Our customers are trying to understand when accounts are performing suspicious activities. They need to determine if the user identity is who they’re claiming to be. IP address data is a really good indication of that.

Because our whole system is built around those principles of identification and attribution, we can’t use public information via RIR or other providers. Developing this caliber of data takes a lot of thought and intentional improvement. It’s really quite difficult. There’s a lot of value in having IP data delivered as a service.
