What is an enterprise browser?

Dedicated enterprise browsers give the deepest per-tab control but require every user to switch browsers — a real adoption and support cost, and coverage ends where installation ends. Browser extensions retrofit policy into existing browsers cheaply, but sit inside the thing they police and can be disabled or bypassed. Cloud isolation moves the session itself into a governed remote container: users keep their browser, coverage follows policy rather than installation, and threats execute away from the device.

The deciding questions: can you force a browser migration across the workforce, and does protection need to hold on unmanaged devices and for AI agents? Isolation-based approaches answer both without touching the endpoint, which is why Menlo Security frames the browser-security decision around session governance rather than browser replacement — the same model covering human users and autonomous agents.
