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

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)
