Block USB File Transfers by File Type

With AccessPatrol’s USB file transfer blocker you can prevent files from being transferred to USB devices based on their name or extension. Prevent data exfiltration by stopping users from transferring unauthorized files to protect sensitive data such as Microsoft Access database files, spreadsheets and executable files.

  • Protect sensitive business data by blocking high-risk file extensions and file names
  • Restrict file transfers to external storage devices
  • Manage custom file blocking policies for each department and endpoint device

Even authorized USB devices used by trusted employees can potentially be misused. AccessPatrol’s Block File Extensions feature provides an added layer of security to proactively prevent employees from transferring high-risk files based on their file types and file names.

Why Use a USB blocker?

  • USB Security: Enforce the exclusive use of authorized USB devices. Combine AccessPatrol’s software-based policies with existing administrative safeguards to prevent employees from using personal USB devices.
  • Prevent Data Breaches: Flash drives are portable and easy to hide. AccessPatrol’s technical safeguards stop insider threats from transferring sensitive data to all forms of removable media.
  • Endpoint Security: USB devices can unknowingly infect company computers with ransomware and other malicious software. AccessPatrol protects these endpoints against rogue USB devices by proactively preventing the transmission of data.

Combine this feature with AccessPatrol’s full suite of USB control features for full control over how removable media and other peripherals are used in your organization.
