Ubiquiti UniFi USG-PRO-4 Security Gateway 4-Port GbE SFP Rack Enterprise Wty

Ubiquiti UniFi USG-PRO-4 Enterprise Security Gateway

The Ubiquiti USG-PRO-4 is a rack-mountable enterprise security gateway delivering 1Gbps routing throughput, dual WAN failover, deep packet inspection, and SFP fibre uplinks — managed via the UniFi Network Controller and backed by a 12-month Reboot IT warranty.

Key Benefits

• 1Gbps Routing Throughput: Line-rate Gigabit routing across four Ethernet ports handles the heaviest enterprise network loads without bottlenecking.
• Dual WAN Failover: Two WAN ports with automatic failover and load balancing keep the network online when a primary ISP link drops.
• SFP Fibre Uplinks: Two SFP ports support fibre uplinks for long-distance runs or high-availability links between network equipment.
• Deep Packet Inspection: Built-in DPI identifies and classifies application traffic — full visibility into what's consuming bandwidth across the network.
• IPsec & OpenVPN: Supports both IPsec and OpenVPN site-to-site and remote-access VPN — secure branch office and remote worker connectivity built in.
• UniFi Managed: Managed from the same UniFi Network Controller console as all other UniFi devices — one pane of glass for the entire network.

Performance in Use

In an enterprise or advanced SMB network, the USG-PRO-4 sits at the WAN edge handling routing, NAT, firewall, and VPN duties with 1Gbps throughput. Two dedicated WAN ports allow dual ISP connections with automatic failover — if the primary fibre link goes down, traffic shifts to the secondary connection automatically, keeping VoIP, cloud applications, and user traffic flowing without manual intervention.

The SFP ports expand deployment options significantly. Long-run fibre connections between buildings or floors are handled natively, and high-speed uplinks to internet edge switches or service provider equipment eliminate copper distance limitations. Deep packet inspection gives IT teams real visibility into application traffic — identify which applications are consuming bandwidth and implement QoS policies accordingly.

VPN configuration through the UniFi controller is straightforward — site-to-site IPsec tunnels and remote access OpenVPN connections are set up within minutes. For organisations already running UniFi switches and access points, the USG-PRO-4 completes the UniFi ecosystem with a unified view of all network devices, clients, and traffic from a single controller interface.

Frequently Asked Questions

How is the USG-PRO-4 managed?

Via the UniFi Network Controller, which can be self-hosted (Cloud Key, NUC, or VM) or accessed via Ubiquiti's cloud console. It integrates with all UniFi devices in a single management interface.

Does it support dual WAN?

Yes. Two of the four GbE ports are dedicated WAN ports, supporting dual ISP connections with automatic failover and load balancing across both links.

What VPN types are supported?

IPsec (site-to-site), OpenVPN (remote access), and PPTP. Configuration is done through the UniFi controller without manual CLI commands.

What is the routing throughput?

Up to 1Gbps in standard mode, approximately 250Mbps with Deep Packet Inspection and IDS/IPS enabled — typical for this class of security gateway.

What are the shipping costs?

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