Verisign is pleased to announce the transition of our Security Services customers to Neustar

Neustar has a long history of providing a broad portfolio of security services products to enterprise customers including DNS services and DDoS protection. Given this experience, we believe Neustar is well-suited to deliver the innovative solutions and world-class performance to which Verisign’s Security Services customers are accustomed.

Verisign will continue to be dedicated to its core mission of providing critical internet infrastructure, which includes Root Zone management, operation of internet root servers, operation of .gov and .edu, and authoritative resolution for the .com and .net top-level domains, which support the majority of global e-commerce.
