Legba vs Cloudflare Browser Isolation

A Cloudflare alternative for personal isolation.

Zscaler and Menlo are the closest Cloudflare isolation alternatives. Island and Prisma Browser offer managed enterprise browsers instead.

Cloudflare Browser Isolation runs pages in a remote browser. It is an add-on to Cloudflare Zero Trust. Pay-as-you-go and Enterprise plans can add it. Gateway policies decide which traffic is isolated.

Existing Cloudflare One teams should usually keep Cloudflare. For one person, Legba is smaller. Shield opens a selected page off your device.

The short version

A workforce platform can be excellent. It can still be too much. Buy the smallest system that fits.

Free for 30 days. No card required. $10 a month, or $100 a year.

Start with the actual browsing job.

Cloudflare and Legba overlap around isolated browsing. Their operating jobs remain very different. Cloudflare serves managed workforce policies. Legba serves an individual Chrome workflow.

The difference should lead the decision. A larger platform brings broader controls. It also brings more deployment work. Those controls matter only when required.

Some buyers already use Cloudflare One. They gain native policy alignment. Leaving that stack creates avoidable work. Cloudflare usually wins for those teams.

Other buyers need one isolated page. They do not manage workforce traffic. Legba gives that job one doorway. The extension supplies Ghost and Shield.

  • Choose Cloudflare for managed workforce policy.
  • Choose Cloudflare for Gateway integration.
  • Choose Cloudflare for Access integration.
  • Evaluate Legba for personal Chrome isolation.
  • Evaluate Legba for public extension pricing.

What are the alternatives to Cloudflare Browser Isolation?

Cloudflare Browser Isolation alternatives fall into three groups. Cloud isolation runs pages away from the device. Enterprise browsers give users a managed browser. A personal extension serves one person.

Zscaler and Menlo are the closest cloud isolation peers. Island and Prisma Browser take the managed browser route. Both also offer extensions for existing browsers.

Legba publishes this list and sells one entry. Each row reflects the vendor's own product page. Pilot any option against your real workflows.

What Cloudflare actually provides.

Cloudflare executes active page content remotely. JavaScript and plugins run in an isolated browser. Gateway HTTP policies apply the Isolate action. Access applications can also render remotely.

Cloudflare uses Network Vector Rendering. It sends drawing instructions toward the browser. It does not stream ordinary page video. That choice shapes compatibility and bandwidth.

Cloudflare deletes an isolated session after closing. Its network decrypts isolated internet traffic. Cloudflare documents retained Zero Trust traffic logs. Buyers should review those policies directly.

The product is a Zero Trust add-on. Pay-as-you-go and Enterprise plans support it. That packaging signals its intended buyer. It is not a personal extension purchase.

  • Active page content executes remotely.
  • Gateway policies select isolated destinations.
  • Access applications can render in isolation.
  • Network Vector Rendering sends drawing instructions.
  • Closed sessions are automatically deleted.

What Legba does instead.

Legba packages two browser jobs together. Ghost gives Chrome a private route. Shield opens pages off your device. Both start through the Chrome extension.

Legba's shape lowers activation energy. One user installs one extension. The user picks the needed mode. Other device traffic stays unchanged.

The narrow scope creates real limits. Legba does not replace Cloudflare Gateway. It does not replace Cloudflare Access. It does not provide workforce DLP.

The limits make the comparison more useful. Legba fits when enterprise controls are unnecessary. Cloudflare fits when those controls matter. Neither answer works for every buyer.

  • Ghost changes the browser route.
  • Shield opens pages off your device.
  • The extension runs in Chromium browsers.
  • Public extension pricing is available.
  • Enterprise policy parity is not claimed.

Use the deployment-fit ledger.

Feature counts hide the real choice. Deployment context decides most outcomes. This ledger starts with the buyer's job. It then names the cleaner fit.

The matrix is intentionally asymmetric. Cloudflare owns more enterprise controls. Legba offers a smaller personal surface. More features do not guarantee better fit.

Match each job with its documented deployment fit.

Compare deployment paths carefully.

Cloudflare documents six connection methods. Five run inline and keep normal URLs. Traffic and DNS mode needs the Cloudflare One Client. Others forward traffic through proxies or tunnels.

Clientless isolation uses a prefixed Cloudflare URL. It targets unmanaged devices and contractors. Users avoid installing the Cloudflare One Client. The Browser Isolation add-on remains required.

Legba takes a simpler personal route. The user installs the Chrome extension. Ghost and Shield begin inside Chrome. No workforce traffic policy is configured.

Simple does not mean universally stronger. Clientless controls matter for contractor fleets. Inline policies matter for managed workforces. Legba intentionally does not supply either system.

