    AccessPatrol Block File Transfer Whitelist

    Block File Transfers to Portable Storage Devices

    AccessPatrol is a USB locker tool that prevents data theft via USB ports by restricting removable storage access and limiting the file types that can be copied to removable disks.

    • Prevent copying files that are high-risk based on their filename, keywords in the filename, or file extension
    • Restrict file transfers to external storage devices
    • Manage custom file blocking policies for each department and endpoint device
    • Enable the Allowed List to limit data transfers to storage devices to a set list of filetypes and filename keywords

    Why Use a USB blocker?

    • USB Security: Enforce the exclusive use of authorized USB drives. Combine AccessPatrol’s software-based policies with existing administrative safeguards to prevent employees from using personal USB drives.
    • Prevent Data Breaches: A flash drive is portable and easy to hide. AccessPatrol’s technical safeguards stop insider threats from transferring sensitive data to all forms of removable media.

    AccessPatrol’s USB Drive Device Permission Settings

    AccessPatrol includes various permission settings that a system administrator can use to improve data security without the need to use administrative templates in the local group policy editor.

    • Full Access: The computer or user with this access permission has read and write access to the specified removable device that is connected to the computer.
    • Read Only: USB copy protection will ensure that the user will not be able to copy any information to the specified storage devices; they will only have read access.
    • No Access: AccessPatrol will prevent the users/PC from copying files to the storage devices and restrict access
