Key Features
FPR4112-NGFW-K9 is the Cisco-listed NGFW appliance PID for Firepower 4112, so it should be ordered only when the design requires the Threat Defense NGFW role.
The 4112 tier combines 40 Gbps firewall throughput with 19 Gbps NGFW and 19 Gbps IPS figures, which keeps sizing discussions tied to Cisco’s model table rather than a higher 4115 appliance.
Eight fixed 10G SFP+ data ports provide the base interface set before network modules are selected for additional 1G, 10G, 40G, or 100G connectivity.
The appliance chassis has two module bays, giving firewall projects room for Cisco-approved Firepower 4100 network modules without moving to a different chassis family.
Cisco ordering guidance separates appliance PIDs from Threat Defense security subscriptions, so the BOM should include the required subscription family and term when the deployment needs those services.
The Firepower 4112 hardware plan includes field-replaceable power supply options, hot-swappable fans, SSD, rack hardware, and power cords that should be aligned with the site installation plan.
Application Scenarios
Choose FPR4112-NGFW-K9 for a Cisco Secure Firewall Threat Defense refresh where the approved design uses Firepower 4112 hardware and the base cabling plan starts with 10G SFP+ interfaces.
Use this SKU when procurement records must show the NGFW orderable PID rather than the ASA PID, while keeping the same 4112 chassis class and expansion bay layout.
Deploy the 4112 NGFW appliance when the project needs two network module bays for approved Firepower 4100 I/O expansion but does not require the higher 4115 performance tier.

- In a FPR4112-NGFW-K9 vs FPR4112-ASA-K9 comparison, the confirmed hardware platform is the same 4112 appliance class, but the Cisco PID description separates the NGFW appliance role from the ASA appliance role.
- The FPR4112-NGFW-K9 difference from FPR4115-NGFW-K9 is the model tier: 4112 is listed with 40 Gbps firewall, 19 Gbps NGFW, and 19 Gbps IPS figures, while 4115 is listed with 80 Gbps firewall, 33 Gbps NGFW, and 33 Gbps IPS figures.
- For buyers deciding which model to choose, FPR4112-NGFW-K9 fits a 4112 Threat Defense BOM; FPR4112-ASA-K9 fits an ASA BOM, and FPR4115-NGFW-K9 fits a higher 4115 NGFW sizing target.
Selection Guide
1. Match the NGFW PID to the approved security design
Select FPR4112-NGFW-K9 when the bill of materials requires the Cisco-listed Firepower 4112 NGFW appliance for a Threat Defense deployment.
2. Keep ASA and NGFW orders separated
Use FPR4112-ASA-K9 only when the design and support records require the ASA appliance role; do not substitute it for this NGFW PID without a design change.
3. Size against the 4112 performance row
Confirm that 40 Gbps firewall throughput plus 19 Gbps NGFW and IPS throughput fit the sizing document before staying with the 4112 model.
4. Move to 4115 only for the higher model tier
Compare FPR4115-NGFW-K9 when the same NGFW appliance role is needed but the project requires Cisco’s higher 4115 firewall, NGFW, or IPS figures.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact PID |
FPR4112-NGFW-K9 rather than FPR4112-ASA-K9 or FPR4112-NGIPS-K9 |
Cisco lists separate Firepower 4112 appliance order roles, and the wrong PID changes the software identity in the BOM |
|
Threat Defense software |
Target Secure Firewall Threat Defense release and management plan |
The NGFW appliance should match the software baseline approved for the firewall deployment |
|
Security subscriptions |
Required Threat Defense subscription family and term |
Appliance hardware does not replace subscription entitlement planning for enabled security services |
|
Fixed and modular ports |
Eight fixed 10G SFP+ ports plus any required Firepower 4100 network module |
Interface choices drive optics, cabling, and module ordering |
|
Power and spares |
1100W AC or 950W DC supplies, redundancy, SSD, fans, rack kit, and power cords |
Installation readiness depends on site power and serviceable component planning |
