Menlo Security Inc. has launched the Menlo IRIS Browser Extension, designed to provide enterprise-level security controls for existing web browsers. The solution allows security teams to monitor and manage the use of generative AI, data movement, and third-party extensions without requiring employees to switch to a new browser.
The extension can be deployed via the Chrome Web Store, Microsoft Intune, Jamf, or other management tools, supporting Chrome, Edge, Safari, Firefox, and Chromium-based browsers. Menlo Security reports that installation takes only hours and requires no additional hardware, as controls are enforced within the browser session.
Key features include real-time risk profiling for third-party extensions, data-loss prevention for clipboard and file operations, and web filtering to guide users toward sanctioned AI tools. The system also offers optional file sanitization and protection against phishing and social engineering via the HEAT Shield AI add-on.
The company cited a 2026 report from Verizon, which noted that AI usage on corporate devices grew from 15% to 45% in one year, with 67% of users accessing these services through non-corporate accounts. Additionally, over 15% of users at an average company utilize unauthorized AI browser extensions.
Menlo Security has raised a total of $250 million in funding. Its investor base includes Vista Equity Partners, JPMorgan Chase, American Express Ventures, and General Catalyst. The company is currently led by CEO Bill Robbins, who assumed the role in February.
