Menlo IRIS extension gives security teams control over AI use without a new browser

Menlo Security Inc. launched the Menlo IRIS Browser Extension, a centrally managed extension that adds enterprise browser security controls to the browsers employees already use, with installation claimed to take only hours and no additional hardware required. The extension provides visibility into and control over generative AI use, data movement, files and third-party extensions, and deploys via the Chrome Web Store, Microsoft Intune, Jamf or other device management tools across Chrome, Edge, Safari, Firefox and Chromium-based AI browsers. Menlo cited Verizon Communications Inc.'s 2026 Data Breach Investigations Report, released in May, which found regular AI use on corporate devices tripled from 15% to 45% of employees in a single year, with 67% of people accessing AI services on corporate devices using noncorporate accounts and more than 15% of users at the average company running unauthorized AI browser extensions.

Exclusive: Menlo IRIS extension gives security teams control over AI use without a new browser Browser security company Menlo Security Inc. https://www.menlosecurity.com/ today launched the Menlo IRIS Browser Extension, a new offering that adds its enterprise browser security controls to the browsers employees already use with no need to switch them to separate secure ones. Delivered as a centrally managed extension, Menlo IRIS is said to give security teams visibility into and control over generative artificial intelligence use, data movement, files and third-party extensions. Installation is claimed to take only hours, as no additional hardware is needed. Chief Executive Bill Robbins, who took over the top job from co-founder Amir Ben-Efraim in February, said security teams have known for some time that the browser is a blind spot. Many have nonetheless held off on fixing it to avoid replacing an existing security stack, which typically means a big migration project, he added. “Menlo IRIS removes those obstacles,” Robbins said. “Even a small team can get essential security running quickly on the browsers employees already use.” To make its case, Menlo pointed to Verizon Communications Inc.’s 2026 Data Breach Investigations Report, released in May https://www.verizon.com/business/resources/reports/dbir/ , which found regular AI use on corporate devices tripled from 15% to 45% of employees in a single year. Some 67% of people accessing AI services on corporate devices were found to be using noncorporate accounts, with more than 15% of users at the average company also running unauthorized AI browser extensions. Among the headline capabilities is an audit of third-party browser extensions. Menlo says the audit covers every extension installed across a company, with an enterprise-wide inventory, real-time risk profiling and management controls all included. Few security teams have a count of the extensions their users have installed, according to Menlo. The company also warned that an extension’s risk profile can change at any time without notice. Data-loss controls cover the clipboard, printing, uploads and downloads, with watermarking, read-only pages, restrictions on developer tools and screenshot deterrence also included. Web filtering steers users toward sanctioned tools, including generative AI services, with limits on what data can be entered into them offered as an alternative to banning the tools outright. File security is part of the package as well, with inline inspection for data loss prevention violations, viruses and malware. For customers that want it, content disarm and reconstruction can be switched on to strip malicious content from files so they remain usable. Also available as an add-on is HEAT Shield AI for protection against zero-day phishing, social engineering and malvertising at the time of the click. Deployment is through the Chrome Web Store, Microsoft Intune, Jamf or other device management tools, with support for Chrome, Edge, Safari, Firefox and Chromium-based AI browsers. Since nobody has to switch browsers, security patches from each browser’s vendor are said to keep reaching users as normal. Most controls are enforced inside the browser session itself, which the company says removes the need for a proxy to route traffic. Menlo IRIS is intended to sit alongside existing network and endpoint tools. The Menlo IRIS Browser Extension is available now. Menlo Security has raised $250 million in funding, including a $100 million round in November 2020 https://siliconangle.com/2020/11/12/setting-course-ipo-menlo-security-picks-100m-funding/ .
