FPR4145-NGFW-K9 Description
FPR4145-NGFW-K9 is a Cisco Firepower 4145 NGFW firewall appliance in the Cisco Secure Firewall 4100 Series, built for Threat Defense firewall and security-services deployments at the data center or high-capacity network edge. Cisco identifies this exact PID as a 1RU Firepower 4145 NGFW appliance with two network module bays, eight fixed 1/10G SFP+ data ports, 384 GB memory, 800 GB storage, and dual 1100W AC power supplies; the Cisco 4100 Series performance table places the 4145 Threat Defense profile at 53 Gbps for FW + AVC + IPS throughput and 55 Gbps for NGIPS throughput.

Product Performance
Key Features
Cisco lists FPR4145-NGFW-K9 as the Firepower 4145 NGFW appliance, so procurement should not substitute the ASA or NGIPS orderable identity when Threat Defense is required.
The 4145 Threat Defense row raises NGFW summary performance to 53G, IPS summary performance to 55G, and new connection scale with AVC to 365K.
Cisco’s Firepower 4100 hardware table assigns the 4145 model 384 GB memory and 800 GB storage, giving it the largest memory profile in the 4112, 4115, 4125, and 4145 group.
The appliance has eight fixed 1/10G SFP+ data ports and two network module bays for Cisco-listed 1G, 10G, 40G, 100G, or hardware-bypass expansion options.
Cisco notes that the 2-port 100G network module is first supported in Threat Defense 7.3.1 and ASA 9.18.1, so the software plan matters when 100G expansion is part of the order.
For Threat Defense deployments, Cisco documents centralized management through Management Center or Cisco Defense Orchestrator, Active/Standby HA, and clustering up to 16 appliances or instances.
Application Scenarios
Use FPR4145-NGFW-K9 when the firewall refresh standard names a Firepower 4145 NGFW appliance and the approved sizing table requires the 53 Gbps Threat Defense performance row.
Select this SKU instead of FPR4125-NGFW-K9 when the design keeps 1RU Firepower 4100 hardware but needs the 4145 memory, NGIPS, AVC session, and new-connection entries.
Choose the 4145 NGFW appliance for deployments that begin with eight fixed SFP+ ports and need two Cisco-confirmed module bays for high-speed or hardware-bypass interface choices.

- In a FPR4145-NGFW-K9 vs FPR4125-NGFW-K9 comparison, both are 1RU NGFW appliances with 800 GB storage and dual 1100W AC power, while FPR4145-NGFW-K9 adds 384 GB memory, 53G NGFW summary performance, 55G IPS summary performance, and 365K new connections per second with AVC.
- The FPR4145-NGFW-K9 difference from FPR4115-NGFW-K9 is broader than one throughput row: the 4145 also moves to 800 GB storage, 384 GB memory, 30 million AVC sessions, 24 Gbps IPsec VPN throughput, and dual 1100W AC power.
- For buyers comparing FPR4145-NGFW-K9 vs FPR4125-NGFW-K9, the 4145 should be ordered only when the sizing worksheet requires the larger 4145 Threat Defense performance and memory profile.
- In a FPR4145-NGFW-K9 vs FPR4115-NGFW-K9 comparison, which model to choose depends on whether the project can stay at the 4115 NGFW scale or needs the 4145 NGFW appliance row.
Selection Guide
1. Preserve the Threat Defense order identity
Choose FPR4145-NGFW-K9 when the approved design names the Firepower 4145 NGFW appliance and not the ASA or NGIPS version of the same 4145 platform.
2. Use the 4145 row only when sizing requires it
Keep this SKU for projects that need 53 Gbps FW + AVC + IPS throughput, 55 Gbps NGIPS throughput, 30 million AVC sessions, or 365K new connections per second with AVC.
3. Step down only with a confirmed lower scale target
Move to FPR4125-NGFW-K9 or FPR4115-NGFW-K9 only if the capacity plan accepts the lower memory, session, new-connection, VPN, or storage entries shown in the Cisco tables.
4. Bind modules, optics, and software before ordering
Verify Threat Defense, FXOS, fixed-port optics, 40G or 100G module plans, power cords, SSD spares, and fan spares before commercial review begins.
Ordering Checklist
|
Review Area |
Required Decision |
Source-Based Risk |
|---|---|---|
|
Appliance identity |
Use FPR4145-NGFW-K9 when the design requires the 4145 Threat Defense appliance |
The 4145 family has separate NGFW, ASA, and NGIPS PIDs that should not be treated as interchangeable |
|
Software baseline |
Pair the selected Threat Defense release with the correct FXOS release for Firepower 4145 |
Unsupported release combinations can block deployment even when the hardware PID is correct |
|
100G module support |
Add FPR4K-NM-2X100G only after confirming the Threat Defense version requirement |
Cisco marks the 100G network module with first-support release guidance |
|
Expansion bay plan |
Select the needed 1G, 10G, 40G, 100G, or hardware-bypass network modules |
The two module bays define the interface count and whether fail-to-wire behavior is available |
|
Power installation |
Match dual 1100W AC supplies with the correct regional power cords |
Rack installation depends on the power-module and cord standard ordered with the appliance |
