A Clear Score

Neustar IP Reputation enables you to understand the risk associated with the IP address being used to originate online transactions. This means you can detect malicious online activity, quickly and easily, without losing good business or adding friction your customer’s experience.

Neustar uses a simple rating system to rank the risk of online activities, based on an IP address, from low to high risk. Whether you are an online merchant, content provider, online gambling/gaming operator, or authorization service, identify risky transactions and determine if you should allow, review or block a transaction. With IP Reputation you're in control.

IP Reputation

Neustar’s IP Reputation transforms static IP data and behavior patterns into a global authoritative source of risk scoring data on IP addresses worldwide. Neustar's reputation decisioning data is based on insight from billions of queries we see per day across markets including financial services, streaming media/OTT content distribution, advertising, insurance, gaming, government, healthcare and more. This ensures that when a decision is made to identify an IP address as risky, that decision will be made using the most insightful IP reputation data available.

Two Powerful Scores

Real-User Score

We assign a score between 1 and 5. To arrive at this score, we analyze usage patterns across key industries as well as collection of non-human activity (e.g. server and botlists) to differentiate real end-user (human) traffic from non-human (bot) traffic. The higher the number (e.g. 5), the more likely the traffic is "non-human".

Risk Score

We assign a risk score between 1 and 100. This score provides insight about the risk of the IP address being associated with malicious activity from IP threat intelligence sources. The higher the risk score (e.g. 100), the more likely the IP has been associated with nefarious activity.
