The LayerX Difference: Mitigate Extension Risks Without Blocking Productivity

Browser extensions boost productivity, but come with a risk of compromise. LayerX eliminates risky extensions without disrupting the legitimate ones your users depend on.

All Extension Risks in A Single View

LayerX offers an Extension Security Dashboard that provides a way to view extension inventory, risk levels, and critical alerts, enabling security teams to detect threats and enforce policies in real-time for streamlined control and visibility.

Analyze the Risk of Any Extension with LayerX ExtensionPedia

In the past, organizations had to install browser extensions in their environment (or a sandbox) in order to analyze their risks. LayerX ExtensionPedia allows organizations to analyze any extension, even if it’s not yet installed, with detailed extension risk profiles, permission analysis, developer reputation, and risk scoring, empowering security teams to assess risky extensions with minimal effort.

Complete Visibility of Extension Installation and Usage

LayerX provides visibility to all extensions installed in the organization across all browsers, devices, and users. It maps out key information for each extension, such as the extension’s users, permission scope, category, installation type, source, and more. This allows security managers to get a full view of the organization’s browser extension threat surface.

Comprehensive Data-Driven Risk Scoring

Comprehensive Data-Driven Risk Scoring

LayerX identifies risky browser extensions by analyzing both internal factors like access to passwords, cookies, and user input and external signals such as ratings, downloads, and age.  It combines these signals into a unified risk score, enabling security teams to proactively identify and block high-risk extensions even before they’re installed.

Real-Time Monitoring and Blocking

Real-Time Monitoring and Blocking

LayerX continuously monitors extensions in real time. If an extension suddenly starts exhibiting risky behavior, such as accessing sensitive data or communicating with suspicious domains, LayerX detects and blocks it immediately. This real-time protection helps enterprises respond instantly to evolving and zero-day threats without relying on periodic audits.

Adaptive Risk-Based Policy Enforcement

Adaptive Risk-Based Policy Enforcement

Unlike manual blocklist-based tools, LayerX automates extension security using risk-based classification. Organizations can tailor enforcement from monitoring and warning users with customizable messages, to outright disabling existing extensions or preventing the installation of new ones. Thereby reducing admin overhead and improving governance.
