PRODUCT OVERVIEW
The Cisco
®
Guard XT 5650 DDoS Mitigation Appliance from Cisco Systems
®
delivers a powerful and extensive distributed denial-of-service
(DDoS) protection system. Designed to meet the performance and scalability requirements of the largest and most demanding enterprise
environments, the Cisco Guard XT provides unprecedented levels of protection against today’s increasingly complex and elusive attacks.
Featuring two Gigabit Ethernet interfaces, a single Cisco Guard XT can process attack traffic at line rates as high as a full gigabit-per-second
(Gbps). Working together, multiple Cisco Guard XTs can incrementally scale to support multi-gigabit rates, delivering an extensible solution
that easily adapts to large and growing enterprise environments.
DDoS Attacks Evolving
Today’s DDoS attacks are more malicious, more virulent, more destructive, and more focused than ever. Launched by disgruntled users or
unscrupulous businesses targeting specific sites or competitors, these attacks easily elude and overwhelm the most common defenses.
Composed of legitimate-appearing requests, massive numbers of “zombies” and spoofed identities that make it virtually impossible to identify
and block these malicious flows, DDoS attacks literally paralyze their victims and prevent them from conducting business, costing billions of
dollars per year in lost revenue.
The Cisco Guard XT defends against this new wave of DDoS attacks, enabling businesses to defeat these attacks without compromising their
mission-critical and revenue-bearing operations. Based on a unique multiverification process (MVP) architecture, the Cisco Guard XT employs
the most advanced anomaly recognition, source verification, and anti-spoofing technologies to identify and block individual attack flows while
allowing legitimate transactions to pass. Combined with an intuitive, graphical user interface (GUI) and extensive multilevel monitoring and
reporting designed to provide a comprehensive overview of all attack activity, the Cisco Guard XT delivers robust and comprehensive DDoS
defense for protecting business operations.
