Privacy Researcher Warns Edge Secure Network May Not Deliver True VPN Protection

Microsoft Edge Secure Network VPN is facing fresh scrutiny after a privacy researcher questioned whether the built-in feature works like a true VPN or more like a proxy service.

The criticism comes shortly after Microsoft faced pressure in Brazil over claims that it forces OEMs to preinstall Edge. Now, attention has shifted to how Edge promotes its privacy tools.

Edge Secure Network Under Privacy Spotlight

According to Windows Latest, Microsoft markets Edge Secure Network as a free, built-in privacy layer inside Microsoft Edge. The feature requires no extra apps or subscriptions and aims to protect users, especially on public Wi-Fi networks.

Users can enable it directly from the Secure Network section in browser settings. Microsoft describes the tool as using “VPN technology” to encrypt traffic generated within Edge and obscure the user’s IP address.

The service includes a free monthly data allowance of 5GB. Users must sign in with a personal Microsoft account to activate it, primarily to enforce that cap.

VPN or Just a Proxy?

According to a privacy researcher, Edge Secure Network behaves more like an HTTP CONNECT proxy built on Cloudflare’s Privacy Proxy platform rather than a traditional VPN.

Unlike full VPN services, the feature does not create a system-wide encrypted tunnel. It only protects traffic generated inside the Edge browser. Other apps, background services, and device-wide connections remain unaffected.

The tool may activate automatically in higher-risk scenarios, such as unsecured networks, depending on its optimized mode. However, it excludes certain high-bandwidth services like streaming platforms to conserve the 5GB monthly allowance.

Users cannot manually select server locations. The system connects automatically to a nearby server. The feature also remains unavailable on managed or enterprise devices and does not operate in some regions.

Trust Model and Anonymity Concerns

The architecture relies on a two-party trust model. Microsoft manages identity verification, while Cloudflare handles traffic routing.

Critics argue that requiring a Microsoft account removes a layer of anonymity. They warn that even if identities remain separated from browsing data, users must trust both companies’ assurances.

Microsoft states that Cloudflare does not see account identities. Cloudflare says it does not inspect user traffic. However, the researcher notes that the system depends on company claims rather than an independent public audit.

Not a Replacement for Full VPN Software

Microsoft positions Edge Secure Network as a baseline safeguard, not a full VPN replacement.

Browser-based protections prioritize convenience and basic encryption. They do not offer advanced features such as system-wide routing, kill switches, or configurable server locations.

The broader issue is not unique to Microsoft. Any browser-integrated VPN or proxy solution shares similar limitations. It encrypts browser traffic only and cannot replace a dedicated, system-wide VPN.

The controversy arises as Microsoft continues reshaping Edge. The company is removing the Collections feature and expanding Edge for Business capabilities.

Edge for Business will soon gain the ability to analyze Office files and even review open tabs, further embedding Microsoft’s productivity and AI tools directly into the browser experience.
