Keep application traffic moving with the Cisco Alteon D-5820SL Secure - 40G, a platform positioned for enterprise delivery environments that demand controlled access and dependable throughput. Designed for teams that need to protect service availability while maintaining policy-driven traffic handling, it fits deployments where performance alone is not enough. This model is suited to infrastructure teams that value secure application delivery at scale. The Secure designation signals a focus on traffic protection and operational control, making it a stronger fit than entry-level routing hardware when the environment carries business-critical workloads, customer-facing services, or internal applications with strict availability requirements. For procurement teams, the value is in buying a purpose-built platform rather than a generic router. That distinction matters when the network must support predictable service behavior, tighter security posture, and fewer compromises under load. The 40G designation further positions it for higher-capacity environments where throughput headroom is part of the design requirement. Use it where secure traffic handling, enterprise oversight, and consistent delivery are part of the operating standard.
