UBNT USG Overview
UBNT USG is a fixed architecture enterprise router that delivers high-performance routing and integrated security services for small business and branch office environments. The device is powered via an AC power supply and is equipped with a dedicated WAN port alongside two LAN ports using 10/100/1000 Ethernet, ensuring robust, wired connectivity and streamlined network segmentation.
Engineered for secure, efficient network operations, the UBNT USG integrates IPSec, L2TP, and PPTP VPN features with a powerful firewall to safeguard data traffic while maintaining gigabit throughput capacity. Although its design is fixed (non-modular) and does not include built-in wireless support, its comprehensive feature set—comprising remote management via SSH, HTTPS, and SNMP, QoS support, and compliance with CE and FCC standards—renders it ideal for small business deployments requiring dependable performance and security.
