What It Is
TISAX (Trusted Information Security Assessment Exchange) is an industry-specific assessment framework for information security in the automotive supply chain. Developed by the ENX Association based on the VDA ISA catalog version 6.0, it verifies protection of sensitive data like prototypes and IP using risk-based assessments at three levels: Basic (AL1), Significant (AL2), and Very High (AL3).
Key Components
- Controls aligned with ISO/IEC 27001:2022 themes: Organizational, People, Physical, and Technological.
- Automotive extensions for prototype protection, high availability, and data protection.
- Built on ISO/IEC 27001:2022 with maturity scoring (0-3+).
- ENX portal for registration, audits, and result exchange; labels valid 3 years.
Why Organizations Use It
