Microsoft’s Edge browser has been promoting its "Secure Network" feature as a built-in VPN solution aimed at enhancing user privacy and security. However, cybersecurity experts are raising concerns, arguing that the feature does not function as a true VPN and may not offer the level of protection users expect.
Key Takeaways
- Microsoft Edge’s "Secure Network" is described by experts as an HTTP CONNECT proxy, not a full VPN.
- The feature only tunnels traffic within the Edge browser, leaving other applications and system traffic exposed.
- Users are required to log in with a Microsoft account, raising potential privacy concerns.
- While Microsoft claims its partner Cloudflare cannot access user identities, the limited scope of protection is a significant drawback.
Not a True VPN, Experts Say
Privacy researcher Sooraj Sathyanarayanan, who works at Brave Software, has debunked Microsoft’s marketing of the Edge Secure Network. Sathyanarayanan explains that the feature is essentially an HTTP CONNECT proxy built on Cloudflare’s Privacy Proxy Platform. Crucially, it only encrypts and routes traffic originating from within the Edge browser itself. This means that all other applications on a user’s system, including email clients, background services, operating system updates, and even DNS queries, remain unprotected and exposed.
Privacy Concerns and Limitations
To utilize the Edge Secure Network, users must be logged into their Microsoft accounts. This requirement has led to concerns about personal privacy, as the protection layer is tied to an authenticated identity rather than anonymous usage. Microsoft states that Cloudflare, the partner handling the traffic, does not have access to user identities and will not inspect the traffic. However, the system relies on trusting both Microsoft and Cloudflare’s claims without independent public audits.
Furthermore, the feature has several limitations. It offers a capped 5GB of data per month, after which the protection ceases until the quota resets. High-bandwidth activities like video streaming are excluded to conserve data. The feature is also not available on managed or enterprise devices and does not support manual server selection, automatically connecting to a nearby server instead.
Browser-Integrated Protection vs. Full VPN
While Microsoft positions the Edge Secure Network as a convenient, built-in safeguard, experts emphasize that it is not a substitute for a traditional VPN service. Unlike full VPNs that route all system traffic through an encrypted tunnel and offer features like kill switches and user-configurable server locations, the Edge feature’s scope is limited to the browser. This distinction is important for users to understand to set realistic expectations about the level of privacy and security they are receiving.
