Cisco N3K-SEC-1Y NX-OS Security for XF Nexus 3K | Subscription — N3K-SEC-1Y

Keep XF Nexus 3K switching aligned with Cisco security requirements through a 1-year NX-OS Security subscription. This license is designed for infrastructure teams that need a clear entitlement path for maintaining security functionality on supported Nexus 3K deployments. In production networks, security licensing is not just a procurement line item. It determines which capabilities remain available, how consistently policy can be applied, and whether the platform stays aligned with operational standards over time. Choosing the correct Cisco license helps avoid gaps that can complicate audits, delay changes, or force unplanned remediation. N3K-SEC-1Y is a practical fit for organizations standardizing on Cisco NX-OS in the access or aggregation layer. It supports a controlled renewal cycle, simplifies budgeting, and keeps the platform on a known support path. For teams managing multiple switch tiers, that predictability is worth more than a lower-cost alternative that may not map cleanly to the installed base.
