TISAX (Trusted Information Security Assessment Exchange) is an information security assessment standard built for the automotive industry, based on the VDA Information Security Assessment (ISA) catalog.
Rather than every OEM running its own supplier security audit, a supplier completes one TISAX assessment through an approved provider and shares the results with multiple manufacturers via the ENX portal. Scope can extend beyond standard information security to prototype protection and data protection, reflecting how sensitive automotive design data is.
