Firewall Throughput: Not published by Ubiquiti; 5 Gbps IDS/IPS-secured routing throughput is the only headline figure (reviewer and retailer listings)
Threat Prevention Throughput: 5 Gbps IDS/IPS
IPsec VPN Throughput: Not published
Max Sessions: Not published; 500+ simultaneous users and 4,000-entry MAC address table
New Sessions/sec: Not published

PoE Budget: 30W total from one PoE+ port (port 4)
Max Power Consumption: 29.4W excluding PoE output
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)
IPsec VPN Throughput: 8 Gbps (1024B TCP, fastpath); ~11 Gbps projected with VPN offload on FTD 7.2
Max Sessions: 2,000,000 concurrent
New Sessions/sec: 130,000 (FTD with AVC); a separate ASA-style table lists 300,000, unverified
Interfaces: 8 x 1G RJ45, 8 x 1/10G SFP+
Form Factor: 1RU appliance
Curation Review
✔ Pros:Compact 1RU form factor for internet edge and private cloud perimeters; 17 Gbps threat prevention throughput (FW+AVC+IPS) at 1024B; 2M concurrent sessions and 3,000 maximum VPN peers; Supports both ASA and Firewall Threat Defense (FTD) software images; 8 x 10G SFP+ ports for high-speed uplinks
✘ Cons:Threat prevention throughput of 17 Gbps is modest for large enterprise or data center deployments; 8 Gbps base IPsec VPN throughput; Subscription licenses for threat defense, URL filtering and malware protection are sold separately and add significant ongoing cost; Cisco's official list price was not found, and retailer prices vary widely by SKU, refurbished status and software image; Some spec figures conflict across reseller pages and should be checked against Cisco's official datasheet
