Key Takeaways
  • 01Enterprise browsers (Island, Talon, Microsoft Edge for Business) and remote browser isolation have matured into a serious category. They address real gaps in contractor access, BYOD, and high-trust workforce flows that ZTNA alone does not close.
  • 02Where enterprise browsers fit: contractor and partner access without managed-device requirements, BYOD scenarios where corporate apps run in a controlled browser, privileged-access workstations replaced by privileged browser profiles, web-only legacy apps that need DLP, watermarking, and copy-paste control.
  • 03Browser isolation as the alternative: remote browser isolation runs the browser in a sandboxed cloud environment and streams pixels to the user. Addresses similar gaps with a different operational model — particularly useful for risky-link clicking and unmanaged device access.
  • 04Where neither is the right answer: native applications, performance-sensitive workloads, large-file transfer use cases all sit outside what browser-centric approaches handle well. Use ZTNA, EDR, and managed devices for those.

Where enterprise browsers fit

Browser isolation as the alternative

Remote browser isolation runs the browser in a sandboxed cloud environment and streams pixels to the user. It addresses similar gaps with a different operational model — particularly useful for risky-link clicking and unmanaged device access.
