SquareX is now part of Zscaler. Where Legba fits
Zscaler acquired SquareX in February 2026. Compare the Zscaler path with Legba's Chrome extension. See differences in buyer, deployment, and price.
Zscaler acquired SquareX on February 5, 2026. SquareX also announced that it joined Zscaler. The practical comparison is now Zscaler versus Legba. We build Legba. Keep that interest in mind.
The market changed
SquareX remains useful historical context. It is not a normal independent buying option today. Its public Chrome Web Store listing is unavailable. Current capabilities, packaging, and prices belong to Zscaler.
Legba remains an independent Chrome extension. The comparison should therefore start with the buying path, not a frozen feature list from before the acquisition.
Current-state comparison
| Dimension | Zscaler | SquareX | Legba |
|---|---|---|---|
| Current status | Enterprise security platform and current owner of SquareX. | Part of Zscaler. The former public extension listing is unavailable. | Independent Chrome extension. |
| Buyer path | Evaluate the current platform with Zscaler. | New buyers should use current Zscaler material. | Install from the Chrome Web Store. |
| Published price | No self-serve price compared here. | Historical prices are not treated as current. | $10 a month, or $100 a year. |
| Browser job | Verify current capabilities and packaging with Zscaler. | Historical product context only. | Ghost gives a private route. Shield opens a page in an isolated browser off the device. |
| Agent path | No claim made in this comparison. | No claim made in this comparison. | Ready skill for browser routing and isolated browser sessions. |
When the Zscaler path fits
Start with Zscaler when browser controls are part of a broader enterprise platform evaluation. This is especially sensible when your organization already standardizes on Zscaler and needs its commercial, deployment, and support model.
Use current Zscaler documentation for architecture and policy details. This page does not rank isolation strength, latency, global reach, or data controls without comparable current evidence.
When the Legba path fits
Legba is a Chrome extension with two modes. Ghost gives you a private browser route. Shield opens a page in an isolated browser off your device.
Choose that path when you want the published self-serve extension and its two browser modes. The extension costs $10 a month, or $100 a year. Agent builders can use a ready skill for the same browser routing and isolation. It does not host the whole agent.
Legba does not claim browser data loss prevention, a team dashboard, or a separate managed-service tier in this comparison. It also does not publish a separate price for the agent skill.
A simple decision
- Use Zscaler when the decision belongs to a broader enterprise platform evaluation.
- Use Legba when you want the current self-serve Chrome extension.
- Treat old SquareX feature and price claims as historical until Zscaler republishes them.
