management systems for major telecommunication companies in 1999 and, after the DDoS crisis in 2003 when many Telcos saw a lot of losses in both business and brand image, CQCloud began providing anti-DDoS Protection solutions including DDoS detection, analysis, and control systems. By providing solutions to Korea's biggest telcos with some of the largest and fastest networks in the world, CQCloud has grown their solutions to offer the reliable monitoring and control system, CQCloud Medusa, which supports both Anti-DDoS Protection functionality and Next Generation Security Information and Event Management (NGSIEM).
