Automatically isolate compromised machines and protect your data in real time

Detect abnormal behavior instantly and enforce predefined policies automatically to isolate devices, shut down risky processes, and block attacker pathways in real time.

Contain ransomware before encryption spreads
Detect abnormal file activity and automatically block excessive writes, isolate affected machines, and, within seconds, shut down risky tools like PowerShell.
Stop lateral movement during active compromise
Automatically restrict RDP, block unauthorized network connections, and isolate compromised endpoints before attackers pivot.
Respond instantly to abnormal behavior without waiting on humans
Enforce predefined deny policies the moment suspicious privilege escalation, rogue scripts, or unusual IP connections are detected to reduce dwell time dramatically.
What if your Endpoint Detection and Response (EDR) could act the instant a threat appears without waiting for human or AI intervention? Imagine the peace of mind knowing your data is protected in real time. If a user uploads sensitive files through a browser, a known exploit is triggered, or a process starts behaving abnormally, you want immediate action to contain the threat and minimize impact.

That’s exactly what ThreatLocker delivers:
A fully policy-driven EDR solution that automatically reacts and isolates threats in real time. Powered by the ThreatLocker Zero Trust Platform, it analyzes telemetry and behavior patterns to identify Indicators of Compromise (IoCs) and instantly enforce predefined policies that contain and neutralize threats.
Before we had ThreatLocker, we had a lot of risk that we just couldn't control. Now, we're doing a better of a job of providing a secure environment for our patients, doctors, and manufacturers.

Here’s how it works:

Instantly identify anomalies
ThreatLocker EDR continuously pulls telemetry from your environment and flags activity that falls outside normal behavior: unusual IP connections, rogue applications, abnormal script execution, or unexpected privilege escalation. In a cyberattack, seconds matter and this EDR solution acts immediately, not minutes or hours later.
Powered by real-world intelligence
Leverage a continuously updated library of IoCs maintained by the ThreatLocker Intelligence team. This ensures you keep pace with evolving threats and align with the MITRE ATT&CK framework, creating real-time alerts for your SOC or MDR team.
Automatically respond to limit threats
When our EDR identifies suspicious activity, it can immediately restrict access, shut down risky processes like PowerShell, or block applications attempting unauthorized actions. In the event of a certain compromise, it can automatically isolate affected machines to contain the attack, giving your SOC time to investigate and respond.
In a split second, it isolates devices, triggers alerts, and enforces application, storage, and network policies. It can also integrate with and send alerts to your other security tools, including SIEM or SOAR platforms.

This EDR functionality is backed by a robust catalog of policy actions that respond instantly at the endpoint by:

Automatically activating policies to block or terminate high-risk tools (e.g., PowerShell, Command Prompt), immediately disrupting attacker activity.

Detecting excessive file writes or reads and instantly blocks them to stop ransomware encryption or data exfiltration.

Automatically applying policies to block risky network access, such as RDP.

Responding based on ThreatLocker threat scores, ensuring near-instant, on-device reaction without cloud delays.

Sending alerts, help desk tickets, or making REST API calls for immediate security team action when automated response isn’t enabled.

Your benefits

Stop threats before any damage is done
Instantly detect and respond to abnormal behavior in real time.
Respond instantly during a certain attack
Enforce deny policies, isolate devices, or lock down systems the moment something suspicious happens.
Catch what others miss
Detect insider threats, abuse of legitimate tools, and novel attacks traditional EDRs overlook.
Deep integration with ThreatLocker Zero Trust Platform
Seamlessly trigger Zero Trust policies based on threat activity.
Leverage the power of the community
Tap into and share proven policies from other IT pros and the ThreatLocker team.
Create a predefined containment policy. Excessive file writes? Isolate automatically. Suspicious PowerShell? Terminate instantly. Abnormal RDP or outbound traffic? Block immediately. Decide the response before the attack. Let policy act in real-time.

The results?

No waiting or delays. The moment behavior crosses the line, action is automatic. We will isolate compromised devices and shut down risky tools to stop the spread. So, your team steps in with control to contain the threats.
