Cisco NCS 5500 MACsec License for NCS 55A2 Fixed Ports | Enterprise — NC55P-MSEC-55A2

Add link-layer protection to fixed-port NCS 55A2 deployments with the Cisco NCS 5500 MACsec license for 16 ports. This entitlement is intended for organizations that need to secure traffic on high-value network links while keeping the existing platform architecture in place. MACsec is commonly selected when confidentiality and integrity matter at the transport edge, especially in service provider and large enterprise environments where traffic traverses shared or exposed infrastructure. By licensing fixed ports on the NCS 55A2, teams can extend protection to the interfaces that carry critical workloads, inter-site traffic, or backbone flows. For procurement and architecture teams, the appeal is precise scope: licensing tied to the supported fixed ports, with no ambiguity about what is covered. That makes it easier to align security spend with the exact hardware footprint in production and to plan upgrades or expansions with clear port-level control.
