Contact Us 1:01 Every day, the world generates roughly 2.5 quadrillion bits of data. Neustar isolates certain elements and analyzes, simplifies and edits them to make precise and valuable decisions that drive results. As one of the few companies capable of knowing with certainty who is on the other end of every interaction, we’re trusted by some of the greatest and largest brands in the world to make critical decisions roughly 20 billion times a day. We help marketers send timely and relevant messages to the right people at the right time, using state of the art data analytics and modeling software. We can tell them what ads to serve, and to who and when they should serve them. We’re proud to be the home of some of the most foremost experts on cybersecurity. In a world where cyberattacks are becoming more sophisticated and complex, we have a dedicated team of industry giants that stay ahead of the curve to stave off the next DDoS attack of your network or fleet of IoT devices, all so you don’t have to. Because in our modern connected digital world where customers expect everything to work at all time, if your site or network goes down, not only does your brand image take a hit, it could also mean the loss of millions in revenue. We can authoritatively tell a client exactly who is calling or connecting with them, allowing you to make critical, real-time responses. And the same comprehensive information that enables our clients to direct and manage orders also stops attackers. We know when someone isn’t who they claim to be, which helps stop fraud and denial of service before they become a problem. Because we’re also an experienced manager of some of the world’s most complex databases, we help clients control their online identity, registering and protecting their domain name, and routing traffic to the correct network address. By linking the most essential information with the people who depend on it, we give more than 8,000 clients worldwide the power to make the most well-informed decisions to enable trusted connections between companies and people in their business — not just data they have to figure out and interpret for themselves. Getting identity right begins here.
