The MITRE ATLAS™ matrix catalogs 14 adversarial tactics and 84+ techniques used to attack AI systems. This assessment maps every tactic against Confidential AI architecture to answer the question blocking enterprise AI deployments: which threats actually matter, and what structurally eliminates them?

The finding is clear: 8 of 14 ATLAS tactics produce data exposure — the category that triggers CISO objections and regulatory scrutiny under DORA, EU AI Act, and GDPR. Confidential AI provides hardware-enforced structural defense against all 8. Four tactics receive partial coverage. Two, adversarial robustness and availability, fall outside scope and require complementary tooling. We say so plainly.

Grounded in MITRE ATLAS v4.1 (October 2025). An honest accounting of what confidential AI solves, mitigates, and doesn't.
