FPR4112-NGFW-K9 Description

The FPR4112-NGFW-K9 is a Cisco Secure Firewall 4100 Series Firepower 4112 NGFW appliance for internet-edge and data center perimeters that run Threat Defense. The 1RU appliance delivers 19 Gbps of FW + AVC + IPS throughput, 10 million concurrent sessions and 4.5 Gbps of hardware TLS decryption, with eight fixed 1G/10G SFP+ ports and two network module bays. Threat Defense high availability is active/standby, and clustering reaches 16 appliances.

Key Features

Inspection Throughput

Threat Defense passes 19 Gbps with FW + AVC and the same 19 Gbps with FW + AVC + IPS (1024B). NGIPS throughput is also 19 Gbps, so enabling IPS does not lower the rated figure.

Hardware TLS Decryption

Decryption runs in hardware at 4.5 Gbps, measured with 50% TLS 1.2 AES256-SHA and RSA 2048 traffic. Encrypted flows can be inspected without moving the work onto the main CPUs.

Session And VPN Scale

The appliance holds 10 million concurrent sessions and sets up 98,000 new connections per second with AVC. IPsec VPN reaches 8.5 Gbps for up to 10,000 peers.

Multi-Instance And Clustering

Multi-Instance runs separate Threat Defense instances on one chassis, and clusters scale to 16 appliances or 16 instances. Standalone high availability is active/standby.

Fixed Ports And Module Bays

Eight fixed SFP+ ports run at 1G or 10G. The two bays take 8x10G, 4x40G or 2x100G modules, up to 24 10G ports or four 100G ports in total.

Power And Cooling

Two 1+1 power slots hold 1100W AC or 950W DC supplies, and the unit ships with one AC supply. Six hot-swappable fans cool the chassis front to rear.

Application Scenarios

Internet Edge With IPS

At an enterprise internet edge, the appliance applies application visibility and IPS to traffic at 19 Gbps, with 4.5 Gbps of that inspection able to look inside TLS sessions in hardware.

Data Center North-South Inspection

A data center border can place the appliance between the core and the upstream routers, using the fixed SFP+ ports at 10G and the module bays for 40G uplinks.

Multi-Instance Security Segments

An organization that separates business units or compliance zones can run several Threat Defense instances on one chassis, or cluster up to 16 appliances as capacity grows.

FPR4112-NGFW-K9 runs Threat Defense on the same 1RU chassis as FPR4112-ASA-K9 and is rated at 19 Gbps with application inspection and IPS, where the ASA appliance is rated at 40 Gbps of stateful inspection, so the choice follows the software rather than the hardware. Sites that must stay on Cisco ASA, with up to 250 security contexts and active/active failover, should order FPR4112-ASA-K9. Where Threat Defense must pass 19 Gbps, FPR4115-NGFW-K9 lists 33 Gbps of NGFW and IPS throughput on 192 GB of memory instead of 96 GB, with the same 400 GB SSD and single 1100W AC supply by default.

Ordering Checklist

  • Threat subscription: Order one of L-FPR4112T-T=, -TC=, -TM=, -TMC=, -AMP= or -URL=, plus the term suffix -1Y, -3Y or -5Y, such as L-FPR4112T-TMC-3Y. Threat (T) is the prerequisite for Malware and URL Filtering, and the 5-year term carries the largest discount.
  • Smart Software Licensing account: Set up an account for the end customer, or link the existing account to the order. The account is required before the order is placed, so the licenses have nowhere to be deposited otherwise.
  • Bundle or single PID: Choose FPR4112-BUN for the master bundle, FPR4112-FTD-HA-BUN for a two-unit HA pair, or the single FPR4112-NGFW-K9. The bundle PID is advised unless there is a specific reason, because it brings every required component on one order.
  • Network modules: Decide which of FPR4K-NM-8X10G, FPR4K-NM-4X40G or FPR4K-NM-2X100G goes in the two bays; FPR4K-NM-2X100G needs Threat Defense 7.3.1 or later. The bays ship empty of modules beyond the eight fixed SFP+ ports, and an unsupported release cannot use the 100G module.
  • Power supplies: The unit ships with one FPR4K-PWR-AC-1100; add a second one, or choose FPR4K-PWR-DC-950 where the site feeds DC. The second slot is 1+1 redundancy; DC and blank-panel choices are separate PIDs.
  • Power cords: Order one cord per supply in the destination country’s standard; orders to Argentina, Brazil and Japan must include the matching cord. Those destinations cannot be shipped without the cord ordered on the system.
