Cisco Cat 4K/6K Advanced Security Subscription, 3-Year Term | Security — C1S1-3Y-CAT4K6KS8

Keep Cat 4K/6K access control environments under active security coverage with a 3-year Cisco subscription term. This license is built for organizations that need to preserve policy continuity, reduce administrative churn, and keep security entitlements aligned to deployed hardware over a defined planning window. For infrastructure teams, the value is in operational certainty. A multi-year term helps standardize procurement cycles, simplify renewal management, and avoid gaps that can complicate compliance or support planning. It is a practical fit for sites where access security is part of a broader network governance model and where consistency matters more than short-term purchasing convenience. Because this is a Cisco subscription tied to the Cat 4K/6K security stack, it is suited to environments that already depend on that platform and want to keep licensing aligned with the installed base. The result is a cleaner lifecycle for security coverage, with less time spent reconciling entitlements and more time focused on maintaining controlled access across the network.
