Modern network access has evolved, and Microsoft Entra Global Secure Access (GSA) is leading the transformation. Whether users are accessing private resources, Microsoft 365 services, or the internet, every request is now routed through an identity aware, Zero Trust-aligned infrastructure. This shift introduces new troubleshooting paradigms and this guide is here to help.
Why Global Secure Access Exists
Global Secure Access combines multiple security layers to deliver robust protection and optimized routing:
- Zero Trust enforcement for all traffic
- Unified identity, device, and network controls
- VPN replacement for private apps
- Secure outbound internet access
- Optimized Microsoft 365 routing
Traffic Profiles Explained
GSA categorizes traffic into three distinct profiles:
- Internet Access → Secure outbound browsing

- Microsoft 365 Access → Optimized, identity-aware routing

- Private Access → Zero Trust access to internal apps
