While browser extensions can greatly boost productivity, they also introduce significant security risks, especially in enterprise environments where consumer browsers and third-party add-ons access sensitive data. Why?

  • Extensions run code with elevated privileges and often request broad permissions. 
  • Malicious and vulnerable extensions can enable data theft, credential compromise, and malware delivery. 
  • Poor user awareness and lack of centralized visibility into installed extensions exacerbate these risks. 

The guide emphasizes the need for comprehensive governance—including inventory, permission assessment, and risk controls—to mitigate extension-related threats and protect organizational assets from exploitation.
