Ubiquiti UniFi USG Security Gateway Gigabit Firewall Router VPN DPI | Wty

Ubiquiti UniFi USG — Security Gateway Gigabit Firewall Router

The Ubiquiti UniFi Security Gateway (USG) is an enterprise-grade firewall router with 3x Gigabit Ethernet ports, deep packet inspection, and VPN support — managed seamlessly through the UniFi Network Controller. Designed for UniFi ecosystems, it brings carrier-class routing and security to small and medium business networks. Backed by a 12-month Reboot IT warranty.

Key Benefits

• UniFi ecosystem integration: Managed centrally through the UniFi Network Controller alongside UniFi switches and access points
• 3x Gigabit Ethernet: Dedicated WAN, LAN, and optional LAN2/DMZ ports for flexible network segmentation
• Deep Packet Inspection: Layer 7 application visibility and traffic analysis across all connected clients
• VPN support: IPsec and OpenVPN site-to-site and remote-access VPN built in
• VLAN and firewall rules: Granular network segmentation and access control for secure network architecture
• Scalable management: UniFi controller manages USG alongside access points and switches in one interface

Performance in Use

The UniFi USG is the routing and firewall layer of the Ubiquiti UniFi ecosystem. When managed through the UniFi Network Controller (free software, runs on a server or UniFi Cloud Key), it provides a single-pane-of-glass view of the entire network — routing policies, firewall rules, VPN tunnels, client visibility, and DPI statistics all available from one interface without separate management portals for each device.

The USG handles stateful firewall inspection, NAT, DHCP, DNS forwarding, and VPN in hardware. Its 3 Gigabit ports can be configured as WAN + LAN, WAN + LAN + DMZ, or load-balancing dual-WAN — providing flexibility for network architects designing secure multi-zone environments. DPI provides real-time application-level visibility into traffic patterns across all connected clients.

The USG is ideal for IT administrators who have deployed or are planning a full UniFi stack — switches, access points, and gateway all managed from one controller. It delivers enterprise routing capability at a price point accessible to small and medium businesses, education institutions, and managed service providers.

Frequently Asked Questions

Does it need a UniFi controller to function?

The USG can be used in standalone mode with basic routing, but full features including DPI, VPN, and advanced firewall rules require the UniFi Network Controller. The controller is free software — run it on a PC, Raspberry Pi, or purchase a UniFi Cloud Key or UDM.

Is it factory reset?

Yes. All units are factory reset before dispatch — ready to adopt into your UniFi controller with no prior configuration to clear.

Does it include a power adapter?

Yes — the original power adapter is included.

Can I run dual WAN for failover?

Yes. The USG supports dual-WAN load balancing and failover through the UniFi controller interface — configure one port as primary WAN and the other as failover.

What is the warranty?

All Reboot IT products include a 12-month warranty. If a fault develops within 12 months, we repair or replace at no cost.

What are the shipping costs?

Shipping costs apply based on size and destination — rates are calculated at checkout.
