TISAX Details
What It Is
TISAX (Trusted Information Security Assessment Exchange) is an industry framework for standardizing information security assessments in the automotive supply chain. Developed by VDA and managed by ENX Association, it verifies protection of sensitive data like IP, prototypes, and personal information. It uses a risk-based approach with VDA ISA catalog, extending ISO 27001 for automotive needs across CIA triad plus prototype protection.
Key Components
- **7 control groupsPolicy, Organization, Personnel, Physical Security, Access, Cryptography, Operations.
- 70+ controls in VDA ISA, maturity levels 0-5 (min 3 required).
- Assessment levels: AL1 (self), AL2 (remote), AL3 (on-site).
- Modules for info security, data protection, prototypes; 3-year labels via ENX portal.
Why Organizations Use It
OEMs mandate it contractually for suppliers; non-compliance risks contract loss, fines. Provides audit efficiency (one assessment, many partners), market access, risk mitigation (breach prevention), trust in supply chain. Builds resilience, ROI via reduced duplicates (70-90% savings).
Implementation Overview
Phased: preparation/gap analysis (1-3m), remediation/tabletops (3-9m), audit/label (2-4m). Applies to OEMs, Tier 1/2 suppliers, services; scalable for SMEs/multinationals. Requires ENX-accredited auditors; self-assess for Basic, on-site for Very High.
ISO 20000 Details
What It Is
ISO/IEC 20000-1:2018 is the international certifiable standard for establishing and operating a service management system (SMS). It provides auditable requirements for managing the full service lifecycle—planning, design, transition, delivery, and improvement—using a risk-based, PDCA (Plan-Do-Check-Act) approach aligned with Annex SL for integration with other ISO standards.
Key Components
- **Clauses 4-10Context, leadership, planning, support, operation, performance evaluation, improvement.
- **Clause 8 operationsService portfolio, relationships, supply/demand, design/transition, resolution/fulfilment, assurance.
- Core processes: Incident/problem management, change/release, configuration/asset, availability/continuity, security.
- Certifiable via accredited bodies with Stage 1/2 audits, surveillance, recertification.
Why Organizations Use It
- Drives service reliability, customer trust, risk reduction (e.g., 50% certificate growth).
- Enables market differentiation, procurement wins, integration with ISO 9001/27001.
- Supports voluntary compliance for ITSM maturity across industries.
Implementation Overview
- Phased: Gap analysis, design, deploy, audit (12-18 months typical).
- Applies to all sizes/services; requires leadership, training, tooling, continual improvement.
