When attempting to apply a VMware Advanced Threat Prevention license key in NSX (or via SDDC Manager), the operation fails with the following error:
Additionally, SDDC operationsmanager.log may show:
The VMware Advanced Threat Prevention key has a licensing dependency. It requires a valid "VMware Firewall" (vDefend) license key to be applied to the NSX deployment first. Without this prerequisite key, the Advanced Threat Prevention key cannot be activated.
Ensure that the VMware Firewall license key is applied before attempting to add the Advanced Threat Prevention key.
