US Patent 11245731 Protecting web applications from untrusted endpoints using remote browser isolation

Disclosed herein are techniques for protecting web applications from untrusted endpoints using remote browser isolation.

A surrogate browser is provided to facilitate communications between the client browser and the remote application. A security policy is enforced against the communications.
