Tisax
On the request of some of the largest automotive manufactures a common assessment and exchange procedure, based on essential aspects of ISEO/EIC 27001, was developed: TISAX (Trusted Information Security Assessment Exchange). Service providers and suppliers must regularly prove to their customers that they meet the high security requirements for data provided.
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 catalogue.
- Mutual recognition in the TISAX network saves time and cost.
- Only one TISAX assessment every three years.

Becoming a Participant - Exchanging Information
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, like DQS. An organization may also register several locations and have a group assessment carried out. After an assessment based on VDA-ISA, information can be provided or obtained in TISAX.
