How a safe web gateway protects your browser
Understand what a controlled web gateway can protect, what it deliberately removes, and where its limits begin.
A web gateway sits between your browser and a public resource. Instead of handing the remote site your browser cookies and allowing every active script to run, Unblock Web requests the approved page on the server and returns a reduced, read-only preview.
What the gateway checks
Before any request is made, the destination must match the administrator-approved domain list. DNS results and every redirect are checked again to block localhost, private networks, link-local addresses, and unsupported protocols.
What reaches the browser
Scripts, forms, frames, embedded objects, refresh redirects, and event-handler attributes are removed from HTML previews. This reduces tracking and prevents the preview from behaving like the original interactive application.
A safe preview is useful for public information. It is not a replacement for logging in to an interactive website.
Where the boundary is
Unblock Web does not bypass passwords, subscriptions, organizational filters, or platform restrictions. Video platforms, authenticated applications, and complex JavaScript sites may not work because those features depend on the very capabilities a safe preview removes.
