"Centripetal leads the industry in operationalizing global threat intelligence to proactively protect our CleanINTERNET customers from all known cyber threats. DomainTools has been a valued strategic partner for years, and in 2024, we leveraged over 99.9% of their feed data to prevent domain-related incidents—contributing to our exceptionally low false positive rate across 1.2 trillion indicators. Through close collaboration this year, we were among the first to adopt DomainTools’ Real Time Feeds and API, reducing the time from threat discovery to active prevention to under one minute. This level of speed and accuracy effectively closes the window for domain-based attacks. DomainTools has set a new standard for real-time, high-fidelity intelligence—critical to any modern, proactive defense strategy."

“Iris Investigate’s UI is very well designed and intuitive, so we did not have to have any training before seeing value. If we cannot figure out how to use 80% of a tool without training, honestly we are probably not going to use the tool.”

“We did a trial with four different organizations who claimed to provide similar data. DomainTools had better data and faster notifications to the tune of something like 30% better coverage than the other providers we tested. It was significant and not even a question which we would go with.”
