TISAX Details
What It Is
TISAX (Trusted Information Security Assessment Exchange) is an industry framework for standardizing and exchanging information security assessments in the automotive supply chain. Developed by ENX Association based on VDA ISA catalog, it verifies protection of sensitive data like IP and prototypes using a risk-based approach with three assessment levels: AL1 (self), AL2 (remote), AL3 (on-site).
Key Components
- VDA ISA controls (70+ across policy, access, operations, suppliers, prototypes)
- Modular objectives: information security, prototype protection (parts/vehicles/events), data protection
- Maturity scoring (0-5, min level 3)
- ENX portal for label exchange; 3-year validity
Why Organizations Use It
OEMs mandate TISAX contractually for suppliers, mitigating supply chain risks, enabling market access, reducing duplicate audits (70-90% savings). Builds trust, prevents breaches (€4.5M avg cost), aligns with ISO 27001.
Implementation Overview
Phased: scope/gap analysis (1-3 months), remediate/controls/tabletops (3-9 months), audit/label (2-4 months), sustainment. Scalable for SMEs to enterprises; ENX-accredited audits required. Targets automotive ecosystem globally.
CAA Details
What It Is
The Clean Air Act (CAA), codified at 42 U.S.C. §7401 et seq., is a comprehensive U.S. federal statute establishing the national framework for air pollution control. Its primary purpose is protecting public health and welfare from stationary and mobile source emissions through **cooperative federalismEPA sets standards, states implement via enforceable plans.
Key Components
- NAAQS for six criteria pollutants (ozone, PM, CO, Pb, SO2, NO2) with primary/secondary standards.
- SIPs/FIPs, NSPS, NESHAPs/MACT, Title V permits, NSR/PSD.
- Built on ambient outcomes, technology-based controls, permitting/enforcement.
- Compliance via monitoring, reporting; no central certification but state/Federal oversight.
Why Organizations Use It
Mandatory compliance avoids penalties, sanctions, citizen suits. Manages risks from nonattainment, enforcement. Enables permitting for expansions, supports ESG via emission reductions, builds stakeholder trust.
Implementation Overview
Phased: gap analysis (0-3 mo), strategy/design (1-6 mo), permitting/EPC (6-24 mo), ongoing monitoring/reporting. Applies to emitters nationwide; industries like manufacturing, energy. Requires audits, CEMS, SIP tracking.
