Ubiquiti UniFi Cloud Gateway Max - Compact 2.5 G Cloud Gateway with NVMe, Multi-WAN & Enterprise Security

The Ubiquiti UniFi Cloud Gateway Max (UCG-Max) is a compact, high-performance gateway device built for modern networks. It supports multi-WAN, advanced security, and integrated gateway functions, all in a sleek desktop form factor. Designed to act as the nerve center of the UniFi ecosystem, it handles routing, VPN, firewall, and NVR storage tasks while supporting a substantial number of devices and clients.

With support for 30+ managed UniFi devices and over 300 connected users, the Cloud Gateway Max enables centralized control of network, Protect, Access, Talk, and Connect applications. It supports selectable NVMe storage, enabling it to serve as an NVR host for video surveillance. Advanced features such as stateful firewall, intrusion prevention (IPS/IDS), content filtering, SD-WAN, policy routing, and full VPN capabilities are built in. The gateway includes a 0.96" LCM status display, supports redundant WAN configurations, and draws just 16.1 W at full operation.
