Max Sessions: Not published in the sources reviewed
New Sessions/sec: Not published in the sources reviewed
Interfaces: 1x 2.5GbE RJ45 WAN, 4x GbE RJ45 LAN (one LAN port can be reconfigured as a second WAN for multi-WAN)
Form Factor: Compact desktop; UCG-Max-NS variant includes 512GB NVMe storage
Curation Review
✔ Pros:Low entry price at $199 MSRP; Compact desktop form factor; Five-port layout with multi-WAN support via a reconfigurable LAN port; Runs UniFi OS with integrated IDS/IPS, site-to-site and remote VPN options (IPsec, WireGuard, OpenVPN, L2TP); Manages 30+ UniFi devices and 300+ clients per Ubiquiti listing
✘ Cons:Routing and IPS throughput (2.3 Gbps) is modest for multi-gigabit WANs with inspection enabled; Published throughput figures conflict across sources (1.5 vs 2.3 Gbps IPS, varying VPN numbers); Only one 2.5GbE port, with the remaining ports at 1GbE; Vendor does not publish IPsec tunnel, session, or new-connection limits; Some resellers list prices well above MSRP (one US listing at $394.79)

Curation Review
✔ Pros:Built-in UniFi controller, so no separate Cloud Key needed; Low price for a gateway with IDS/IPS and controller included; Built-in IDS/IPS with no subscription fee; 2.5GbE WAN port for multi-gig internet; Multi-WAN failover or load balancing; Low power draw and fanless design; VPN (IPsec, OpenVPN, WireGuard) and VLANs without a subscription
✘ Cons:IDS/IPS ceiling of 1 Gbps limits secure throughput on links above about 1 Gbps; Real-world throughput drops further with PPPoE or threat detection enabled; No Wi-Fi radio, so separate access points are required; No PoE output and no UniFi Protect, Access, or Talk support; Only one 2.5GbE port; the other four are 1GbE; Runs warm and should not be stacked on heat-generating equipment; Firewall and VPN throughput figures are not published by Ubiquiti, so buyers must rely on third-party tests
