Trusted Information Security Assessment Exchange (TISAX) is an assessment and exchange mechanism for information security in the automotive industry. The TISAX certification confirms that a company’s information security management system complies with defined security levels and allows sharing of assessment results across a designated platform.
The Original Equipment Manufacturer (OEM) collaborates with multiple companies across the value chain for the design, manufacturing, and distribution of their vehicles. To facilitate collaboration, the OEM frequently shares confidential information, such as a prototype design, with the supplier base. If valuable data is not effectively protected, the exchanges along the supply chain may cause losses, manipulations or even theft of trade secrets. Consequently, OEMs will want to ensure that their suppliers and partners, including marketing and sales organisations, have a solid information security management system in place before they are contracted.
There are three TISAX 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.
