The Cisco Firepower 2140 (FPR2140-ASA-K9) is the flagship model of the Firepower 2100 Series, delivering 12 Gbps of FTD throughput and 15.4 Gbps of NGIPS performance — the most powerful fixed-chassis appliance in the 2100 family. It is designed for the most demanding enterprise internet edges, large data centre perimeters, and high-throughput service provider gateways.

With 6 million concurrent sessions and 4 × 10G SFP+ ports, the FPR2140 can handle the full bandwidth of a 10G ISP connection with all NGFW inspection features enabled, while maintaining a session table large enough to accommodate enterprise-scale traffic without drops. Its 3.5 Gbps of TLS decryption throughput means even the most encrypted traffic environments receive full visibility.

The FPR2140 includes a Network Interface Module (NIM) expansion slot — allowing future interface additions (e.g., 40G QSFP or additional 10G SFP+ ports) to keep pace with bandwidth growth. Running ASA software, the FPR2140 delivers 24 Gbps of stateful inspection — the highest in the 2100 Series — with active/active HA clustering for maximum utilisation.

For organisations investing in the Cisco Secure Firewall platform, the FPR2140 provides the compute headroom to run Encrypted Traffic Analytics (ETA), which identifies malware in TLS traffic without full decryption — preserving privacy while closing the encrypted traffic blind spot that many competing approaches cannot address at this throughput level.
