Curation Review
✔ Pros:Lowest-cost Ubiquiti gateway with 5 Gbps IDS/IPS, rated above the UDM-SE's 3.5 Gbps at a lower launch price ($279 MSRP vs. $499); Multi-gig flexibility with 10GBASE-T, dual SFP+ and four 2.5GbE ports; Compact desktop design with optional NVMe storage for UniFi Protect/NVR use; Supports site-to-site VPN plus OpenVPN, WireGuard and L2TP server functions, with integrated PoE+ for one device; Managed through the UniFi Network controller with 500+ simultaneous user capacity
✘ Cons:No official routing, IPsec or WireGuard throughput figures published by Ubiquiti; community WireGuard numbers (around 400-500 Mbps) are unverified; Only one PoE+ output port (30W total) versus eight PoE ports on the UDM-SE; Lower device and user capacity and less storage expansion than the UDM-SE; No published IPsec tunnel or concurrent session limits; Reseller prices now often run above the launch MSRP (about $320-$346 USD at US resellers)
✔ Pros:25G SFP28 and 10G SFP+ uplinks at a gateway price point; 23.5 Gbps routing throughput; 1 million concurrent sessions; 18-core ARM CPU with 16 GB RAM; hot-swappable redundant PSUs; supports 500+ UniFi devices and 5,000+ clients; manages through UniFi Network controller with a single pane of glass
✘ Cons:IPsec VPN throughput of 580 Mbps is low for a gateway at this price; IDS/IPS throughput of 12.5 Gbps halves routing performance when threat inspection is enabled; SSL/TLS inspection is limited to about 10,000 concurrent sessions; port configuration differs across listings and should be verified; frequently out of stock at major US retailers, with a $170 memory surcharge at some resellers; no built-in Wi-Fi, so it depends on separate UniFi APs and switches; reviewers cite a steeper learning curve than consumer-grade routers
