Professional USB Device Control & Data Protection

OsMonitor is an on-premise USB device control software for Windows that helps businesses block unauthorized USB drives, enforce read-only access, and prevent data loss through removable storage. As a highly effective USB blocker software, it also works seamlessly as part of a broader on-premise employee monitoring solution for Windows networks.

🔒Block USB

Block USB ports or set them to read-only to prevent illegal file copying.

📝USB Logs

Track every USB insertion, removal, and file movement across the Windows network.

💾Shadow Copy

Schedule automated, compressed backups of important documents to your server.

🎯 Best For:

  • Companies needing to block unauthorized USB drives on Windows PCs.
  • Offices that want read-only USB access instead of outright bans.
  • IT teams requiring on-premise device control without relying on the cloud.
  • Organizations protecting sensitive files from removable media leaks using a dedicated computer monitoring software.

1. Block USB Drives & Control Removable Storage

Using a robust USB blocker software like OsMonitor intelligently manages how removable media is used. It allows you to tailor the security level for each department and prevent data leaks via USB drives.

  • Block Unauthorized USB Devices: Completely disable the use of any external USB flash drive or portable hard drive.
  • Read-Only USB Access: Allow employees to view documents on their USB drive but prevent them from copying work files onto the device.
  • USB Whitelisting: Authorize specific company-issued USB drives by their unique hardware IDs. Only "Approved Drives" will work, while personal storage is blocked.
  • Block Mobile Storage Devices: Specifically target smartphones and tablets (WPD devices) to stop data transfer via mobile sync software.

2. File Shadow Copy (Scheduled DLP Backup)

To further strengthen data loss prevention (DLP), OsMonitor provides a file shadow copy feature that securely backs up your company's documents directly to your local server on a scheduled basis.

Set up document shadow copy schedules, target specific file types, and configure the server storage path.

  • Protect Important Files via Scheduling: A compressed backup of your essential files is saved to your local server periodically, based on the schedule you define (e.g., hourly or daily).
  • Target Specific File Types: Tell OsMonitor exactly which file extensions to protect (such as *.DOCX, *.XLSX, or source code files).
  • Smart Incremental Backup: OsMonitor zips the targeted files using an incremental method, saving bandwidth across the LAN network.

3. USB Audit Logs & File Activity Monitoring

Maintain a transparent record of how sensitive information is handled. As part of a complete employee activity monitoring software solution, OsMonitor logs every file movement and USB connection on the network.

  • Track USB Insertion and Removal: Log every time a USB flash drive is plugged in or unplugged, identifying the specific Windows account and drive letter.
  • File Transfer Monitoring: Accurately record when an employee creates, copies, renames, or deletes a file. The server logs the exact timestamp, IP address, and the full file path.

❓ USB Control FAQ

What is a USB device control software?

It is a security tool that allows IT administrators to manage, monitor, and block external storage devices (like thumb drives and smartphones) from connecting to company computers, preventing data theft.

Do I need to configure every PC manually?

No. All security policies and USB control settings are managed centrally from the OsMonitor Server. You can assign different permission levels with a single click, and the settings will apply instantly across the network.

Does the USB blocking rely on Windows Registry or GPO?

No. Unlike simple scripts or GPO tricks that can easily be bypassed by tech-savvy users, OsMonitor uses memory-based dynamic interception. It does not rely on registry keys or group policies, providing much more robust protection for your company data.

Will blocking USB disable my keyboards and mice?

Not at all. OsMonitor specifically targets USB Mass Storage Devices (like flash drives and portable hard disks). Your standard USB peripherals, such as keyboards, mice, and printers, will continue to work normally without any disruption.

Can OsMonitor support read-only USB mode for specific departments?

Yes. Using group-based policies, you can assign read-only USB access to certain departments while completely blocking USB drives for others, all managed from a central server.

Can OsMonitor recover files deleted by employees?

Yes, provided the file was backed up during the last scheduled cycle. By configuring the file shadow copy feature, the system performs periodic (scheduled) compressed backups of important documents to your local server, allowing you to restore previous versions if they are deleted.
