Ubiquiti UniFi Security Gateway PRO 4-Port / Firewall / VLAN / VPN / QoS / 19” / 2x SFP / USG-Pro-4

The UniFi Security Gateway PRO 4 extends the UniFi Enterprise System with advanced routing and security, purpose-built for growing businesses that demand rack-mountable, fiber-ready network infrastructure. It delivers hardware-accelerated performance through a dual-core 1 GHz processor, enabling sophisticated firewall policies, VLAN segmentation, and site-to-site VPN without compromising throughput. Two 1 Gbps RJ45/SFP combination WAN ports provide flexible fiber or copper uplinks, while two Gigabit LAN ports connect directly to UniFi Switches or other devices. Integrated QoS automatically prioritizes voice and video traffic, ensuring clear calls and lag-free streaming across the network. Deployed and managed entirely through the UniFi Controller software, the USG-PRO-4 benefits from intuitive device detection, provisioning, and centralized monitoring—whether on-site or via cloud/NOC. It is an ideal gateway for enterprises seeking to unify security, routing, and management in a single, scalable platform.
