecessary efforts and expenses, 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. Organisations can keep control over their results at all times – this information can only be exchanged and shared after prior approval. Assessments would be conducted at 3 levels and would be completed in 6 steps.

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.

The assessments are carried out in 6 steps as mentioned below:

STEP 1: CLASSIFICATION

In step 1 suppliers are classified by an OEM/client depending on the sensitivity of the data involved.

STEP 2: REGISTRATION
In the next step they register with ENX, including their scope number.

STEP 3: ASSESSMENT
TÜV SÜD carries out the assessment in line with the requested level.

STEP 4: REPORT
The assessed company receives the report from the TÜV SÜD auditors.

STEP 5: ELIMINATION OF VULNERABILITIES
The assessed company eliminates identified vulnerabilities.

STEP 6: UPLOADING OF REPORT
The completed report is uploaded to the exchange platform. Exchange of these summaries is only possible among registered participants and only after the assessed company has expressly released the results to the company that places the request.
