"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."

"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."
