Appgate

Appgate is a cybersecurity vendor focused on secure access technologies for enterprise and government environments, with a core emphasis on software-defined perimeter and zero trust network access controls.

• Zero trust network access (ZTNA) platform for secure, identity-centric access to applications and resources
• Software-defined perimeter (SDP) capabilities that segment networks and hide infrastructure from unauthorized users
• Access control policies that integrate user identity, device posture, and contextual attributes
• Solutions designed for hybrid IT, multicloud, and distributed workforces
• Security services and expertise that support deployment, integration, and ongoing operation of its secure access platform

More About Appgate

Appgate focuses on secure access for enterprise and public sector organizations through zero trust network access (ZTNA) and software-defined perimeter (SDP) technologies (network security). Its core platform is designed to replace or augment traditional remote access tools, such as VPNs, by enforcing access based on identity, device posture, and context rather than static network locations.

In typical enterprise deployments, Appgate’s platform sits between users and applications across data centers, private clouds, and public cloud providers. It authenticates users, validates device posture, evaluates contextual information such as time, location, and risk signals, then dynamically provisions encrypted connections only to authorized applications. Network-level access is restricted, and unauthorized infrastructure is not visible to end users, which reduces exposure to lateral movement and network reconnaissance.

The platform applies principles generally associated with zero trust architectures, including least-privilege access, continuous verification, and microsegmentation. Policies are defined centrally and enforced at the connection level, which allows security teams to express access rules based on attributes such as user role, group membership, device security status, and environment. This approach aligns with enterprise security frameworks that prioritize identity-aware controls and application-centric connectivity rather than broad network access.

From a technology perspective, Appgate’s offerings rely on encrypted tunnels, mutual authentication, and policy engines that integrate with identity providers, directory services, and security tooling already in use within large organizations (access management, identity, and Security Operations (SecOps)). The system commonly works alongside Single Sign-On (SSO) providers, Multifactor Authentication (MFA), Security Information and Event Management (SIEM) platforms, and endpoint security tools, allowing customers to reuse existing identity and security investments.

Appgate positions its secure access platform within the broader categories of network security, remote access, and zero trust access control. Enterprises use it to support distributed workforces, contractor access, third-party connectivity, and secure administration of critical systems across hybrid IT environments. Public sector and regulated industries adopt the platform to align with zero trust and software-defined perimeter guidance from government and industry standards bodies, while maintaining granular control over who can access specific applications and services.

Within a directory or marketplace context, Appgate fits primarily into zero trust network access (ZTNA), software-defined perimeter (SDP), secure remote access, and identity-aware network security categories, with secondary association to access management and security orchestration through its integrations and policy-driven controls.
