We’re Built to Block Threats

Proactive Threat Blocking

Threats should be blocked early, before they become breaches. Over 80% of today’s successful attacks come from well known IP and domain infrastructure used in other attacks. We help you pinpoint and block them.

Choose Your Policy

Leverage the power of over 850 world-class threat intelligence feeds. Control what is blocked, redirected and allowed through rich policy customization. Pick the threat types and appropriate action, add your own white and black lists

Connect Your Devices

No need for new hardware, ThreatSTOP works with devices you already have. Integrating ThreatSTOP with NGFW, Routers, Switches, DNS Servers and more takes just a few minutes. We’ll automatically deliver policy updates to keep you protected.

    We manage a vital resource for millions of people that live, visit and work in southern California, and ThreatSTOP is very effective at protecting our critical IT systems.

  • Healthcare

    We have plenty of other systems in place, but ThreatSTOP prevented an ultrasound machine attack and gave us visibility into a large number of DNS queries that were being blocked. It also enabled us to quickly track down the infected ultrasound making the calls. That sold the product.

  • Non-Profit

    When we began using the product on premise, we immediately saw what was hitting our firewall on a daily basis. Definitely a success story for us. Working with ThreatSTOP really made sense for us from a business standpoint. We have a relatively small IT team for an organization of our size. With ThreatSTOP, we can stay ahead of the hackers.
