"SecurityTrails solves the headache of accurately mapping a company's footprint with data you can't find anywhere else. If you are a security analyst or developer, you will get tremendous value from the most current domain intel through their API."
Bill Ladd | Recorded Future
"The SecurityTrails API was not only easy to integrate but the richness of the data really elevated the capabilities of SpiderFoot."
Steve Micallef | Spiderfoot
"We spent a ton of time and effort building out our own domain lists, but we gave up when we found SecurityTrails – the data was better than anything else we've seen, and allowed us to focus on our core product."
Ben Dowling | IPinfo.IO
"We were dreading parsing and storing WHOIS and DNS data until we found SecurityTrailsAPI. We integrated in just a day."
Jonathan Weber | AbuseIPDB
"The wealth of information really is incredible and available through a great API."
Todd Robinson | InMotionHosting
"SecurityTrails is my source of truth when it comes to threat hunting and research. The speed of the API is crazy and the integrations with automation tools and SIEM tools makes it an easy choice."
