Kyushu Telecommunication Network (QTNet) Protects its Broadband Network and Enhances Reliability With Nominum DNS Security

NominumTM, the DNS-based security and services innovation leader, announced today that QTNet, a subsidiary of Kyushu Electric Power Company in Fukuoka, Japan, has selected the company's DNS solutions to significantly improve the security and performance of its broadband network.

QTNet provides broadband connectivity to millions of households in Kyushu. In particular, the increasing size and number of Distributed Denial of Service (DDoS) and Pseudo Random Sub-domain (PRSD) attacks worldwide has prompted the broadband provider to deploy the Nominum DNS solution in order to thwart network attacks, protect its network and prevent latency and service outages caused by malicious activities. QTNet has replaced its previous costly and less effective DNS solution with Nominum VantioTM CacheServe to speed DNS query resolution and ensure a reliable internet experience for subscribers throughout the region.

"Our brand reputation is closely tied to providing a safe, quality internet experience. Keeping subscribers connected through a secure, fast-performing network is key to maintaining customer loyalty and competing effectively in our market," said Mr. Kenji Mori, Group Manager, Communication Service Engineering Dept. of QTNet. "Nominum was a logical choice to power and protect our network given that it is the top DNS solution among most major operators around the globe. The security and reliability Nominum delivers are already demonstrating a significant return on investment given the improved network performance and higher levels of customer satisfaction we're seeing."

"The rise of DDoS attacks, such as the authoritative DNS attack in late 2016 that took many popular websites offline for several hours, poses high risks for broadband operators whose networks aren't adequately protected," said Jari Heinonen, Vice President Asia Pacific for Nominum. "When subscribers encounter slow network response times or are unable to access their favorite web sites, they're likely to blame their service provider and possibly cancel service. QTNet, like many other providers around the world, is protecting its bottom line and the online experience for subscribers with our industry-leading solution, which also offers cost-efficiency and scalability benefits."
