The Team

DDoS attacks are steadily becoming more sophisticated and network operators need to know that the people behind the DDoS protection products are capable of rapidly developing and implementing solutions in the face of new attack methods. The RioRey management and engineering team has decades of networking experience and most of its key developers have been with the company for five years or more. This is the team responsible for protecting public and private networks and hosting sites across North America and EMEA since 2006.
