DNS Defense

Block Threats Early, Before the Damage


Everything that happens on the Internet starts with a DNS query. DNS makes connections to mission critical applications, websites, and resources on the network for us. But attackers and malware also rely on DNS for attacks to succeed.

ThreatSTOP enables true Protective DNS (PDNS) with continuous updates from 900+ Threat Intelligence sources. DNS Defense turns your existing DDI/IPAM or DNS Servers into security enforcement points that stop dangerous and unwanted traffic before damage is done.

Our Customers Say:

It also enabled us to quickly track down the infected ultrasound making the calls. That sold the product." - Geisinger Health
  • "ThreatSTOP has eliminated manual blacklisting & remediation, reducing help desk tickets relating to malware by 90%, to only 1 - 2 per month." - University of Baltimore
  • "ThreatSTOP is an effective and easy tool for reducing internet enabled/distributed malware. The price is incredibly fair, even for a non-profit." - Oklahoma Medical Research Foundation
