Email security - 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: Turn on Allow users to open a remote browser without the device client 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 these Email security packages: Advantage Enterprise Enterprise + PhishGuard
