Why Extension Auditor?
Get visibility and control over browser extensions across your organization. Identify risks, enforce policies, and protect your workforce.
Research-Backed
Analysis
Our risk models are built on 30+ peer-reviewed security papers covering extension threats, permission abuse, and supply chain attacks.
Not heuristics. Not guesswork. Real academic research translated into actionable risk scores.
Catch Changes Before Incidents
We monitor 11 event types every 2 hours—permission changes, ownership transfers, visibility shifts, and more.
Get alerted the moment an approved extension turns risky, not after it's already exfiltrated data.
Built for SMB and Enterprise Security Teams
Connect Google Workspace or Microsoft 365 in minutes. Alerts flow to Email, In-app Notifications, Slack, Teams, or your SIEM via webhook. Full REST API for automation.
848,448+ Extensions Analyzed
