WatchGuard

WatchGuard Firebox appliances (in WatchGuard Firewalls) and their subscription bundles. Appliances and licences are sold separately here: a product named “Appliance Only, Licence Not Included” is the hardware on its own, and the Basic, Standard and Total Security Suites are the subscriptions that go with it.
Licences are delivered by email as a key and applied in the WatchGuard console; nothing ships. Not sure which suite covers what you need? Ask before ordering — the difference between Basic and Total is a long list, not a single feature.
