TISAX Details
What It Is
TISAX (Trusted Information Security Assessment Exchange) is an industry-specific certification framework developed by the ENX Association and VDA for the automotive supply chain. It standardizes assessments of information security, focusing on protecting sensitive data like prototypes and IP. The risk-based approach uses VDA ISA catalog with three assessment levels (AL1-AL3) based on protection needs.
Key Components
- 70+ controls across policy, access, operations, and supplier relationships.
- Automotive modules for prototype protection (parts, vehicles, events).
- Builds on ISO 27001 with maturity grading (0-5 scale).
- ENX portal for exchanging results; labels valid 3 years.
Why Organizations Use It
- Contractual mandates from OEMs like BMW, Volkswagen.
- Mitigates supply chain risks, reduces duplicate audits (70-90% savings).
- Enables market access, boosts trust, and drives ROI via efficiency.
- Enhances resilience against cyber threats and IP theft.
Implementation Overview
Phased: preparation/gap analysis (1-3 months), remediation/tabletops (3-9 months), audit/certification (2-4 months). Scalable for SMEs to enterprises in automotive; requires accredited auditors for AL2/AL3.
ISO 50001 Details
What It Is
ISO 50001:2018 is an international standard specifying requirements for establishing, implementing, maintaining, and improving an Energy Management System (EnMS). It applies to organizations of any size or sector, focusing on systematic enhancement of energy performance—efficiency, use, and consumption—via the Plan-Do-Check-Act (PDCA) cycle and Annex SL High-Level Structure for integration with standards like ISO 9001 and 14001.
Key Components
- Core elements: energy policy, review, Significant Energy Uses (SEUs), Energy Performance Indicators (EnPIs), baselines (EnBs), objectives, action plans, monitoring, audits, and continual improvement.
- Built on PDCA; no fixed number of controls but mandates documented energy planning and measurement.
- Optional certification by accredited bodies per ISO 50003.
Why Organizations Use It
- Drives cost savings (4-20% energy reduction), regulatory compliance, GHG reductions, and resilience.
- Meets stakeholder demands, enhances ESG reputation, and supports procurement advantages.
Implementation Overview
- Phased approach: gap analysis, energy review, data collection, controls, audits, management review.
- Scalable across industries; certification involves Stage 1/2 audits. (178 words)
