Sophos AI Defense finds the AI tools employees and applications are using, including the ones security teams never approved, and enforces policy wherever they run. Every AI tool an organization can’t see is a potential gap in confidentiality, integrity, and availability. Delivered through Sophos Fusion, the AI-native cybersecurity defense system, Sophos AI Defense connects controls on the device, across the network, at sign-in, and in the browser into one line of defense, so teams can safely adopt AI faster without adding another disconnected tool to manage.
