Install Appgate SDP

Appgate Software-Defined Perimeter (SDP) is a DoD-approved authentication service that enforces Zero Trust principles for secure network access. Managed by the Platform One (P1) Cloud Native Access Point (CNAP) team, Appgate SDP helps protect DoD networks by:  

  • Denying implicit trust for users, devices, and applications  
  • Enforcing a “verify-then-trust” approach  
  • Granting least-privilege access based on verified credentials  

Appgate SDP is required to securely access Impact Level 4 (IL4) and Impact Level 5 (IL5) environments when connecting from a non-NIPRNet network — such as a commercial or public internet connection.

  • IL4 environments: Require Appgate SDP
  • IL5 environments: Require Appgate SDP and may also require running compliance scripts

Why Appgate SDP matters for Game Warden access 

Game Warden relies on P1 CNAP and Appgate SDP to enforce access controls for IL4 and IL5 environments.

  • Appgate, combined with DoD-approved security measures, ensures compliance with the Cloud Computing Security Requirements Guide (SRG) — particularly sections 5.10.1.x of SRG v1, Release 4.
  • Without Appgate SDP (or a direct NIPRNet connection), you cannot reach Game Warden-hosted IL4+ environments.
