After five years of research and market accumulation, NSFOCUS Anti-DoS system brings forward a new high-end product named Collapsar Anti-DoS System Defender 4000 (for short, Defender 4000). Compared with earlier products, Defender 4000 is immensely improved in its multi-level authentication system, high protection capability, dynamic traffic redirection technique, attack monitoring and analysis report, reliability and high availability.
Practice has proved that embedded DoS prevention function of common security products works only for those traditional and characteristic DDoS attacks of small traffic, but cannot correctly detect or prevent DDoS attacks that exploit Botnet or are exquisitely crafted based on the action anomaly. NSFOCUS Collapsar Anti-DoS System, however, detects attacks based on behavior anomaly, filters attack traffic rapidly, and ensures the transition of normal traffic. Moreover, the system can be employed in various network environments to ensure the integral performance and reliability of the network. Defender 4000 of cluster mode enhances the prevention capability of a single anti-DoS device to 4-6G, and easily blocks massive attacks of more than 10G.
Collapsar serials of NSFOCUS are widely used in fields including telecom, finance, energy enterprises and government, protecting the operation of service systems of China Telecom, China Netcom, China Mobile, backbone network of China Unicom, MAN, IDC, and medium and large enterprises, and are favored by financial clients including banks, securities, and insurance as well as deployed in lots of portal websites and e-business websites.
There are plenty of successful applications of NSFOCUS Collapsar serials in various fields. With the marketing of Defender 4000, the users’ anti-DoS capability will be improved greatly and the Collapsar serials will again be regarded as the “Most Favored Brand” of telecom and enterprise users. |
