Protect critical network security services with redundant power support built for WatchGuard M395, M495, M595, and M695 appliances. The WG9037 is designed to maintain operation if the primary power supply fails, helping keep firewall, VPN, and inspection workloads available when uptime matters most. For infrastructure teams, redundancy is not a luxury — it is a control point. Adding a matched spare power supply reduces the chance that a single hardware fault takes an appliance out of service. That matters in branch offices, distributed enterprises, and remote sites where replacement windows are limited and every interruption has a cost. This power supply is intended for supported WatchGuard appliance deployments and should be selected when continuity, serviceability, and platform alignment are priorities. It is a practical choice for teams standardizing on WatchGuard hardware and looking to preserve resilience without overbuying capacity they do not need.
