New Sessions/sec: 170,000 (FTD, with AVC); 500,000 (ASA)
Interfaces: 8x 1GBASE-T RJ-45 + 8x 1/10G SFP+ (integrated); up to 24 total Ethernet ports with network modules; 1x 1/10G SFP management port; max 7,000 VPN peers
Form Factor: 1RU rack-mount; 1.75 x 17 x 20 in; single 400W AC PSU (dual optional)
Curation Review
✔ Pros:Up to 22 Gbps stateful firewall throughput in a compact 1RU chassis; 4 million concurrent sessions and 170,000 new connections/sec for high-density traffic; Supports both ASA and FTD (Threat Defense) software images for deployment flexibility; Integrated 8x 1GbE copper and 8x 10G SFP+ ports with expansion modules for up to 24 ports; Hardware VPN offload raises IPsec throughput to 13.5-15.4 Gbps and supports up to 7,000 VPN peers; Redundant power supply option available
✘ Cons:Only about 21 Gbps threat-prevention throughput, which is modest for full inspection on high-speed links; IPsec VPN throughput without offload is only 10 Gbps; Limited to 10G maximum port speed with no 25G/40G/100G options; Pricing is high relative to newer-generation platforms, and no official Cisco list price is published; Cisco has announced end-of-sale timelines for the 3100 series, so buyers should check lifecycle status before purchase; Ports are not PoE and the device has no built-in Wi-Fi or switching features
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
