Cisco DefensePro 20-4 DDoS Software License | Security Software, Cisco — CON-ECMU-RDDP204

Maintain service availability when attack traffic spikes with Cisco DefensePro 20-4 DDoS software licensing. Built for organizations that cannot afford downtime, this license supports the mitigation capabilities needed to detect, absorb, and respond to distributed denial-of-service events before they affect users and business operations. For infrastructure teams, the value is in preserving continuity under pressure. DefensePro helps reduce the operational burden of reactive defense by giving security and network teams a structured way to address malicious traffic patterns across critical services. That matters when public-facing applications, remote access, or customer portals must remain reachable during sustained attack conditions. This SWSS upgrade license is suited to environments already standardizing on Cisco security tooling and looking to extend coverage for a specific DefensePro deployment. It is a software entitlement, not hardware, so procurement stays focused on licensing alignment, support continuity, and the protection requirements of the environment rather than appliance replacement. Choose this license when uptime, response speed, and predictable security operations matter more than basic perimeter filtering. It is designed for teams that need a defensible path to keep services available without adding unnecessary complexity. Ideal For Renewing support and entitlement for an existing Cisco DefensePro deployment Protecting internet-facing services from distributed denial-of-service attacks Maintaining availability for customer portals and remote access services Standardizing DDoS defense licensing across Cisco security infrastructure Why This Product 1 License-based protection for existing Cisco DefensePro environments 2 Focused on DDoS mitigation rather than general-purpose security software 3 Supports support continuity through SWSS upgrade coverage 4 Better fit for Cisco-standardized security operations than standalone tools
