Joyon Entertainment Secures Online Gaming with Juniper Networks


South Korean Provider Deploys NetScreen Firewall Appliances to Protect Entertainment Infrastructure.

SUNNYVALE, Calif., December 15, 2005 - Juniper Networks, Inc. (NASDAQ: JNPR) today announced that Joyon Entertainment (Joyon), one of South Korea’s leading online massively-multiplayer gaming providers, has deployed the NetScreen-5200 and NetScreen-204 firewall/virtual private network (VPN) appliances to protect the company’s gaming network. The Juniper firewall/VPNs replaced Joyon’s previous software-based firewall solution.

“We have upwards of four million users,” said Kon Choi, CTO, Joyon Entertainment. “Online games are fun and excellent entertainment, but when it comes to protecting our users’ information and our network uptime, we’re very serious. Gaming networks have become a popular target for hackers, primarily for stealing financial information, as well as illegally manipulating user accounts. Our earlier deployment of a Linux-based software firewall solution became inadequate as the business grew. With Juniper’s firewall/VPN appliances, we can now confidently scale to our increasing user community and maintain the high-performance gaming experience required for multiplayer environments. In addition, our administrative team also enjoys easier centralized management, lower operational cost and resource overhead.”

As its business expanded and more users accessed the company’s gaming applications, an increasing volume of small data packets on Joyon’s network was overwhelming the in-house developed legacy Linux firewalls. The firewalls were intertwined in a complicated, ad hoc manner, and streamlining efficiency was recognized to be a top priority to maintain high customer satisfaction. Firewall administration became very difficult; therefore, a new solution was sought. The objective was to implement a new firewall system that provided scalability while at the same time increasing protection. Joyon consulted its systems integrator who recommended a two-layer Juniper solution, comprising the NetScreen-5200 and the NetScreen-204 platforms. Joyon thoroughly tested the new system for two months before putting it into full operation.

The NetScreen-204 is part of Juniper’s series of enterprise network security products, designed to easily integrate into many different environments, including medium-to-large enterprise networks, offices, e-business sites, data centers and carrier infrastructures. Joyon’s network topology is characteristic of both a service provider’s and an enterprise’s remote access requirements, and is an ideal network to be protected by the NetScreen-204 that performs firewall functions at wire-speed (even the most computationally intense applications, such as 3DES and AES encryption, are performed at speeds up to 175 Mbps).

Joyon also deployed the NetScreen-5200 that expands on the feature set of the NetScreen-204 to deliver more scalable high performance for large enterprise, carrier and data center networks. It integrates firewall, VPN, DoS protection and traffic-management functionality in a low-profile modular chassis with a switch fabric for data exchange and a separate multibus channel for control information. The NetScreen-5200 provides a first line of defense for Joyon at the network perimeter, while the NetScreen-204 appliances protect the company’s servers in the unlikely event that the perimeter is breached.

“We don’t play games with network security,” said Tim Kang, Juniper Networks’ vice president for Korea. “Our products are designed to thwart a wide spectrum of network attacks, and this is especially important to a market, such as South Korea, with a very high broadband penetration. It is no longer sufficient for businesses to provide merely satisfactory levels of network security, throughput and response. Critical data must be fully safeguarded against abuse and theft.”
