Cisco ASR 9000 MACsec 40G RTU License | Enterprise Network Security — S-A9K-MACSEC-40=

Keep high-speed backbone traffic protected with MACsec enabled on Cisco ASR 9000 at 40G. This right-to-use license activates link-layer encryption for environments where data confidentiality, integrity, and trusted transport matter across core and edge networks. It is a focused licensing option for teams that need to secure traffic in motion without introducing a separate overlay or redesigning the forwarding path. For service providers and large enterprises, MACsec at 40G helps maintain security controls on critical interconnects, aggregation links, and transport segments where throughput cannot be compromised. The license model fits organizations standardizing on Cisco ASR 9000 infrastructure and looking to extend protection to specific interfaces as policy requires. Because this is a right-to-use license, it supports a controlled deployment approach: activate only where needed, align security investment to the link, and preserve the performance profile expected from carrier-class routing platforms. It is a precise fit for teams that value deterministic operations, compliance alignment, and secure transport at scale.
