TISAX Details
What It Is
TISAX (Trusted Information Security Assessment Exchange) is an industry framework developed by ENX Association and VDA for automotive supply chain security. It standardizes assessments to protect sensitive data like prototypes and IP using VDA ISA catalog version 6.0 or later, with risk-based three assessment levels (AL1-AL3).
Key Components
- Seven control groups: Information Security Policies and Organization, Human Resources, Physical Security and Business Continuity, Identity and Access Management, IT Security / Cyber Security, Supplier Relationships, Compliance.
- 70+ controls extending ISO 27001 with automotive specifics like prototype protection.
- Modular objectives for information security, data protection, prototypes.
- ENX portal for label exchange; labels valid 3 years.
Why Organizations Use It
OEMs mandate TISAX contractually for suppliers, preventing contract loss and fines. It cuts duplicate audits (70-90% efficiency), boosts market access, mitigates breaches (€4.5M avg cost), builds trust in €2.5T chain.
Implementation Overview
Phased: Preparation (gap analysis), Remediation (controls, table-tops), Audit (AL2/3), Sustainment. Targets automotive ecosystem (OEMs, Tier 1/2, services); scalable for SMEs to globals via self-assess or on-site audits.
ISO 17025 Details
What It Is
ISO/IEC 17025:2017 is the international standard titled General requirements for the competence of testing and calibration laboratories.

- Covers personnel competence, facilities, equipment traceability, method validation, uncertainty evaluation, and reporting.
- Built on risk-based thinking, aligned with ISO 9001 (Option B integration).
- Accreditation model via ILAC-recognized bodies assessing technical scope.
Why Organizations Use It
- Enables market access, regulatory acceptance, and international result recognition.
- Mitigates risks from invalid results in safety-critical sectors.
- Builds stakeholder trust, competitive edge via credible accreditation.
Implementation Overview
- Phased PDCA: gap analysis, documentation, technical validation, audits.
- Applies to labs of all sizes in testing/calibration; requires witnessed assessments. (178 words)
