AI Security: Matt Sharp on Shadow AI, NHIs, and AI Defense
What does AI security actually look like inside real organizations?
In this episode of ClearTech Loop, Jo Peterson talks with Matt Sharp, Chief Information Security Officer at Xactly, about shadow AI, non human identities, and what leaders should really mean when they talk about AI defense. They unpack why shadow AI is both an IT and security issue, how CISOs and CIOs are approaching identity and governance, and why AI defense now spans productivity tools, SaaS platforms, internal environments, and third party risk.
In this episode of ClearTech Loop, Jo Peterson sits down with Matt Sharp for a grounded conversation on three issues reshaping enterprise AI governance: shadow AI, NHIs, and AI defense. Matt brings a practical view from inside a real operating environment, where AI adoption is moving fast and governance, identity, and risk have to keep up. In the conversation, he explains why shadow AI is not just a security problem. It is also an IT, tooling, and governance problem, especially when organizations are trying to steer employees toward approved AI tools while protecting enterprise data.
The conversation then shifts to non human identities, where Matt argues that AI agents are being layered into authorization models that organizations never fully solved in the first place. From there, Jo and Matt dig into AI defense as a broader enterprise challenge that now touches browser extensions, IDEs, local models, SaaS platforms, and third party risk. This episode is especially relevant for CIOs, CISOs, security leaders, IT leaders, and enterprise technology teams trying to balance AI adoption with governance, visibility, and accountability.
