EXTENSION SECURITY
Know what your browser extensions can access.
Browser extensions can access powerful browser capabilities, interact with web pages, and handle sensitive user data. PexLens analyzes extensions and their security signals to identify risky extensions before they become a problem.
Extension Intelligence
Understand permissions, publisher, reputation and extension context.
Risk Detection
Identify suspicious or potentially malicious extension indicators.
Policy Control
Allow, review or block extensions based on security requirements.
THE PROBLEM
Extensions are trusted too easily.
An extension may look harmless, but its permissions and behavior can give it access to sensitive browser activity.
High-risk permissions
Some extensions request access that can expose sensitive browser activity or data.
Unknown or untrusted publishers
Publisher identity, reputation and history can provide important security context.
Changes after installation
An extension that was acceptable yesterday can introduce new risk after an update.
