IPsec VPN Throughput: 140 Gbps (per Cisco 4200 series listing)
Max Sessions: 60 million concurrent (with AVC, per Cisco datasheet)
New Sessions/sec: 800,000 (unverified; one listing cites 1.7M)
Interfaces: 8 x 10GbE SFP+ on-chassis; 2 NetMod bays supporting up to 8 x 25GbE SFP28 (netmod-dependent)
Form Factor: 1U rackmount
Curation Review
✔ Pros:Very high throughput for a 1U appliance (140 Gbps threat prevention and IPsec VPN, per Cisco datasheet); 60 million concurrent sessions with AVC for large data center and campus edge deployments; Modular NetMod bays allow 25GbE SFP28 connectivity; Supports Cisco Firepower Threat Defense (FTD) or ASA software images; Multi-instance support for consolidating workloads; Strong integration with Cisco Firepower Management Center and Cisco security ecosystem
✘ Cons:Very high acquisition cost compared with mid-range NGFWs; Throughput and session figures vary across Cisco and reseller sources, so validation against the current datasheet is needed; Max VPN peer count and new connections per second are not confirmed by an authoritative Cisco source; Full 25GbE capacity requires purchasing separate NetMod modules; Licensing (threat, malware, URL) is a significant recurring cost on top of hardware
