Cisco CAT 4K/6K Advanced Security Subscription 3 Year | Enterprise — C1S1-3Y-CAT4K6KS1

Maintain security coverage on Cisco Catalyst 4K and 6K switching platforms with a 3-year Advanced Security subscription. This term license is designed for organizations that need to keep security capabilities active across the switching layer without changing the underlying architecture or disrupting established operations. For enterprise networks, the value is in continuity. A multi-year subscription helps stabilize procurement, reduce annual renewal overhead, and keep security entitlements aligned to the deployed Catalyst environment. That matters when the switching fabric is part of a larger campus or branch design and security policy must remain consistent over time. This subscription is a strong fit for teams that already run Cisco Catalyst 4K/6K hardware and want a licensing path that supports long-range planning. It is not about adding complexity; it is about preserving the security posture already built into the network and keeping the platform covered through a defined term.
