Enterprise Browser Extension

Enterprise Browser Extension installs Netzilo's browser extension to protect data delivered through web applications. It provides real-time protection against web-based threats and unauthorized data access while maintaining a seamless browsing experience.

Overview

The browser extension offers an additional layer of security for users browsing the internet. It monitors and controls access to web applications, ensuring that data remains protected even during online interactions. Unlike full browser solutions, the extension works with existing browsers, making deployment easier and less disruptive.
