WEBINAR

Browser extensions are widely used productivity tools in most enterprises. But as numerous recent breaches have shown, they're also one of security's biggest blind spots: errant extension use leaves enterprises open to malicious extensions, unauthorized data theft, and code injections that slip past security controls.

In this webinar, SquareX Field CISO John Carse will show you how to build effective extension governance without killing productivity, focusing on practical approaches — specifically, how browser-native security can finally give you the visibility and control that endpoint and network tools miss.

This 45-Minute session covers:

🧩 The current state of browser extension threats

 🔎 Implementing granular controls through Browser Detection and Response (BDR)

🛡️ Building an extension security program that balances productivity and risk management
