WatchGuard Fireware at a glance
WatchGuard Fireware is the operating system running WatchGuard Firebox security appliances — firewalls and UTM devices popular with SMBs. WatchGuard ships Fireware releases plus security fixes; as perimeter security devices, prompt, careful patching is essential.
For admins updates run through the appliance management (Fireware Web UI or WatchGuard System Manager) — back up the configuration first, and in HA pairs mind the order so you don't drop connectivity. Never expose management or the mobile-VPN portal to the WAN unprotected, and keep remote-access services patched, since these appliances are targeted. After updating, verify VPN tunnels, policies and connectivity. Track the Fireware version and its support window, and follow WatchGuard's security advisories. Being a firewall, Fireware is both a critical control and a high-value target — treat its updates as security-relevant. Patchletter surfaces new Fireware releases.
