With TISAX (Trusted Information Security Assessment Exchange), the ENX Association supports the joint acceptance of information security assessments in the automotive industry on behalf of the VDA. The TISAX assessments are performed by audit providers who prove their qualification at regular intervals. TISAX and TISAX results are not intended for the general public.

Confidentiality, availability and integrity of information have a high priority for zrenner GmbH. We have taken extensive measures to protect confidential information. In doing so, we are guided by the questionnaire on information security of the German Association of the Automotive Industry (VDA ISA). The assessment was carried out by an audit provider, in this case the TISAX audit provider Operational Services GmbH & Co. KG. The result can be accessed exclusively via the ENX portal.
