Deeper fraud detection

Risky phone numbers or disposable email addresses - we catch them all

Our solution is solely focused on one of two elements: phone numbers or email addresses.

After years of study and research about online fraud patterns, one lesson became abundantly clear: the common element tying near all online fraud attempts has always been the use of disposable emails or phone numbers.

As a result, Defastra has developed disruptive algorithms that quickly identify disposable and risky email addresses or phone numbers accurately.
