Form Factor: 1U fixed chassis, fanless, 1.3 in x 11.81 in x 7.52 in, 3.52 lb (SRX440) / 4 lb (SRX440-2AC); 8 GB DRAM
Curation Review
✔ Pros:Compact 1U fixed fanless design suited to branch offices; 8 RJ-45 plus 2 SFP ports for flexible branch connectivity; Two RJ-45 ports support PoE+ at 30W per port (per one source, not verified on datasheet); SRX440-2AC variant adds a second AC power inlet for power redundancy; Part of Juniper's SRX line with routing and SD-WAN capabilities
✘ Cons:Published firewall throughput of 300-500 Mbps is low for modern WAN speeds; No verified IPsec VPN, session, or new-sessions-per-second figures were found in the sources reviewed; Only 2 SFP ports limits fiber uplink options; Price is high relative to its throughput; Redundant power requires the more expensive SRX440-2AC model
IPsec VPN Throughput: Not published by Ubiquiti; WireGuard/Site-Magic VPN up to 500 Mbps (third-party review, untested method)
Max Sessions: Not published
New Sessions/sec: Not published
Interfaces: 5x 2.5GbE RJ45 (1 WAN + 4 LAN, one LAN port can be remapped to a second WAN)
Form Factor: Compact desktop, 142 x 127 x 30 mm, USB-C 5V/5A power (max 16.1 W)
Curation Review
✔ Pros:2.5GbE WAN and LAN ports on a compact, low-power chassis (max 16.1 W); 512GB built-in NVMe storage on the standard SKU for local UniFi data; Integrated UniFi controller with IDS/IPS and no license or subscription fees; Supports 300+ clients and 30+ UniFi devices; Multi-WAN capable through the remappable LAN port
✘ Cons:Only 1.5 Gbps with IDS/IPS enabled, well below the 2.5 Gbps routing figure; IPsec VPN throughput, session counts and new sessions per second are not published; No PoE output and no built-in Wi-Fi access point; No LAG/LACP support; 500 Mbps VPN throughput is limiting for high-volume site-to-site tunnels
