Cisco ASR 9000 MACSEC 40G Right to Use License | Router Security

Protect high-value traffic paths with MACsec enablement for Cisco ASR 9000 platforms. This right-to-use license activates link-layer encryption for 40G interfaces, helping preserve confidentiality and integrity across transport segments that carry sensitive enterprise, carrier, or interconnect workloads. For teams operating at scale, MACsec adds a security layer at the port level without introducing a separate appliance or redesigning the routing architecture. That matters when you need to harden links while keeping the operational model consistent across existing ASR 9000 deployments. It is a practical fit for environments where encryption must be applied close to the wire and where uptime, performance, and policy consistency all carry real cost. Because this is a right-to-use license, it is suited to organizations that already own the platform and need to activate a specific capability on demand. That makes it a targeted purchase for infrastructure teams standardizing security controls across critical 40G paths, especially where compliance requirements or customer commitments call for stronger link protection. The result is tighter control over traffic exposure with minimal disruption to the network design.
