TISAX Overview
TISAX (Trusted Information Security Assessment Exchange) is a European assessment and exchange framework for information security in the automotive industry.
Managed by the ENX Association, TISAX standardizes how automotive manufacturers, suppliers, and service providers demonstrate and share security assessments.
Purpose of TISAX
TISAX aims to harmonize information security assessments across the automotive supply chain.
It ensures that participants meet common security requirements and can share assessment results through a trusted exchange platform, eliminating redundant audits.
Scope and Applicability
TISAX applies to organizations that process or handle sensitive information for automotive manufacturers, suppliers, or partners.
Assessment levels vary depending on data sensitivity and business context:
Level 1: Self-assessment.
Level 2: External audit for standard confidentiality.
Level 3: On-site audit for highly confidential or prototype-related information.
What the Framework Covers
TISAX requirements are based on ISO 27001 and the VDA-ISA (Information Security Assessment) catalog.
Key domains include:
Information security management.
Prototype and product protection.
Third-party management and physical security.
Data protection aligned with GDPR.
Certification and Assessment
Assessments are conducted by TISAX-approved audit providers.
Results are uploaded to the TISAX exchange platform, where participants can share verified status with partners. Certification validity typically lasts three years.
Implementation and Continuous Compliance
Organizations should establish an ISMS aligned with ISO 27001 and VDA-ISA requirements, perform internal audits, and maintain continuous improvement cycles.
Assessment scope and level should be determined based on customer requirements and the sensitivity of the handled data.
