Cisco LIC-MX400-SEC-1YR Advanced Security License | Subscription Migration — LIC-MX400-SEC-1YR

Preserve web security coverage during a planned migration with this 600-seat subscription entitlement for Cisco MX400 environments. Built for organizations moving off SurfControl Web Filter, it keeps access aligned to a defined 26-month validation period so security teams can manage transition timing without interrupting service continuity. This license is positioned for controlled upgrades where continuity matters more than a simple renewal. The subscription migration model supports a structured move from legacy web filtering to current security coverage, helping procurement and infrastructure teams standardize licensing while maintaining operational stability. With support for 600 seats, it fits mid-sized user populations that need predictable entitlement management across the migration window. For teams responsible for security operations, the value is in reducing transition risk. Rather than forcing a hard cutover, this license gives you a time-bound path to keep users covered while you complete the migration and validate the new deployment. It is a practical choice when the cost of downtime, policy gaps, or rushed replacement is higher than the license itself.
