Cisco NX-OS Security for XF Nexus 3K | 3-Year License, Network Security — N3K-SEC-3Y

Protect Cisco Nexus 3K switching environments with NX-OS Security for XF Nexus 3K. This licensed software package is built for organizations that need security capabilities aligned to the NX-OS operating system on Nexus 3K hardware, not a generic add-on that only covers the basics. For infrastructure teams, the value is in keeping security functions close to the platform. A license like this helps standardize how security features are enabled and maintained across supported switches, which matters when you are managing access, policy consistency, and operational risk at scale. The 3-year term also gives procurement and engineering teams a clear planning window for budgeting and lifecycle alignment. This is a Cisco software entitlement, so it fits environments where the switching platform is already established and the goal is to extend capability without replacing hardware. That makes it a practical choice for enterprise networks that need to protect existing investment while maintaining a supportable security posture. When the switch layer carries business-critical traffic, platform-specific security licensing is often the difference between basic operation and controlled operation.
