Make data exfiltration structurally difficult.

Enforce execution control, device validation, and policy-driven data access across your entire environment to block untrusted software, contain trusted tools, restrict data pathways, and validate every device. When access is policy-bound and denied by default, data theft becomes dramatically harder to execute.

Block untrusted software from running

‍Most data exfiltration begins with something executing. If untrusted software can execute, it can stage data, compress it, encrypt it, or quietly transmit it out of your environment. The fastest way to stop exfiltration is to stop unknown execution in the first place.

Deny unknown scripts and LOLBins by default.

Prevent rogue exfiltration tools from launching.

Stop staging scripts before they access sensitive files.

Contain trusted tools so they can’t be abused

‍So often attackers abuse the applications you already trust. When legitimate tools are allowed to do more than they should, they become the attacker’s launchpad. Application containment changes that. It defines clear behavioral boundaries so trusted software can perform its job. This way, you can keep every application in its lane and break the attack chain before it begins.

Prevent Office from spawning PowerShell.

Block browsers from launching system tools.

Restrict PowerShell from outbound internet access.

Limit applications to approved network destinations.

Enforce granular data access control

‍The more users, applications, or devices can touch your sensitive data, the easier theft becomes in your organization. Granular, policy-driven access control ensures only the right people using the right applications can access the right data, at the right time.

Block unauthorized file transfers.

Enforce read-only where required.

Track every read, write, move, and delete action.

Lock down USB and removable media

‍Removable media remains one of the simplest, fastest ways to bypass perimeter controls and export sensitive files. Without strict policy enforcement, one unknown device can move gigabytes in minutes. Locking down removable media closes that silent exit path before it becomes a breach.

Allow only approved serial numbers.

Default-deny all other USB devices.

Require encryption for external drives.

Log every file copied, tied to device identity.

Secure cloud and SaaS access with device validation

‍Passwords are stolen every day, and tokens are intercepted. And sometimes MFA prompts are approved when they shouldn’t be. Don’t rely on a single layer to hold back a determined attacker. Zero Trust cloud access adds a second, decisive control: the device. Access now will be granted only when the device is trusted and the connection follows an approved path..

Require device validation in addition to identity.

Route cloud access through a secure broker.

Block token replay from rogue infrastructure.

Deny access if device and IP don’t match policy.

Restrict lateral movement with network control

‍Once inside, attackers move quietly from system to system, searching for file servers, backups, and high-value data. In fact, most large breaches expand through lateral movement. With strong network control, you can stop this spread. When every device-to-device connection must be explicitly approved, the network stops being an open highway and becomes a series of guarded checkpoints. Sensitive servers cannot be casually reached and data cannot be quietly siphoned from across the environment.

Restrict file server access to approved devices.

Use dynamic ACLs to validate device-to-device connections.

Prevent untrusted endpoints from reaching sensitive systems.

Default-deny east-west traffic.

Detect abnormal file behavior in real time

‍What if your EDR acted instantly to help prevent data exfiltration. With ThreatLocker realtime threat detection capabilities, we will help you automatically identify abnormal behavior and enforce predefined policies immediately. The moment suspicious activity appears, devices can be isolated, risky processes shut down, and attacker pathways closed, without waiting on human review or cloud delays. Your detection strategy becomes immediate containment.

Detect excessive file reads or writes.

Trigger automatic device isolation.

Shut down suspicious processes.

Maintain continuous compliance visibility

‍Most breaches begin with simple misconfigurations: a forgotten admin account, an overly permissive firewall rule, an unmonitored USB port. Small gaps can create big risks. With ThreatLocker, you gain continuous visibility into those gaps and clear, actionable steps to close them before attackers or auditors find them.

Identify excessive USB permissions.

Detect dormant admin accounts.

Map controls to NIST, CMMC, ISO, and other frameworks.

Flag gaps before attackers exploit them.
