Admin-defined network access controls for Agent Platform remote flows

Administrators can now define centralized network policies for GitLab Duo Agent Platform remote flows directly in Settings. Top-level group administrators on GitLab.com, and instance administrators on GitLab Self-Managed and Dedicated, can configure organization-wide domain denylists and allowlists that projects inherit automatically. An additional setting controls whether projects can extend the approved domain list with custom entries. Policies are enforced at runtime across all remote flows, giving security and platform teams a consistent governance layer for agent network egress.
