Zero Trust as Foundational Infrastructure for Enterprise AI Enablement presents Zero Trust as an operational force multiplier in the AI era. Grounded in enterprise security architecture, it reframes security from risk containment to strategic acceleration. Drawing from CISA’s Zero Trust Maturity Model, NIST SP 800-207, the CSA AI Controls Matrix, and SABSA’s design principles, it argues that foundational Zero Trust maturity offers a stable and practical substrate for responsible AI adoption. By operationalizing Zero Trust as both a control system and a capability accelerator, enterprises can achieve safe velocity. They gain the ability to innovate confidently, integrate AI broadly, and convert governance into sustainable growth.
