Description
Overview
The UniFi Cloud Gateway Ultra (UCG-Ultra) is a compact, high-performance router and network controller that brings enterprise-grade networking to small businesses and home offices. This all-in-one device serves as your network’s central hub, combining routing, advanced security features, and UniFi controller capabilities in a sleek desktop form factor that sits comfortably on any desk or shelf.
Designed for environments with up to 30 UniFi devices and over 300 connected clients, the Cloud Gateway Ultra delivers impressive performance without the complexity typically associated with enterprise networking equipment. Its 2.5 Gigabit WAN port handles high-speed internet connections with ease, while the integrated IDS/IPS security suite provides 1 Gbps of threat-protected throughput—keeping your network secure without sacrificing speed.
What sets the UCG-Ultra apart is its simplicity. Unlike traditional routers that require separate controllers or cloud subscriptions, this device runs the full UniFi Network application locally, giving you complete control over your network through an intuitive interface. The built-in 0.96″ LCM display provides at-a-glance status information, while Bluetooth connectivity enables quick mobile setup.
Key Features
The Cloud Gateway Ultra packs serious networking capability into its compact polycarbonate enclosure. The 2.5 GbE WAN port supports multi-gigabit internet connections, while four 1 GbE LAN ports provide wired connectivity for local devices. Multi-WAN support with load balancing and failover ensures your network stays online even when your primary connection drops—pair it with a UniFi LTE Backup for truly redundant internet access.
Security is handled by a comprehensive threat management suite including stateful firewall, application-aware Layer 7 filtering, deep packet inspection, intrusion prevention with over 55,000 signatures (with CyberSecure subscription), content filtering, and ad blocking. Zone-based firewall rules let you segment traffic by region, domain, or application type, while VLAN support enables proper network segmentation between guest networks, IoT devices, and trusted systems.
VPN connectivity is thoroughly covered with Site Magic for simple site-to-site connections, plus support for WireGuard, OpenVPN, L2TP, and IPsec protocols. The built-in Teleport feature provides zero-configuration VPN access for remote workers, while the Identity Endpoint offers one-click VPN setup for authorised devices. Advanced routing features include OSPF dynamic routing, policy-based WAN routing, RADIUS server with RadSec support, and comprehensive IPv6 support.

Applications
The UCG-Ultra excels in small-to-medium business environments, home offices, and residential networks where reliable performance and straightforward management are priorities. It’s particularly well-suited for businesses running a handful of access points, a switch or two, and perhaps some UniFi cameras—all managed from a single, intuitive interface.
Small retail shops, cafes, and professional offices will appreciate the content filtering and ad blocking capabilities for providing clean guest WiFi, while the VPN server functionality makes it easy to provide secure remote access for staff working from home. The NDAA compliance makes it suitable for government contractors and security-conscious organisations.
For home users, the UCG-Ultra offers a significant upgrade from consumer routers, bringing proper network segmentation, parental controls, and detailed traffic analytics without requiring networking expertise. The compact, quiet operation (no fans, minimal power draw) makes it ideal for living spaces.
What’s in the Box
The UCG-Ultra ships with the main unit, a USB Type-C power adapter (5V/3A), and quick start documentation. The device is ready to configure out of the box using either Ethernet or Bluetooth via the UniFi mobile app.
