Cisco Cat 4K/6K Advanced Security Subscription, 3-Year Term | Licensing — C1S1-3Y-CAT4K6KS5

Keep Cat 4K/6K security coverage in place for a full 3-year term with a Cisco subscription aligned to long-horizon infrastructure planning. This entitlement is designed for organizations that want to preserve protection continuity, simplify renewal management, and maintain a clear support posture across the deployment lifecycle. For enterprise teams, subscription-based security coverage helps reduce gaps that can appear when point products age out or procurement cycles drift. A 3-year term also supports budget planning by locking in a defined coverage window, which is especially useful for distributed environments where operational consistency matters more than short-term purchasing flexibility. This offering is best suited to infrastructure owners who already standardize on Cisco and need a clean way to extend advanced security coverage for Cat 4K/6K deployments. It provides a practical path to keep critical systems under active entitlement while avoiding the overhead of piecemeal renewals.
