Cisco Cat 4K/6K Advanced Security Subscription 5-Year Term | Enterprise Licensing — C1S1-5Y-CAT4K6KS6

Strengthen security coverage across Cisco Catalyst 4K/6K deployments with a 5-year Advanced Security subscription built for long-term operational planning. This entitlement is designed for organizations that want to maintain consistent security coverage on supported switching platforms while reducing the churn of short renewal cycles. For network and procurement teams, the advantage is predictability. A 5-year term supports multi-year budgeting and helps keep security coverage aligned with the lifecycle of the installed hardware. That matters in environments where access infrastructure must remain stable, supportable, and ready for ongoing policy enforcement. This subscription is a focused fit for Catalyst 4K/6K environments that already have a defined security strategy and need to extend that coverage through a single, longer-term agreement. It is well suited to campus and branch networks where continuity, planning discipline, and platform alignment are more valuable than piecemeal licensing.
