TISAX vs. ISO 27001: What IT managers in the automotive supply chain need to know

- Approximately 75% of controls overlap: If you already operate an ISO 27001-compliant ISMS, you've already covered most of the requirements of the automotive-specific audit standard – the remaining effort focuses on prototype protection, physical security, and the specific exchange process via the ENX portal.
- Two distinct outcomes: ISO 27001 culminates in an internationally recognized certificate. The automotive-specific audit standard does not issue a certificate, but rather a label that is stored in the ENX portal and can only be shared with authorized partners – public self-promotion with it is strictly forbidden.
- IT documentation is the common mandatory foundation: Both frameworks require complete, up-to-date documentation of IT assets, network structures, and authorization concepts. If you've properly established this once, you can use the same data foundation for both audit processes.
