Browser Extensions Control

Eliminate the Hidden Risk in Your Browsers

Browser extensions are one of the most overlooked security blind spots. A seemingly harmless extension can exfiltrate sensitive data, capture keystrokes, inject ads, or compromise credentials. With employees using browsers for everything from email to cloud applications to internal systems, rogue extensions represent a critical risk. Lockfy Enterprise provides complete visibility into, and control over, browser extensions across Chrome, Edge, Brave, Firefox and Opera, per user and per profile.

How It Works

Lockfy continuously inventories browser extensions on every managed workstation, providing centralized visibility and risk assessment capabilities.

Capability	Description
Full Extension Inventory	Complete list of all installed browser extensions across Chrome, Edge, Brave, Firefox and Opera
Every User, Every Profile	Extensions are inventoried for every browser profile of every user on the workstation
Extension Blocking	Block an extension from the portal and Lockfy enforces the block on every managed workstation through each browser’s own policy
Personal Profile Coverage	Blocks are enforced even in Edge profiles signed in with a personal Microsoft account, where standard Edge policies don’t apply
Browser Restart Action	For browsers that only read policy on startup, Lockfy can restart them so a new block takes effect immediately
Live Updates	Inventory updates as extensions are installed, removed, enabled or disabled, and every change can be sent to your SIEM
Risk Identification	Identify potentially malicious, high-risk, or non-compliant extensions instantly
Violations Report	At-a-glance report of every workstation and profile running a blocked or non-compliant extension
