Previously, Remote Browser Isolation (RBI) limited administrators to allowing or blocking all downloads or all uploads during isolation, regardless of file type. This lack of flexibility forced administrators to choose between allowing all file transfers, which could lead to security issues, or blocking all file transfers, which could result in usability issues and user dissatisfaction.

You can now use isolation profiles in RBI to specify the types of files users can upload or download, enabling more granular control over data transfers during isolated browsing sessions. The new capability helps to enhance the security posture by reducing the attack surface and preventing various types of cybersecurity threats. It also helps in data exfiltration by controlling which categories of file types a user is able to upload.

Key use cases include permitting users to download only document files, blocking downloads of executable files, or permitting transfers of only specific approved file types. The granular controls enable you to balance security and usability by tailoring allowed file types to your organization's needs. Configuring file type filtering enhances your data loss prevention capabilities and provides an additional layer of protection against potential threats introduced through file transfers.
