Firewall Throughput: Not published by Ubiquiti in the sources reviewed
Threat Prevention Throughput: 2.3 Gbps IDS/IPS per Ubiquiti spec page (older listings show 1.5 Gbps)
IPsec VPN Throughput: Not published by Ubiquiti; third-party reviews report about 800-1,000 Mbps for WireGuard and 300-400 Mbps for OpenVPN
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)
Max Sessions: 1.5 million concurrent connections (with AVC)
New Sessions/sec: 90,000 new connections per second with AVC (FTD); 150,000 new connections per second (ASA)
Interfaces: 8 x 10M/100M/1GBASE-T RJ-45 + 8 x 1/10G SFP+ fixed (16 ports); up to 24 total Ethernet ports with 8 x 1/10G network module option; 1 x 1/10G SFP management port
Form Factor: 1RU rack-mount appliance (1.75 x 17 x 20 in), single 400W AC PSU (dual optional), AC or DC input
Max VPN Peers: 2,000
Clustering: Not supported on 3105
Layer: L3 firewall (Layer 3 security appliance; no PoE)
Curation Review
✔ Pros:Delivers 10 Gbps firewall and threat prevention throughput in a compact 1RU form factor; Supports FTD and ASA software images, giving a choice of NGFW or classic ASA feature sets; Provides 1.5 million concurrent connections and up to 2,000 VPN peers for a small appliance; Offers 16 fixed ports (8 copper, 8 SFP+) with optional 8-port 1/10G expansion module; Dual power supply option improves availability; Carries a comparatively low price point within the Secure Firewall 3100 series
✘ Cons:No clustering support, so no horizontal scale-out or HA cluster beyond standard failover; IPsec VPN throughput of 5.5 Gbps is well below the 10 Gbps firewall rating; Stateful and threat prevention throughput are both capped at 10 Gbps, limiting use in high-throughput data centers; Optional 10G expansion and dual PSU raise the total cost well above base pricing; Reseller prices vary widely and no official Cisco list price is published on the datasheet; Requires Cisco Secure Firewall subscription licenses (threat, malware, URL) for full feature use, which are priced separately
