TISAX vs CAA
TISAX
Automotive standard for secure information assessment exchange
CAA
U.S. federal statute regulating air emissions and quality standards
Quick Verdict
TISAX ensures information security for automotive supply chains via assessments, while CAA mandates emission controls for all industries through permits and monitoring. Automotive firms adopt TISAX for OEM contracts; manufacturers use CAA to avoid fines and ensure operations.
TISAX
Trusted Information Security Assessment Exchange (TISAX)
Key Features
- Secure exchange of assessments via ENX portal
- Automotive-specific prototype protection controls
- Three risk-based assessment levels AL1-AL3
- VDA ISA catalog with 70+ tailored controls
- Three-year reusable labels reduce duplicate audits
CAA
Clean Air Act (CAA), 42 U.S.C. §7401 et seq.
Key Features
- National Ambient Air Quality Standards (NAAQS) for criteria pollutants
- State Implementation Plans (SIPs) and Federal oversight
- Technology-based NSPS and MACT emission standards
- Title V operating permits consolidating requirements
- Multi-vector enforcement including penalties and sanctions

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 federalism. EPA 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.
