Become all-knowing.

We're in the business of turning unknowns into knowns. Answer the important questions that enable you to stay secure while operating fast.

  • Know if there's anomalous system activity.
  • Know who is logged in, where they're coming from, and what they're doing.
  • Know what processes are running, and why.
  • Know what happened on that transient instance 4 weeks ago.
  • Know what DNS and network traffic each process is generating, and if it's outside the norm.

Know your attack surface.

You can't protect against attacks you can't see. Every time you deploy Threat Stack using your favorite automation system, you gain the visibility needed to improve your security posture.

Boost your confidence & security.

With Threat Stack recording changes in real-time, you can operate with confidence in case an attack makes it past your defenses. Think of it as insurance for your worst-case scenario.


Deep OS Auditing

Make fact-based judgments by examining the trail of logins, processes, network activity, and file changes — fed from the operating system and enhanced with our backend intelligence.

Behavior-based Intrusion Detection

Build up your protection against zero-day attacks with host-level intrusion detection based on behavior changes, not on a signature list.

DVR Capabilities

Record, zoom-in, and playback any user's actions at any point in time, even if the machine no longer exists, using our TTY timeline.

Customizable Alerts

Create custom-tailored alerts around your unique environment. Get notified when an event takes place and respond knowing who, what, when, and where.

File Integrity Monitoring

Our event-driven, real-time, file integrity monitoring allows you to notice changes on key files more quickly, and at a lower system resource cost than previously used techniques.
