LayerX is a browser security platform that provides visibility and control over user and agentic interactions within web browsers. The solution operates through a lightweight browser extension that works across all major Chromium and Mozilla-based browsers without requiring browser replacement. The platform monitors user activity including browsing behavior, text input, copy/paste actions, file uploads/downloads, printing, and cookie usage. It analyzes risks in real-time and enforces adaptive, risk-based policies directly within the browser environment. LayerX addresses browser-layer security risks including GenAI misuse, web-based data leakage, credential theft, phishing, Shadow SaaS usage, and malicious browser extensions. The platform provides continuous monitoring of installed extensions, evaluating their permissions, behavior, and source. The solution includes an AI Risk Analysis Engine that analyzes the risk of assets and transactions. A centralized management dashboard enables configuration of access and activity policies, browser management, usage monitoring, and audit report generation. LayerX includes anti-tampering capabilities to prevent end users from disabling, uninstalling, or circumventing protections. The platform integrates with identity providers and SIEM systems to aggregate sensor data, collect logging and alerting information, and add threat intelligence layers. The extension acts as both sensor and enforcer, applying protections directly in the browser while maintaining user experience. Policy enforcement ranges from monitoring to warning or blocking actions based on user, device, application, or data type.
