Cisco Cat 4K/6K Advanced Security Subscription, 5-Year Term | Enterprise — C1S1-5Y-CAT4K6KS1

Maintain security continuity across Cat 4K/6K deployments with a 5-year Cisco Advanced Security subscription. This term-based license is designed for organizations that want to keep protection aligned with long planning cycles, reduce renewal churn, and preserve operational consistency across installed systems. For infrastructure teams, the value is in control. A multi-year subscription helps standardize security coverage across sites, simplify procurement timing, and avoid short-term gaps that can complicate support planning. It is a practical fit for environments where uptime, policy consistency, and budget predictability matter more than frequent license refreshes. Cisco’s subscription model also supports cleaner asset management over time. Instead of managing repeated annual renewals, teams can anchor security coverage to a longer horizon and focus on operations. That makes this option well suited to enterprise deployments where the cost of interruption, rework, or fragmented coverage is higher than the license itself.