  1. 01

    Count the users.

    Separate one-person browsing from workforce deployment. The operating burden changes immediately.

  2. 02

    List required controls.

    Record identity, DLP, access, and logging needs. Keep every mandatory control visible.

  3. 03

    Test critical pages.

    Use real media and authentication workflows. Document every compatibility limit.

  4. 04

    Compare buying paths.

    Request Cloudflare's current package details. Compare them with public extension pricing.

Keep controls and privacy separate.

Cloudflare provides granular interaction controls. Policies can block copy, paste, uploads, and downloads. They can also block keyboard input and printing. These controls need administrators and policy decisions.

Remote execution does not remove data processing. Cloudflare decrypts isolated internet traffic. Its Zero Trust system retains traffic logs. Buyers should inspect retention settings directly.

Legba's public offer serves personal routing and isolation. It does not publish Cloudflare-style governance parity. It should not inherit enterprise claims. It should not inherit privacy assumptions.

Ask different questions for each product. Cloudflare buyers should inspect policy and retention. Legba buyers should inspect browser fit. Both should test their actual workflow.

  • Isolation and privacy remain different questions.
  • Cloudflare documents traffic decryption clearly.
  • Cloudflare documents Zero Trust log retention.
  • Legba lacks equivalent workforce governance.
  • Review current policies before buying.

Test the pages that matter.

Cloudflare publishes meaningful compatibility limits. Webcam and microphone support remain unavailable. Some WebGL sites may fail. Netflix and Spotify Web Player are unavailable.

Cloudflare recommends a 512 MB maximum per file. Clientless isolation does not support Yubikey or WebAuthn. Plain HTTP sites cannot be isolated. Virtual machines are not supported.

One active window renders at a time. Tabs in one local browser share a session. Audio or video pauses in a background window. Simultaneous multi-window workflows are unavailable.

Documented limits do not make Cloudflare weak. They make evaluation concrete. A documented constraint beats an implied promise. Buyers can test the right workflows.

Legba publishes no matching compatibility matrix here. Do not infer feature parity. Test every required page before switching. Keep Cloudflare when one limit remains unknown.

  • Test WebGL applications before rollout.
  • Test microphone and webcam workflows.
  • Test streaming sites before rollout.
  • Test hardware-key authentication paths.
  • Test multi-window and file workflows.

How much does Cloudflare Browser Isolation cost?

Cloudflare identifies Browser Isolation as an add-on. Its plans page shows no isolation price. Cloudflare asks buyers to contact it about SASE packaging. Existing contracts may shape the real cost.

Legba publishes extension pricing and a trial. Buyers see the entry terms immediately. That transparency suits individual purchasing. Enterprise value still needs matched scope.

Public terms simplify individual evaluation. They do not prove lower enterprise cost. Cloudflare may bundle value across existing services. Only a matched quote answers that question.

Compare the same scope on both sides. Include users, controls, support, and deployment. Exclude features nobody will use. Avoid a false headline-price contest.

  • Request current Cloudflare package details.
  • Count every managed user.
  • Include required policy controls.
  • Use current Legba pricing.
  • Compare equal operational scope.

Where Cloudflare clearly wins.

Cloudflare wins inside Cloudflare One estates. Existing policy context already carries value. Gateway selects the traffic. Access covers private applications.

Cloudflare also wins for centralized governance. Administrators can apply isolation selectively. They can restrict browser interactions. They can support unmanaged contractor access.

Broader browser use also favors Cloudflare. It lists Chrome, Firefox, Safari, and Edge as compatible. Legba runs in Chrome and other Chromium browsers. Mixed-browser fleets need broader support.

Cloudflare's advantages are not minor details. They define Cloudflare's product category. Removing them changes the security program. Legba does not ask teams to pretend otherwise.

  • Keep Cloudflare for Gateway policies.
  • Keep Cloudflare for Access workflows.
  • Keep Cloudflare for workforce DLP.
  • Keep Cloudflare for clientless contractors.
  • Keep Cloudflare for mixed-browser fleets.

The practical verdict.

Choose Cloudflare for enterprise browser policy. Its integrations justify the larger system. Clientless access expands managed coverage. Published limitations support careful testing.

Evaluate Legba for one-person Chrome isolation. Its smaller scope reduces starting effort. Ghost handles private routing. Shield opens pages off your device.

Do not plan a platform migration. First isolate the actual browsing job. Keep Cloudflare's controls where they matter. Test Legba only for the narrower job.

The strongest choice may feel obvious afterward. That is good decision design. Required controls should make the answer. Marketing should not make it.
