AppGate provides Zero Trust Network Access (ZTNA) solutions and cyber advisory services to enterprises and government agencies. The company's ZTNA platform secures access to organizational resources by implementing zero trust security principles, enabling organizations to protect their assets while supporting remote and hybrid work environments.

AppGate's product portfolio centers on its ZTNA solution, which provides secure access controls based on identity verification, device posture, and contextual factors rather than traditional network perimeter defenses. The platform is designed to reduce operational costs, improve security efficiency, and minimize risk exposure through granular access policies and continuous authentication.

In addition to its technology offerings, AppGate operates a Cyber Advisory Services division that delivers cybersecurity consulting and compliance programs. This service draws on expertise from team members with backgrounds in federal law enforcement, including former FBI personnel, and provides advisory services for regulated industries.

The company serves both commercial enterprises across sectors like financial services, healthcare, and technology, as well as government customers including the U.S. Air Force, U.S. Marine Corps, and GSA. AppGate's leadership team includes executives with experience from organizations such as Microsoft, Palo Alto Networks, Cisco, and the FBI.

AppGate operates globally with a distributed team and maintains partnerships with managed security service providers and systems integrators to deliver and support its solutions across different markets and deployment scenarios.
