Cisco DefensePro X400 200G DDoS Software License

Keep essential services reachable when attack traffic spikes. Cisco DefensePro X400 - 200G DDoS Software License provides licensing for 200 Gbps DDoS protection, giving security teams the capacity to address large-scale volumetric events without forcing a redesign of the protection stack. This license is suited for organizations that need to defend customer-facing applications, remote access services, and distributed infrastructure against floods, protocol abuse, and other denial-of-service conditions. It supports a more disciplined approach to availability by helping teams maintain control during high-pressure incidents, when every second of delay can affect revenue, operations, and trust. For enterprises standardizing on Cisco security infrastructure, the X400 licensing model aligns protection capacity with demanding network environments. It is a strong fit where attack traffic is measured in hundreds of gigabits and where lower-capacity options would leave too little headroom. That extra margin matters when the cost of downtime is measured in business interruption, not just alerts.
