# Zscaler Expands Zero Trust Capabilities with SquareX Acquisition for Browser Security

**[Collections](https://daily.dev/sources/collections)** · 1 min read · 0 upvotes · 0 comments

## Summary

Zscaler acquired SquareX to integrate browser-native security into its Zero Trust platform. SquareX's lightweight browser extensions for Chrome and Edge provide threat detection, data loss prevention, content isolation, and real-time monitoring without requiring dedicated enterprise browsers. The acquisition addresses browser security blind spots and strengthens protection for both managed and unmanaged devices, including BYOD environments, against phishing, malicious extensions, and data leakage risks.

## Content

Zscaler has expanded its Zero Trust security offerings through the acquisition of SquareX, a company specializing in browser detection and response. This strategic move enables Zscaler to extend zero-trust security directly into web browsers via lightweight extensions, addressing a significant security blind spot—browsers. SquareX’s technology provides robust browser-native threat protection without the need for dedicated enterprise browsers or complex agents.

SquareX’s browser extension technology is compatible with popular browsers like Chrome and Edge, ensuring security measures such as browser-based data loss prevention (DLP), content isolation, and real-time monitoring. This integration enhances Zscaler’s ability to protect against phishing, malicious extensions, and data leakage risks, including those associated with artificial intelligence, across both managed and unmanaged devices.

The acquisition underscores the strategic importance of browser-native security within enterprise platforms, as seen in similar moves by competitors like CrowdStrike. It also marks a continuation of Zscaler's recent acquisition activity, which includes SPLX, Red Canary, Avalor, and AirGap Networks. By positioning the browser as a critical control point within Zero Trust architectures, Zscaler aims to secure Bring Your Own Device (BYOD) environments and strengthen its Zero Trust Exchange platform.
