Max Sessions: 90 Million concurrent firewall connections (ASA table; older datasheet revision lists 80 Million)
New Sessions/sec: 1.7 Million (ASA stateful firewall)
Interfaces: 2 x NetMod bays for expansion modules; reseller listing shows 8 x SFP+ on-chassis
Form Factor: 1RU rack-mount, dual power supply, 80 Plus Platinum
Curation Review
✔ Pros:Strong 80 Gbps threat prevention and IPsec VPN throughput in a 1RU chassis; Two NetMod bays allow interface expansion without replacing the appliance; Available as ASA or Threat Defense (NGFW) software images, so the same hardware can serve different deployment needs; Supports high concurrent session counts (up to 90 million) and 1.7 million new connections per second for busy data center or campus edge use; Cisco Firepower Management Center and Cisco Defense Orchestrator give centralized management and policy control
✘ Cons:High upfront cost, with reseller prices typically from about $145K to over $200K before subscriptions; Threat Defense features require ongoing subscription licensing, which adds recurring cost; Published throughput and session figures differ across Cisco datasheet versions and resellers, so specs must be verified against the current datasheet before purchase; Overkill for small and mid-sized businesses that need far less throughput; Requires NetMod modules and separate optics, which add to total cost of ownership
✔ Pros:25G SFP28 and 10G SFP+ uplinks at a gateway price point; 23.5 Gbps routing throughput; 1 million concurrent sessions; 18-core ARM CPU with 16 GB RAM; hot-swappable redundant PSUs; supports 500+ UniFi devices and 5,000+ clients; manages through UniFi Network controller with a single pane of glass
✘ Cons:IPsec VPN throughput of 580 Mbps is low for a gateway at this price; IDS/IPS throughput of 12.5 Gbps halves routing performance when threat inspection is enabled; SSL/TLS inspection is limited to about 10,000 concurrent sessions; port configuration differs across listings and should be verified; frequently out of stock at major US retailers, with a $170 memory surcharge at some resellers; no built-in Wi-Fi, so it depends on separate UniFi APs and switches; reviewers cite a steeper learning curve than consumer-grade routers
