Prevent data exfiltration via removable media

Stop unauthorized USB drives from copying sensitive data off endpoints.

Eliminate rogue device risk

Block unknown or malicious USB devices from ever connecting to your systems.

Enforce encryption for regulated environments

Require approved external devices to be encrypted to meet compliance and data protection mandates.

One unmanaged device can carry malware in or carry your data out. Without control, removable media becomes one of the easiest breach paths in your environment. It’s time to decide which devices connect and what they’re allowed to do.

With ThreatLocker USB access control capabilities, you gain precise, policy-driven control over removable media access across your endpoints.
‍

You define:

· Which USB devices are allowed.
· Which users can use them.
· What data can be accessed or copied.
· Whether encryption is required.
‍

If it’s not approved, it doesn’t connect.

Create a default-deny, encrypted-only USB policy.

Allow only approved device serial numbers, approved users, and encrypted drives with read-only access unless explicitly required. The rest of removable media will then be blocked by default. For high-risk teams, restrict sensitive file types like .csv, .pst, and .zip.

Here's how it works:
