Menlo Security

Browser security company isolating web sessions to keep threats off endpoints for users and AI agents.

Menlo Security executes web content in a cloud isolation layer so malware and phishing pages never run on the user's device. The platform manages and protects browsing for employees and, increasingly, for AI agents that operate inside browsers. Founded in 2012, it is used by enterprises and government agencies with strict security requirements.
