Cisco ASR 9000 MACsec 100G Right to Use License | Enterprise Security — S-A9K-MACSEC-100

Protect high-speed backbone traffic with MACsec licensing for Cisco ASR 9000 environments. This right-to-use license enables link-layer encryption on 100G interfaces, helping secure data in transit across carrier, enterprise, and service provider networks where throughput and trust both matter. For infrastructure teams, the value is straightforward: add encryption capability to an existing ASR 9000 deployment without changing the platform footprint. That matters when you need to preserve line-rate performance, maintain architectural consistency, and meet security requirements on critical transport links. This license is a fit for organizations that already standardize on Cisco routing and want to extend protection to high-capacity interconnects. It supports security planning for environments where traffic visibility, compliance, and transport integrity are part of the operating model. Compared with lower-tier alternatives, it is aimed at teams that need MACsec capability aligned to 100G infrastructure rather than generic software coverage. Use it to strengthen trusted links across data center interconnects, WAN aggregation, and provider edge deployments where encryption at scale is part of the design, not an afterthought. Ideal For Encrypting 100G backbone links between data centers Securing WAN aggregation traffic on Cisco ASR 9000 routers Adding transport-layer protection in service provider edge networks Supporting compliance requirements for sensitive routed traffic Why This Product 1 Targets Cisco ASR 9000 deployments rather than generic network platforms 2 Enables MACsec for 100G links instead of basic access-layer security 3 Fits high-throughput routing environments where performance matters 4 Delivered as a right-to-use license for simpler entitlement management
