Identity-Centric Network Security: Entra Global Secure Access Architecture & Benefits

Is the traditional VPN dead? In the latest episode of Entra Chat, we dive deep Microsoft Entra Global Secure Access (GSA).Joined by Karen Simmel from the GSA product team and Thomas from the Entra CXE Architecture team, we explore how Microsoft is bridging the gap between identity and network security.The Shift from VPN to SASEThe "good old days" of spinning up firewalls and DMZs are fading. Traditional controls are often too coarse-grained and lack identity awareness. As Thomas explains, the COVID-19 pandemic accelerated the need for change when traditional VPN gateways physically couldn't handle the load of remote workforces.This has paved the way for SASE (Secure Access Service Edge) and SSE (Security Service Edge), which move security controls to the cloud at hyperscale.What is Global Secure Access?The team breaks down the confusing terminology to help you understand the core products:* Microsoft Entra Private Access: This is the ZTNA (Zero Trust Network Access) solution, replacing the classic VPN for accessing on-prem and private resources.* Microsoft Entra Internet Access: This acts as a Secure Web Gateway (SWG), protecting outbound access to SaaS apps and the internet with URL filtering and DLP controls.* Microsoft Entra Suite: A bundle that combines these network capabilities with Verified ID, Identity Governance, and Identity Protection for a comprehensive solution.The "Secret Sauce"Why choose Microsoft's solution? The differentiator is that GSA isn't just integrated with the Identity Provider (IdP)—it *is* part of the IdP.This deep integration allows for near real-time security. For example, if a user's device is compromised, the SOC team can revoke the token, and Entra can immediately terminate the network tunnel or prompt for step-up authentication. It brings the power of Conditional Access directly to network traffic.Better Performance, Better PrivacyContrary to the belief that security slows things down, GSA often improves performance. By leveraging Microsoft's massive global private fiber network, traffic is intelligently routed to the closest point of presence rather than being backhauled to a headquarters.From a privacy standpoint, admins have granular control. You decide what traffic is tunneled and inspected, ensuring you can meet compliance requirements (like those in the EU) without over-monitoring employee activity.Ready to Deploy?Deployment doesn't have to take months. Some customers are getting up and running with a Proof of Concept (PoC) in a single day. Whether you use the client-based agent or need client-less access for contractors, Microsoft provides detailed deployment plans to guide you.Subscribe with your favorite podcast player or watch on YouTube 👇About the GuestsKeren SemelKeren leads visibility and data insights for the Global Secure Access product group.
