A Zscaler alternative for personal isolation.

Zscaler and Legba both touch browser isolation. Their intended operating scale differs sharply. Zscaler protects managed workforce browsing. Legba serves an individual Chrome workflow.

That distinction prevents feature-table confusion. Zscaler offers several deployment forms. Each form serves enterprise policy. Legba offers two personal browser modes.

Existing ZIA or ZPA customers gain context. Their policies already live in Zscaler. Replacing that context creates switching work. Legba does not recreate it.

Some visitors need a smaller result. They want one page isolated remotely. They do not need workforce governance. Legba fits that narrower job.

Zscaler now uses Zero Trust Browser. Older materials may say Zscaler Isolation. The current name covers broader capabilities. It includes three distinct form factors.

The cloud browser handles remote isolation. A browser extension adds local controls. An enterprise Chromium browser adds governance. Buyers can select by use case.

The cloud form creates a remote container. A Chromium engine loads the requested page. Zscaler converts the rendered experience into images. Those images reach the local browser.

Remote containers are temporary by default. Manual logout destroys the container. Idle sessions also expire automatically. Administrators can enable persistent state separately.

Legba gives Chrome users two modes. Ghost provides a private browser route. Shield opens pages off your device. Both begin through one extension.

This narrow shape lowers starting effort. One user avoids platform selection. The user picks a browsing mode. Other device traffic remains unchanged.

Legba does not provide three form factors. It lacks an enterprise browser. It lacks Zscaler posture integration. It lacks ZIA and ZPA parity.

Those gaps matter for enterprise buyers. They matter less for one person. The job decides whether they matter. Legba should never hide that boundary.

Every form factor adds a decision. Every policy adds operating weight. That weight is useful when required. It becomes waste when unused.

The worksheet begins with required outcomes. It does not reward larger feature counts. Each row names the smallest credible fit. Unknown requirements stay visible.

Zscaler's cloud browser keeps web content remote. It suits installs that remain impractical. It also supports controlled application access. Enterprise policies still govern the session.

The browser extension keeps familiar browsers. It adds browser detection and response. It also adds data and posture controls. This form does not equal remote isolation.

The enterprise browser standardizes Chromium. It supplies the deepest browser governance. That control requires browser adoption. Change management becomes part of deployment.

Legba offers none of this selection. That simplicity is intentional. Ghost handles the browser route. Shield handles an off-device page.

Zscaler publishes useful operational limits. File uploads and downloads allow 1 GB. Image clipboard data allows 3 MB. Text clipboard data has no limit.

Each user gets ten active sessions. Idle sessions expire after ten minutes. Default expiry removes isolated content and state. Persistent state changes that behavior.

Persistent state stores selected session information. Zscaler encrypts that state in its cloud. Unused persistent data expires after 15 days. Stored state cannot exceed 100 MB.

These numbers shape real workflows. Large files need direct testing. Long idle tasks need planning. Shared expectations prevent avoidable support tickets.

Zscaler connects browser policy with Zero Trust. It integrates with ZIA and ZPA. Device posture affects application access. Data controls follow enterprise policies.

The product also handles file workflows. Secure previews keep files inside the browser. Sandbox integrations can inspect supported files. Administrators decide allowed outcomes.

Its broader platform supports mixed needs. One user may need remote isolation. Another may need browser extension controls. A third may need dedicated governance.

Legba does not compete across those jobs. It lacks posture checks and DLP. It lacks enterprise browser administration. Zscaler wins when those controls matter.

Zscaler publishes platform bundles and module details. Both current bundles include standard Cyber Isolation. Advanced isolation adds more controls. Exact dollar pricing remains unpublished.

Current standard packaging lists 100 MB. Advanced packaging lists 1.5 GB monthly. That allowance can reach unlimited service. Buyers need current contract details.

Legba publishes extension pricing and a trial. Buyers see its entry terms immediately. That simplifies personal evaluation. It does not price enterprise controls.

Do not compare unmatched plans. Include traffic allowances and required controls. Include support and deployment work. Then compare the complete buying scope.

A fair evaluation begins with requirements. Start with users and managed devices. Then list private application needs. Add posture and data controls.

Next choose the Zscaler form factor. Test only the form under consideration. Cloud results cannot prove extension behavior. Extension results cannot prove cloud behavior.

Test critical files and long sessions. Test authentication and private applications. Measure administrative setup time. Record which policies remain necessary.

Evaluate Legba only for personal scope. Do not recreate the enterprise program. Test Ghost and Shield separately. Keep missing controls marked clearly.

Choose Zscaler for enterprise browser governance. Its three forms cover wider needs. ZIA and ZPA integration add context. Published limits support precise testing.

Evaluate Legba for personal Chrome isolation. Its extension reduces the first decision. Ghost supplies private browser routing. Shield opens pages off your device.

Do not call this full replacement. Keep Zscaler where workforce controls matter. Test Legba for the smaller job. Stop when one required control disappears.

The best system matches actual operations. More forms are valuable when used. One focused extension wins when sufficient. Scope should settle the argument.
