Browser extensions are now the leading attack vector in enterprise environments, driving the urgent need for proactive management and risk mitigation tools. With high-profile supply chain attacks compromising millions of users and the majority of data breaches now involving risky extensions, strong controls are essential.
Recent events, such as the December 2024 Cyberhaven incident, show how attackers use compromised extensions to steal credentials and sensitive information at scale—all within legitimate browser environments. Traditional security tools can miss these risks, highlighting the value of specialized extension monitoring.
Also, “shadow” extension deployment is rampant, with many users running unauthorized or sideloaded extensions. Over a quarter of enterprise extensions are installed outside official channels. Security teams must therefore assess both pre-deployment risk and post-deployment changes to defend against these threats.
Browsium now includes the Extension Analyzer, a tool designed to empower IT security teams to evaluate browser extensions before deployment. By uploading browser extension packages (.crx, .xpi, .zip), organizations receive instant, comprehensive risk score analyses.
Key Features:
Automated assessment for immediate risk intelligence
Configurable risk parameters tailored to organizational policies
Organizations can adjust scoring weights for various factors to align with their specific security requirements, improving the cadence and depth of extension reviews.
While the initial analysis helps understand the risks prior to extension deployment, Browser Extension updates can open a security hole where undesired permissions or activities are enabled after rollout. Browsium guards against that with the Extension Updates feature, which brings real-time visibility into every browser extension update across enterprise devices. This page provides:
Complete change visibility for any PC with Browsium Client
Side-by-side comparison dialogs for extension versions
Alerts for high-risk changes
This feature closes a critical security gap: while over half of enterprise extensions haven’t been updated in a year, updates that do happen can introduce vulnerabilities or malicious functionalities..
