Menlo Security unveiled its IRIS Browser Extension, designed to give security teams centralized control and visibility over AI use, data movement, and third-party extensions within the browsers employees already use, eliminating the need for switching to secure, standalone browsers.
- Adds AI and browser security controls to existing browsers via managed extension
- Audits third-party extensions and enforces data loss prevention in real time
- Deploys quickly without hardware changes or switching browsers
What happened
Menlo Security launched the IRIS Browser Extension that delivers enterprise-grade security controls directly within popular internet browsers used by employees, such as Chrome, Edge, Safari, and Firefox. This approach avoids the traditional need to switch users to a separate secure browser, simplifying adoption and reducing migration delays.
Menlo IRIS provides security teams visibility and control over generative AI use, data movements like clipboard and file uploads/downloads, and third-party browser extensions. The extension enables monitoring, real-time risk profiling, and management of all installed extensions at the enterprise level while enforcing data security measures such as watermarking and screenshot deterrents.
Why it matters
Recent research, including Verizon’s 2026 Data Breach Investigations Report, revealed a sharp increase in AI use on corporate devices, with many employees accessing AI tools through unauthorized accounts and extensions. Such unchecked activity creates significant blind spots in corporate cybersecurity postures.
Menlo IRIS addresses these risks by empowering even small security teams to implement critical protections quickly, without disrupting user workflows or installing new hardware. The extension’s in-browser enforcement and compatibility with device management tools reduce operational complexity and complement existing network and endpoint security investments.
What to watch next
Adoption rates of browser-centric security solutions like Menlo IRIS will be a key indicator of enterprise readiness to manage AI risks, especially as generative AI tools become increasingly integrated into daily workflows. Organizations will likely monitor how effectively such extensions mitigate exposure without impeding productivity.
Another critical area will be evolving capabilities in third-party extension auditing and dynamic risk profiling, given that extensions can change their behavior or risk status unexpectedly. Expansion of Menlo IRIS’s features, including the HEAT Shield AI add-on for phishing and malware protection, will be important to watch as companies refine their browser security strategies.
