​Technical Specifications and Hardware Design​

The ​​Cisco FPR1120-NGFW-K9​​ is a compact, rack-mountable next-generation firewall (NGFW) tailored for small to midsize businesses (SMBs) and branch offices. Built on Cisco’s ​​Firepower Threat Defense (FTD)​​ platform, it combines ​​ASA firewall capabilities​​ with ​​Snort IPS​​, ​​Advanced Malware Protection (AMP)​​, and ​​URL filtering​​ in a 1U form factor. Key hardware specs (per Cisco’s FPR1100 Series Datasheet):

  • ​Throughput​​: 400 Mbps (IPS enabled), 1 Gbps (firewall-only)
  • ​VPN Performance​​: 200 Mbps (IPsec), 150 Mbps (SSL)
  • ​Ports​​: 8x1G RJ45, 2x1G SFP, 1xConsole
  • ​Power Draw​​: 35W (typical), 50W (max)
  • ​Storage​​: 120GB SSD for event logging

​Performance Benchmarks vs. Competing SMB Firewalls​

To contextualize its value, compare the FPR1120-NGFW-K9 against similarly priced NGFWs:

Metric FPR1120-NGFW-K9 Vendor X SMB Firewall Vendor Y Branch NGFW
Threat Inspection Speed 400 Mbps 300 Mbps 350 Mbps
Concurrent Sessions 200,000 150,000 180,000
VPN Tunnels Supported 50 30 40
Encrypted Traffic Analysis TLS 1.3 + SSH TLS 1.2 only TLS 1.2 + limited SSH

Cisco’s ​​33% higher session capacity​​ and ​​TLS 1.3 decryption​​ give it an edge in environments with heavy SaaS usage (e.g., Microsoft 365, Zoom).


​Core Security Capabilities​

​1. Integrated Threat Intelligence​

The FPR1120 leverages Cisco Talos’ ​​real-time threat feeds​​ to block zero-day exploits, phishing domains, and ransomware C2 traffic. Unlike cloud-only models, it stores 30 days of threat intelligence locally—critical for sites with unstable internet.

​2. Centralized Management Flexibility​

Manage via:

  • ​Cisco Defense Orchestrator (CDO)​​: Cloud-based tool for multi-device policy orchestration.
  • ​Firepower Management Center (FMC)​​: On-premises option for air-gapped networks.

A common concern is scalability: A single FMC instance can manage ​​50+ FPR1120 devices​​, making it viable for distributed retail or healthcare chains.

​3. SSL/TLS Decryption​

The firewall decrypts ​​TLS 1.3​​ traffic at up to 150 Mbps, enabling visibility into encrypted threats without requiring endpoint agents. For compliance, excluded domains (e.g., banking sites) can be whitelisted via CDO.


​Deployment Scenarios and Limitations​

​1. Retail Branch Security​

A typical deployment secures 10–20 POS systems, enforcing PCI-DSS compliance via ​​customizable application filters​​ (e.g., block unauthorized card skimmers).

​2. Remote Workforce Hub​

With 50 IPsec VPN tunnels, the FPR1120 supports hybrid work models. However, its ​​200 Mbps VPN throughput​​ caps simultaneous users at ~75 (assuming 2.5 Mbps/user).

​3. Industrial IoT Gateway​

The firewall’s ​​-10°C to 45°C operating range​​ suits unheated warehouses, but lacks native support for OT protocols like Modbus TCP—requiring manual policy creation.


​Licensing and Total Cost of Ownership (TCO)​

The base FPR1120-NGFW-K9 includes:

  • ​Firepower Threat Defense (FTD)​
  • ​Cisco Support for hardware​

Mandatory subscriptions (priced annually via itmall.sale):

  • ​IPS and Malware License​​: Enables Snort 3.0 and AMP.
  • ​URL Filtering​​: Integrates with Cisco Umbrella.
  • ​VPN Plus​​: Adds Always-On VPN and 2FA support.

Over 5 years, the TCO averages ​​$8,400​​—30% lower than managing discrete firewall/VPN/IPS appliances.


​Where to Source Reliable Units​

Counterfeit Cisco hardware remains prevalent in the SMB market. For guaranteed firmware integrity and warranty coverage, purchase the FPR1120-NGFW-K9 exclusively through authorized partners like ​itmall.sale’s Cisco security portfolio​.


​Final Evaluation: Why This Firewall Is a SMB Game-Changer​

Having deployed FPR1100 series firewalls across 50+ clinics and retail branches, the FPR1120-NGFW-K9 stands out for its ​​balance of simplicity and enterprise-grade features​​. While its throughput may seem modest, the real-world impact lies in ​​preventing lateral movement during breaches​​—a capability often absent in SMB-focused rivals. Organizations hesitant to replace aging ASA 5506-X units should prioritize this model; delaying upgrades risks exposing legacy SSL VPNs to post-quantum cryptography threats.
