What does Menlo Security do?
The Menlo Browser Security Platform is designed to secure web browsing activity for the modern enterprise, which now includes a mix of human users and AI agents. It functions by isolating browsing sessions, applying data loss prevention (DLP) policies, and preventing threats like malware and phishing. The platform uses a hybrid architecture that combines a local browser extension for low-risk activities with cloud-based isolation for high-risk browsing, ensuring that threats are neutralized before they reach the user or agent.
What makes Menlo Security stand out is its specific focus on securing AI agents, which are autonomous programs that perform tasks in a browser. It addresses unique risks like prompt injection attacks and unauthorized data exfiltration to external AI models. The platform provides a single control plane to manage security policies for both human and AI users, offering visibility and control over all browser sessions regardless of who—or what—is initiating them.
This tool is most beneficial for large enterprises in regulated industries like finance and healthcare that are beginning to deploy AI agents for automation. Use cases include securing customer service chatbots that interact with web applications, protecting internal AI workflows that scrape data from legacy systems without modern APIs, and ensuring that browser-based AI assistants in tools like Microsoft Copilot do not accidentally expose sensitive company information.
