Menlo Security launches IRIS extension to control AI use in existing browsers

Browser security company Menlo Security has launched Menlo IRIS, a browser extension that brings its enterprise security controls to the browsers employees already use, SiliconANGLE reported. Menlo says installation takes hours and needs no extra hardware.

The extension gives security teams visibility into and control over generative AI use, data movement, files and third-party browser extensions. It audits every extension installed across a company, with an inventory and real-time risk profiles. Data-loss controls cover the clipboard, printing, uploads and downloads, and web filtering steers staff toward approved AI services and limits what data can be typed into them, instead of banning the tools outright.

Menlo cites Verizon's 2026 Data Breach Investigations Report, which found regular AI use on corporate devices tripled from 15% to 45% of employees in a year, with 67% of those using non-corporate accounts. "Even a small team can get essential security running quickly on the browsers employees already use," said CEO Bill Robbins.
