TISAX Details
What It Is
Trusted Information Security Assessment Exchange (TISAX) is an industry-specific certification framework developed by the ENX Association and VDA for the automotive sector. It standardizes assessments of information security, focusing on protecting sensitive data like prototypes and IP in global supply chains. Rooted in ISO 27001, it uses a risk-based approach with VDA ISA catalog controls and three maturity-based assessment levels (AL1-AL3).
Key Components
- **Seven control groupsPolicy, Organization, Personnel, Physical Security, Access, Cryptography, Operations.
- Over 70 controls with 0-5 maturity grading.
- Modules for prototype protection, data protection, and availability.
- Three-year labels issued via ENX portal after audits.
Why Organizations Use It
OEMs mandate TISAX contractually for suppliers, enabling market access and revenue. It mitigates risks like IP theft, reduces duplicate audits by 70-90%, builds trust, and provides competitive edges in €2.5T automotive chain. Enhances resilience against cyber threats and GDPR scrutiny.
Implementation Overview
Phased: preparation/gap analysis (1-3 months), remediation/tabletops (3-9 months), audit/certification (2-4 months), ongoing sustainment. Applies to suppliers, OEMs, service providers; scalable for SMEs to enterprises via self-assessments or on-site audits by accredited providers like DQS/TÜV.
ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is the international standard providing requirements and guidance for establishing, implementing, maintaining, and improving a Privacy Information Management System (PIMS). It extends ISO 27001 with a privacy layer, focusing on managing PII risks for controllers and processors using a risk-based, PDCA management system approach.
Key Components
- Clauses 4–10 mirroring ISO 27001 with privacy extensions.
- Annex A (controller controls) and Annex B (processor controls) with ~50 privacy-specific objectives.
- Mappings to GDPR (Annex D), ISO 29100, and others.
- Certification via accredited bodies, three-year cycle with surveillance audits.
Why Organizations Use It
- Demonstrates accountability for GDPR/POPIA/LGPD compliance.
- Reduces privacy risks, enhances trust, aids procurement.
- Integrates with ISMS for efficiency.
Implementation Overview
- Phased: scope, gap analysis, controls, audits.
- 6-12 months typical; suits all sizes/industries processing PII.
- Requires RoPA, DSAR processes, risk assessments, internal audits.
Key Differences
| Aspect | TISAX | ISO 27701 |
|---|---|---|
| Scope | Automotive info sec, prototypes, CIA triad | Privacy management system for PII controllers/processors |
| Industry | Automotive supply chain, global but Europe-focused | All sectors handling PII worldwide |
| Nature | Voluntary industry assessment and exchange platform | Voluntary PIMS certification standard |
| Testing | AL1 self, AL2 remote, AL3 on-site audits, 3-year validity | Stage 1/2 audits, annual surveillance, 3-year certification |
| Penalties | Contract loss, no TISAX label, OEM exclusion | No legal penalties, loss of certification |
