Maintain security coverage across Cat 4K/6K deployments with a 3-year Cisco Advanced Security Subscription. This term license is built for organizations that want to keep access control and security features aligned with their installed base without managing short renewal cycles. For infrastructure teams, the value is operational clarity. A multi-year subscription helps standardize protection across supported systems, simplifies procurement planning, and reduces the risk of gaps that can appear when security licensing is handled piecemeal. It is a practical fit for environments where uptime, policy consistency, and lifecycle control matter more than chasing the lowest upfront cost. Cisco licensing is often chosen when the environment needs vendor-aligned coverage and a clean path for ongoing supportability. This 3-year term gives procurement teams a defined renewal horizon while helping technical teams keep security posture synchronized with the platform they already run.
