TISAX stands for Trusted Information Security Assessment Exchange. It is a standardized assessment and exchange mechanism for information security assessments in the automotive industry. TISAX provides a framework for assessing and managing information security risks in the automotive supply chain. TISAX and ISO have overlaps and can be implemented in an integrated way. TISAX gets labeled, wherever ISO is certificated. I some cases you need to provide evidences to fulfill both standards, which is better be done with an integrated method than split in two separate projects.
