# Open-In Kasm Browser Extension

The Open-In Kasm Browser Extension provides a browser context-menu option for opening a link in an isolated Kasm Session.
Allowing a user that is navigating the web to easily open untrusted links with the malware protection and anonymization
that Kasm Isolation provides.
