Open email attachments with Browser Isolation

You can now safely open email attachments to view and investigate them.

What this means is that messages now have a Attachments section. Here, you can view processed attachments and their classifications (for example, Malicious, Suspicious, Encrypted). Next to each attachment, a Browser Isolation icon allows your team to safely open the file in a clientless, isolated browser with no risk to the analyst or your environment.

To use this feature, you must:

  • Enable Clientless Web Isolation in your Zero Trust settings.
  • Have Browser Isolation (BISO) seats assigned.

For more details, refer to our setup guide.

Some attachment types may not render in Browser Isolation. If there is a file type that you would like to be opened with Browser Isolation, reach out to your Cloudflare contact.

This feature is available across all CES packages:

  • CES_ADVANTAGE
  • CES_ENTERPRISE
  • CES_ENTERPRISE_PHISHGUARD
