E-Commerce Marketplace Deploys Juniper's High-Performance Firewall/VPN Appliances to Quickly Meet Its High-Performance Business Requirements

SUNNYVALE, Calif., November 26, 2007 - Juniper Networks, Inc. (NASDAQ: JNPR), the leader in high-performance networking, today announced that Gmarket, one of Korea's leading retail e-commerce marketplaces, is protecting its network infrastructure with the Juniper Networks NetScreen-5400 high-performance firewalls. The NetScreen-5400 handles up to one million concurrent VPN user sessions to secure Gmarket's web servers, network applications and databases, which host highly sensitive e-commerce data.

"As one of Korea's leading e-commerce websites, we retain a tremendous amount of sensitive identity and financial transaction data," said Euiwon Park, Gmarket's IT security team manager. "Our popularity also means managing a large number of concurrent user sessions. To support the growth of our business and protect this sensitive information without compromising network performance, we needed a security solution capable of handling very high traffic demands while also offering superior threat mitigation. The Juniper NetScreen-5400 was the only device in the market that could meet both our stringent performance and security demands."

With more than 13 million registered users and 16 million monthly visitors, GMarket's network is critical to its success. Juniper's purpose-built platform enables GMarket to facilitate the sale of products to a large number of potential buyers in a more convenient, cost-effective and secure manner. Juniper Networks NetScreen-5400 appliances are high-performance firewall/VPN security systems designed to deliver best-in-class performance capabilities for large enterprise, carrier and data center networks. The NetScreen-5400 systems integrate firewall, VPN, traffic-management functionality and protection from attacks such as DoS/DDos, all in a low-profile modular chassis. Built around Juniper's third-generation security ASIC and distributed system architecture, the appliance offers exceptional scalability and flexibility, while providing a higher level of security through Juniper Networks ScreenOS custom operating system. The NetScreen-5400 can scale up to 30 Gbps firewall and 15 Gbps VPN throughput.

"Customers such as Gmarket must simultaneously focus on ensuring the security of the information for which they are entrusted, while also ensuring that the performance of their network can keep pace with customer requirements," said Tim Kang, vice president of Korea for Juniper Networks. "As Asia Pacific's enterprises scale their business models, they require the type of high-performance network infrastructure which Juniper delivers that creates a trusted and responsive environment for delivering new, revenue generating services and can also significantly reduce both costs and exposure to risk."
