AI Compliance: EU AI Act, NIST AI RMF, and Enterprise LLM Requirements (2026)
AI compliance is system design, not paperwork. The EU AI Act and NIST AI RMF both require continuous testing, documentation, and monitoring. This guide covers what compliance demands technically and how AIZA provides the LLM security testing and audit evidence components.
What is AI compliance?
AI compliance ensures AI systems meet legal, regulatory, and industry standards for safety, transparency, security, and accountability — through continuous testing, documentation, and monitoring rather than periodic audits.
- EU AI Act: risk classification, technical documentation, post-market monitoring
- NIST AI RMF: Govern, Map, Measure (AIZA), and Manage functions
- Continuous monitoring required — not one-time certification
- Non-compliance: EU fines, market restrictions, lost enterprise contracts
EU AI Act — risk tier requirements
| Risk tier | Examples | Requirements |
|---|---|---|
| Unacceptable | Social scoring, manipulative AI | Banned entirely |
| High risk | Healthcare AI, financial AI, employment screening | Risk assessment, technical docs, continuous monitoring |
| Limited risk | Customer service chatbots | Transparency disclosures |
| Minimal risk | Spam filters, basic tools | Light oversight |
NIST AI RMF — where AIZA fits
Govern
AIZA's Authorization Attestation ID system enforces governance at the scan level — every scan links to documented authorization, creating an accountable audit trail.
Map
AIZA's 23-phase scan covers the AI attack surface systematically — input, retrieval, model, and output layers — mapping your specific threat landscape.
Measure ← AIZA's primary contribution
Systematic security evaluation across 23 vulnerability phases. Findings exported in STIX 2.1 and MITRE ATT&CK formats as technical evidence artifacts for compliance documentation.
Manage
AIZA's remediation guidance maps each finding to specific technical controls. API integration enables continuous scanning across model and deployment changes.
AI compliance checklist
