Ultrasurf review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Ultrasurf is a free VPN and proxy service from UltraReach Internet Corp. Its purpose is to help people access websites blocked by network censorship while browsing with greater privacy. It encrypts traffic between the client and its network and masks the user's IP address. Windows, Android and iOS clients, along with a browser extension for supported browsers, give individuals and small teams several ways to connect. Its clearest fit is someone looking for free access to blocked sites, rather than a buyer evaluating a broad VPN service for varied network needs.

The product's defining feature is its anti-censorship use: the service is presented as a way to reach websites blocked by network restrictions. Encryption and IP masking support the privacy side of that purpose, but the published product description centers on access and browsing rather than a wider set of VPN use cases. That focus makes Ultrasurf easier to assess for users with a specific access problem. It is less suitable for buyers who need a service selected around a broader feature checklist, since those needs do not form part of the stated product pitch.

Ultrasurf is positioned as free, with downloadable options for Windows, Android and iOS and an extension for supported browsers. That gives users a choice between standalone clients and a browser-based route, although extension use may not suit someone who wants a desktop-only workflow. Choose Ultrasurf if free, censorship-focused access and IP masking match the need. Look elsewhere if the decision depends on capabilities beyond those stated purposes, or on a particular platform outside the named clients and browser-extension option.
