Add 400G connectivity support to compatible DefensePro X400 and X800 deployments with this Cisco software license. It is designed for organizations that need to keep pace with growing east-west and north-south traffic volumes while maintaining a security posture built for high-throughput mitigation. For infrastructure teams, this license offers a focused way to expand capability without changing the underlying platform strategy. Instead of introducing a new appliance tier, you can enable the connectivity level required to support demanding production environments and preserve operational continuity as traffic patterns evolve. This entitlement is especially relevant where capacity planning, attack response, and network growth intersect. It helps align the DefensePro deployment with higher-speed infrastructure requirements and supports a cleaner procurement path for teams that need specific connectivity capability rather than a broader platform change.
