TISAX – Information Security in the Automotive Industry


What is TISAX?

So far, information security in the automotive industry has been strongly influenced by individual approaches – that is about to change. Service providers and suppliers must regularly prove to their customers that they meet the high security requirements for data provided. So far, such assessments have been carried out mainly by the manufacturers themselves, which in the past repeatedly led to unnecessary multiplication. With TISAX (Trusted Information Security Assessment Exchange), there will be a joint assessment and exchange procedure in the future.


Are you a supplier or service provider for the automotive industry? If so, you need only one thing to assure customers that you are keeping their information secure – participation in the TISAX Exchange. All it takes is one assessment every 3 years.

The advantages of TISAX

  • Cross-company recognition of the assessment results among all TISAX participants
  • Greater confidence in certified service providers and suppliers
  • Avoids the need for multiple checks
  • Fewer misunderstandings due to the harmonized VDA-ISA test catalog
  • Mutual recognition in the TISAX network saves time and cost
  • Only one TISAX assessment every three years

How it works – Becoming a participant

Access to TISAX is via a subscriber registration, which takes place online on the TISAX portal. Registration is the prerequisite for being able to select a TISAX accredited audit service provider. Registered participants will receive a list of accredited providers from which they can freely choose. An organization may also register several locations and have a group assessment carried out. After an assessment by DQS based on VDA-ISA, information can be provided or obtained in TISAX.

Who is behind TISAX?

TISAX uses the ISA questionnaire compiled by the German Automotive Industry Association VDA based on essential aspects of ISO / IEC 27001. Recently, the VDA developed this into a common assessment and exchange procedure called TISAX, which is operated by ENX, an association of European car manufacturers, suppliers and associations.
