License Expiration Behavior

Network Security Manager (NSM) On-Premises continues to operate for a limited 45-day grace period after an NSM license expires. When any NSM On-Prem license expires, the 45-day grace period automatically begins.

If the license is not renewed before the grace period ends, NSM transitions to a read-only state and firewall management capabilities become unavailable until a valid license is installed.
