The 250 users of the trial license will be assigned to your DNSWatch account. The trial license expires after 60 days, but you can renew it once to continue services for an additional 60 days. There are two types of WSM licenses that allow you to manage your WatchGuard Firebox or XTM devices centrally. All licenses must be activated before use. To activate a DNSWatchGO test license for your account: as described in the table below, the number of devices that can be managed for free with these licenses varies depending on the model of the device. To manage additional devices, you can purchase a license upgrade pack. If you activate for the first time a data storage license compatible with a specific firebox model, it will be added as a new license. If you activate a second license compatible with the same Firebox model as an existing license, you can add it as an option as a new license. Each WatchGuard Firebox, XTM or XTMv customer can use WatchGuard System Manager (WSM) to set up and manage a single device without a WSM license. To be able to use WSM`s core management functions, a WatchGuard System Manager license is required.
