Appgate SDP provides secure, direct connectivity between users and protected resources using Zero Trust Network Access (ZTNA) and Software-Defined Perimeter architecture. Operating at the network layer, it enables real-time responses to environmental changes and dynamic access control based on user attributes. The solution integrates with existing security infrastructure, including identity management and SIEM systems, while supporting hybrid cloud environments through a distributed deployment model. Features include Single Packet Authorization to cloak infrastructure, microfirewalls for least privilege access, and mTLS encryption for secure connections. The platform is cloud-native, API-enabled, and offers high availability and scalability for enterprise deployments.
