Cisco Firepower 4110 (FPR4110-NGFW-K9): Specs, Data Filtering & Market Share

Jun 21 , 2025 1152

TL;DR: The Cisco Firepower 4110 (FPR4110-NGFW-K9) is a 1U, rack-mount next-generation firewall from Cisco's Firepower 4100 series, delivering up to 35 Gbps of stateful firewall throughput and deep packet inspection for network data filtering. It combines the Firepower Threat Defense (FTD) software with hardware acceleration for application control, URL filtering, and encrypted-traffic inspection. Cisco ranks #3 in the global firewall appliance market (behind Palo Alto Networks at 28.4% and Fortinet), per Omdia 2024 Q4 data. Used and pre-owned Firepower 4110 units offer the same hardware at a fraction of list price — read on for full specs, pricing, and comparison with the FPR4120.

What Is the Cisco Firepower 4110?

The Firepower 4110 is the entry model of Cisco's Firepower 4100 series, positioned between the Firepower 2100 line and the carrier-grade 9300 chassis. It runs the same Firepower Threat Defense (FTD) image as the rest of the family, which means it supports full next-generation firewall features: stateful inspection, intrusion prevention (Snort 3), application visibility and control (AVC), URL filtering, and TLS/SSL decryption. For data-center edge and campus core deployments that need multi-gigabit inspection without the price tag of a 4140 or 4150, the 4110 is a proven, widely deployed choice.

Because the 4110 and the entire 4100 series share the same software image, licensing model (NGFW, ASA, or Threat Defense), and management ecosystem (Firepower Management Center, FMC), many enterprises standardize on the series and scale up or down by chassis — which is exactly why the used market for these appliances stays liquid.

Cisco Firepower 4110 Key Specifications

Below are the hardware specifications for the FPR4110 chassis (source: published spec sheets and the Cisco Firepower 4100 hardware documentation).

Performance context: Cisco's current 4100-series successor model, the FPR4112, is rated at 40 Gbps stateful firewall throughput (ASA image) and 19 Gbps FTD throughput (FW + AVC + IPS at 1024B) with up to 10 million concurrent sessions and 98K new connections per second — a useful reference point for sizing a used 4110 in modern traffic environments.

Firepower 4110 Network Data Filtering Explained

"Network data filtering" is the term buyers use when they search for what the Firepower 4110 can actually inspect and block in line. Here is what the FPR4110-NGFW-K9 does at full inspection:

• Application filtering (AVC): identifies and controls over 4,000 applications by fingerprint, not just by port — shadow-IT apps, peer-to-peer, and high-risk services can be blocked or rate-limited while business apps pass.
• Intrusion prevention (Snort 3): the Firepower 4100 series offloads IPS inspection to dedicated hardware, so the 4110 runs the Snort-based IPS engine with minimal throughput loss compared to general-purpose CPU architectures.
• URL filtering: category-based web filtering (malware, phishing, adult, gambling, social media) with per-user policies via integration with Active Directory.
• TLS/SSL decryption: re-encrypts and inspects HTTPS traffic, which is where most modern malware and data exfiltration hide.
• File and malware inspection: AMP (Advanced Malware Protection) inline file blocking and retrospective analysis with file trajectory.
• Data-aware filtering: security intelligence feeds (Talos) block known bad IPs, domains, and URLs in real time — Talos is the largest commercial threat-intelligence team in the industry.

For a used-hardware buyer, the key point is that all of the above ships with the FPR4110-NGFW-K9 software bundle — the inspection capability is not degraded on a used unit, it is identical to a new one. What differs is only the residual support entitlement, which LinkNewNet can help you source (SNTC, SMARTnet, or third-party maintenance).

Firepower 4110 vs Firepower 4120

The FPR4120 is the next step up in the series: a 2U chassis with roughly double the throughput headroom (up to 55 Gbps stateful firewall throughput) and higher session capacity, aimed at core/aggregation segments where the 4110's single-digit-Gbps inspection envelope is not enough.

Rule of thumb: if you are protecting a single site with up to ~10 Gbps of traffic and need multi-gigabit IPS inspection, the 4110 fits. If you are aggregating multiple sites, doing heavy SSL inspection, or expecting traffic to double within three years, step up to the 4120. Both share the same FMC management and the same FTD software, so migrating between them is a config export away.

Firepower 4110 Market Share and Revenue Context

Why does this matter for buyers? Because the vendor's market position determines software longevity, threat-feed quality, and resale value. Cisco is the #3 firewall appliance vendor worldwide: according to Omdia's 2024 Q4 cybersecurity market report, Palo Alto Networks holds the #1 position with a 28.4% share (first since 2021), followed by Fortinet at #2, Cisco at #3, and Check Point rounding out the top four — all four holding double-digit shares over the past five years. The broader network-security market grew 5.1% year over year in Q4 2024 (3.1% for the full year), and the firewall segment is forecast to grow at a ~5.0% CAGR through 2029.

For the Firepower 4100 line specifically, Cisco has continued to invest: the 4112/4115/4125/4145 refresh released in the early 2020s proves the 4100 hardware platform is still Cisco's mid-range security appliance workhorse, with new chassis outliving the original 4110/4120 models. That longevity is exactly what makes the used Firepower 4110 a low-risk purchase: the platform is not end-of-sale, parts and spares remain available, and FTD software updates continue to be released for the series.

Used & Pre-Owned Firepower 4110 Pricing and Availability

A new FPR4110-NGFW-K9 lists in the five-figure range with subscriptions priced separately. On the used and pre-owned market, the same hardware typically sells at roughly 70-90% below original list price depending on condition (grade A pre-owned vs. pulled-from-production), included licenses, and remaining support. Typical configurations to source:

• FPR4110 chassis + NGFW (Threat Defense) license — the standard bundle for a new deployment
• FPR4110 with FPR4K-NM-4X40GE or NM-8X10GE network modules for higher-density sites
• FPR4110 with spare PSUs, rail kits, and 10 GE optics (SFP+/QSFP+) from our accessories catalog
• Renewed SMARTnet/SNTC coverage or third-party maintenance to protect the investment

Can I upgrade a used Firepower 4110 to the latest FTD version?

Yes. FTD upgrades are delivered as software images; the 4110 supports the current FTD releases available for the 4100 series. Confirm the exact maintenance release with your vendor, as some newer images require prior upgrade paths.

What power does the Firepower 4110 need?

The 4110 takes dual hot-swappable 1100W AC or 950W DC power supplies (100-240 V AC, 50/60 Hz), supporting full redundancy in a single 1U slot.

How much does a used Cisco Firepower 4110 cost?

Used/pre-owned Firepower 4110 appliances typically sell at 70-90% below original list price; final pricing depends on condition, software licenses, and support coverage. Request a quote from LinkNewNet for current stock and pricing.

Conclusion

The Cisco Firepower 4110 (FPR4110-NGFW-K9) remains one of the most sensible mid-range NGFW buys on the used market: a 1U, dual-PSU chassis with multi-gigabit inspection, full data filtering features, an active software roadmap, and a vendor sitting #3 in a market worth tens of billions — with the #4 position hot on its heels and a 5% CAGR tailwind. Whether you are filtering traffic for a campus edge, a data-center segment, or a regional office, the 4110 does the job at a used price that makes new-firewall budgeting look like overkill.
