Server-Initiated Connectivity

Deliver secure, controlled access for server-initiated connections.

Secure Service-to-User Connections

Certain protocols and services (such as VoIP, RDP, or SSH) require initiating sessions to end-user devices. Traditionally, enabling this exposes devices on the network, increasing the risk of unauthorized access or malicious traffic. AppGate ZTNA enforces a “service-to-client” model, treating endpoints like enterprise resources: invisible by default and only accessible to explicitly authorized services. Servers or services cannot initiate connections unless policies allow it, ensuring that only trusted, authenticated communications reach user devices—without opening inbound network ports.

  • Invisible Endpoints: User devices are cloaked from all unauthorized services by default, eliminating unnecessary exposure.
  • Policy-Driven Server Access: Servers and services can only initiate traffic to devices when explicitly entitled, controlling service-to-user flows.
  • Service-Centric View: Entitlements define exactly which devices are reachable from each service, preventing lateral movement and broad network visibility.
  • Highly Performant: AppGate’s point-to-point connectivity ensures efficient delivery of server-initiated traffic without routing through unnecessary middle points.

How It Works

AppGate ZTNA ensures that server-initiated connections reach only verified users who are explicitly authorized with the appropriate entitlements.

Service Authentication

Service accounts are authenticated through secure identity providers, supporting multiple providers for flexibility.

Dynamic Policy Enforcement

Access policies are enforced in real-time, ensuring user devices are only accessible to server-initiated connections under the right conditions.

Risk-Based Access Evaluation

The system evaluates the risk associated with each user request, considering device posture, location and other contextual factors.

Continuous Monitoring

Sessions are continuously monitored, and access controls adapt to emerging risks. 

Implementation Steps

Deliver services to users securely, with minimal setup by defining entitlements, configuring service policies, and monitoring access in real-time.

1 Configure Identity Providers

Integrate your preferred identity providers into AppGate ZTNA to manage user authentication. 

2 Define Risk Rules and Access Policies

Create and customize risk rules and access policies aligned with organizational security requirements.

3 Set Up User Interactions

Configure user interactions for scenarios requiring additional verification, such as multi-factor authentication (MFA). 

4 Deploy and Configure Service Clients

Ensure service clients are properly configured to communicate with AppGate ZTNA.

5 Monitor and Adjust

Use monitoring tools to track user interactions and adjust policies to maintain security and compliance. 

Benefits and Outcomes

AppGate ZTNA enforces least-privilege for server-initiated connections: endpoints remain cloaked, and only entitled services can initiate traffic.

  • Only authorized servers or services can connect to designated user devices.
  • User devices remain hidden from scans, probes, and lateral movement.
  • Direct connections improve performance for VoIP, RDP, and SSH sessions.
  • Detailed logs provide visibility into which services connected to which devices.
