2. Complete Detailed Product Overview
Product Line Positioning
The Cisco FPR3120-NGFW-K9 is the mid-high tier modular rack appliance in the Secure Firewall 3100 generation, positioned above entry FPR3110 and below flagship FPR3130/FPR3140. It retains the standard 19-inch 1RU rack form factor and identical base 8×1G copper + 8×1/10G SFP+ native port layout plus one NM-2 expansion bay as the FPR3110, but upgrades to a more powerful unified AMD multi-core security processor and doubles memory to 64GB DDR5 ECC to deliver drastically higher throughput, larger concurrent session capacity and expanded VPN/multi-context limits for large enterprise and nationwide hub workloads.
The modern single-chip unified architecture consolidates firewall forwarding, cryptographic VPN acceleration and full threat inspection workloads on one platform with dedicated hardware QAT offload, eliminating performance degradation when IPS, AVC, TLS decryption and AMP malware defense are fully enabled simultaneously. Factory pre-installed Firewall Threat Defense (FTD) NGFW stack as primary firmware, while retaining native ASA OS compatibility for large-scale legacy ASA hardware migration projects.
The K9 suffix delivers permanent Security Plus unrestricted licensing, removing weak DES encryption limitations and unlocking full enterprise feature set including expanded 75 multi-context virtualization, unlimited TLS proxy sessions, complete dual-mode high availability and 200 VLAN capacity, vastly exceeding discontinued Firepower 2100 legacy appliances. The Secure Firewall 3100 series is Cisco’s current mainstream data center firewall platform with ongoing software updates and full official TAC maintenance support.
