FirewallSecure Firewall 3100 Series
Mid-range threat-focused firewalls that make hybrid work and zero trust practical.
Cisco Secure Firewall 3100 Series is a family of mid-range, threat-focused appliances delivering business resiliency and superior threat defence from the Internet edge to the data centre and private cloud. A modern CPU and purpose-built hardware keep performance high even with advanced threat functions enabled, and clustering scales as you grow. Five models span 10–49 Gbps. Faltrox deploys, tunes, and manages it.
Overview
What Secure Firewall 3100 Series is
The Secure Firewall 3100 Series is Cisco’s mid-range firewall, built to make hybrid work and zero trust practical with strong return on investment. Its five models deliver firewall throughput from 10 Gbps to 49 Gbps, addressing use cases from the Internet edge to the data centre and private cloud, and it supports clustering to scale performance as the organisation grows.
Purpose-built hardware optimises firewall, cryptographic, and threat-inspection functions so advanced protection — Snort 3 IPS, application control, URL filtering, malware defence, and the Encrypted Visibility Engine — stays fast under load. Each model runs ASA or Firewall Threat Defense and can operate in firewall or dedicated IPS mode, managed by Firewall Management Center or cloud Security Cloud Control and integrated with Cisco XDR and Talos. Faltrox deploys it, designs the policy and clustering, and operates it as managed defence.

How it works
The mechanism
How the product moves from signal to protected state, step by step.
- 01
Size
Choose from five models (3105–3140) for 10–49 Gbps, sized to the Internet edge, data centre, or private cloud.
- 02
Deploy
Run ASA or FTD in firewall or dedicated IPS mode, onboarded to Firewall Management Center or cloud Security Cloud Control.
- 03
Inspect
Purpose-built hardware runs firewall, crypto, and threat inspection — IPS, AVC, URL, malware — at high throughput.
- 04
Scale
Add appliances to a cluster to increase performance as demand grows, without redesigning the perimeter.
- 05
Operate
Faltrox designs the policy and clustering, maintains software, and monitors the firewalls as managed defence.
Capabilities
Key capabilities
Purpose-Built Hardware
A modern CPU with dedicated crypto and threat-inspection hardware sustains performance with advanced functions on.
Snort 3 IPS
Next-generation intrusion prevention, deployable in firewall or dedicated IPS mode.
Application & URL Control
Application visibility and control plus category and reputation URL filtering.
Encrypted Visibility Engine
Detects threats in encrypted traffic without the performance cost of full decryption.
Clustering
Scale performance by clustering multiple appliances as the organisation grows.
FTD or ASA
Run Firewall Threat Defense or ASA software for a consistent operating model across the estate.
Cisco XDR & Talos
Detections are enriched by Cisco Talos intelligence and correlated across the environment via Cisco XDR.
Flexible Management
Manage via on-premises Firewall Management Center or cloud-delivered Security Cloud Control.
Works with
Part of the platform
Cisco products this pairs with, and the Faltrox services that operate it.
Delivery
You buy the outcome, not the console
Managed by Faltrox
Faltrox licenses, deploys, and tunes Cisco Secure Firewall 3100 Series for your environment, then runs it as part of a managed service, so you get the protection without staffing another security console.
FAQ
Common questions
01What use cases does the 3100 Series cover?
Its five models (10–49 Gbps) span the Internet edge to the data centre and private cloud, making it Cisco’s mid-range firewall for organisations that need strong threat defence with headroom to grow via clustering. Faltrox sizes the model to your throughput and use case.
02How does it stay fast with threat functions enabled?
Purpose-built hardware optimises firewall, cryptographic, and threat-inspection functions separately, so advanced protection like IPS and malware defence runs without the throughput collapse that hits general-purpose firewalls under full inspection.
03Can it grow with us?
Yes — the 3100 Series supports clustering, so you add appliances to increase performance as your needs grow rather than replacing the platform, protecting the initial investment.
04Can it run as a dedicated IPS?
Yes. Each model can be deployed in firewall mode or dedicated IPS mode, and supports inline sets and passive interfaces — so it can serve as a next-generation firewall or a standalone IPS as your architecture requires.
05How does Faltrox operate it?
We deploy and size the appliances, design the policy, clustering, and segmentation, maintain software, and monitor the firewalls — integrating their detections into the SOC services we run for managed defence.
