IPsec VPN Throughput: 22.4 Gbps (1024B TCP with fastpath); projected 39.4 Gbps with VPN offload on FTD 7.2
Max Sessions: 10 million concurrent (with AVC)
New Sessions/sec: 300,000 (with AVC, Cisco datasheet; some resellers cite 1.1 million)
Interfaces: 8 x 1/10/25G SFP Ethernet, 8 x 10M/100M/1G RJ-45 Ethernet, 1 x 1/10G SFP management, 1 x RJ-45 console, 1 x USB 3.0; 4 x 40G network module options; up to 24 total Ethernet ports
Form Factor: 1RU rack-mount (1.75 x 17 x 20 in), dual 400W AC PSUs standard with 1+1 redundancy
Curation Review
✔ Pros:Strong 45 Gbps firewall and threat prevention throughput in a 1RU chassis; 8 x 25G SFP ports for high-speed uplinks and server connectivity; 10 million concurrent sessions suits large enterprise and data-center edges; Clustering support of up to 8 chassis for scale-out and high availability; Dual redundant power supplies (1+1) improve uptime; Runs either FTD (Threat Defense) or ASA software, with a 20,000 VPN peer capacity; VPN offload on FTD 7.2 projects roughly 39.4 Gbps IPsec throughput
✘ Cons:High acquisition cost; reseller prices range widely, roughly $40k to $115k+ before subscriptions; Threat prevention and IPS licenses are sold separately and add significant recurring cost; Throughput figures use 1024B test packets and ideal conditions, so real-world results with mixed traffic and full inspection will be lower; The 1.1M vs 300K new-connections-per-second figures conflict across sources, so sizing requires verification; Software-dependent feature set (FTD vs ASA SKUs have different part numbers and capabilities); No PoE or built-in Wi-Fi, so it cannot serve as a switch or access point; 1RU form factor with 25 lb weight and 400W PSUs needs rack space and adequate power and cooling
