Web security’s next frontier

For modern enterprises, the internet is the new corporate network, dramatically expanding the attack surface. Simultaneously, the escalation of zero-day vulnerabilities, ransomware, drive-by downloads, and other sophisticated attacks increases the risk of infection and data theft from web-based threats.

Cloud Browser Isolation reimagines web security by stripping attackers of their most advanced tools and techniques by safely isolating users and endpoints from all active web content. Cloud Browser Isolation helps you make web-based attacks—both past and future—obsolete.

“Many enterprises are now seeking more than just a proxy service in the cloud, as they add...remote browser isolation (RBI)...and other cloud-based security services.”

–Gartner, 2020 SWG MQ

A fundamentally different approach to security, built around zero trust with Cloud Browser Isolation, creates a safe gap between users and the web, rendering content as a benign stream of picture-perfect images to eliminate the delivery of active threats.
