Cisco Cat 4K/6K Advanced Security Subscription 5-Year Term | Licensing — C1S1-5Y-CAT4K6KS2

Keep Cat 4K/6K environments covered with an advanced security subscription designed for a 5-year term. This licensing model is built for organizations that prefer predictable, multi-year planning and want to maintain security entitlement continuity across supported Cisco platforms. For enterprise infrastructure teams, the advantage is operational clarity. A longer term reduces renewal frequency, simplifies procurement, and helps keep security coverage aligned with the lifecycle of the deployed hardware. That matters when the network is expected to stay stable, documented, and supportable over multiple budget cycles. This subscription is a strong fit for installed-base deployments where advanced security coverage is part of the standard operating model. It gives procurement teams a cleaner path for long-term budgeting while helping technical teams preserve the licensing posture required to keep the environment consistent and governed.
