How does ThreatSTOP Work?

What People Are Saying

"Using ThreatSTOP Shield, we were able to set and enforce custom policies and immediately begin blocking unwanted traffic—spam and DDoS attacks—with little or no false positives. This also eliminated threat actors’ attempts to gather information via scanning. Overall network traffic was reduced by 25 percent, which freed up our other security devices to work on more elusive threats. In addition, ThreatSTOP Shield helped us to control threats brought onto the network via BYOD devices."

- Todd Wolfe, Site Director, Meta Solutions -- Athens

"We evaluated a couple other solutions, however, when you consider the cost of the competition vs the benefits, it simply made sense to go with ThreatSTOP. The reality is that we felt ThreatSTOP met and exceeded our expectations, and we really liked the fact that it was easy to use, easy to implement and easy to maintain."

- Kenneth Compres, the Sr. Information Security and Integrations Engineer -- Hillsborough Community College
