Cisco Cat 4K/6K Advanced Security Subscription 3 Year | Enterprise Licensing — C1S1-3Y-CAT4K6KS9

Extend security coverage across Cat 4K/6K deployments with a 3-year Cisco subscription built for controlled lifecycle planning. This licensing model helps teams maintain access to advanced security capabilities without fragmenting support across multiple short-term renewals. It is a practical fit for infrastructure groups that need to align protection, budgeting, and asset management over a defined term. For enterprise environments, the value is in continuity. A multi-year subscription reduces renewal churn, supports more predictable procurement, and keeps the security posture tied to the installed Cisco platform. That matters when the network edge or access layer must remain stable while teams manage compliance, refresh cycles, and operational risk. This subscription is suited to organizations standardizing on Cisco Cat 4K/6K hardware and looking for a cleaner way to preserve advanced security coverage over time. It is a straightforward choice when the goal is to protect the installed base, avoid gaps in entitlement, and keep support aligned with the hardware lifecycle.
