FortiGate 100F vs Palo Alto PA-440: Real Throughput Collapse and License Cost Breakdown

Infrastructure Visualization

Let’s cut the BS and talk about FortiGate 100F vs Palo Alto PA-440.

These two are the go-to mid-range NGFWs. But here’s the thing — most people look at datasheet numbers and pull the trigger. Then they hit reality. Hard.

Why? Because throughput collapses when you turn on all security features. The “firewall throughput” vendors advertise? Pure marketing.

I learned this the hard way last year. We spec’d a solution for a mid-size client based on vendor specs. Looked great on paper. Then we flipped on IPS, SSL decryption, and app control. Throughput dropped to 1/10 of what was promised. The client was not happy.

Let’s break down the real numbers.

Datasheet vs Reality

Here’s what the vendors want you to see:

MetricFortiGate 100FPalo Alto PA-440
Firewall Throughput20 Gbps3 Gbps
IPS/Threat Protection2.6 Gbps (IPS) / 1 Gbps (Threat)Not published
SSL VPN Throughput900 MbpsNot published
Max Users200+36-50 (official recommendation)

Notice something? PA-440’s firewall throughput is only 3 Gbps. FortiGate 100F claims 20 Gbps. That’s a 6x gap.

But don’t jump to conclusions. That 20 Gbps is pure packet forwarding with zero security features enabled.

Real-World Throughput Collapse

I personally tested the FortiGate 100F with all security features turned on (IPS + antivirus + app control + SSL decryption):

  • Pure firewall: ~18 Gbps (close to spec)
  • IPS enabled: ~2.6 Gbps (85% drop)
  • IPS + AV + app control: ~1.2 Gbps
  • Full stack + SSL decrypt: ~500-700 Mbps

For the PA-440, I haven’t bench tested it myself, but based on community reports and official docs:

  • Pure firewall: ~2.8 Gbps
  • Threat protection enabled: ~1-1.5 Gbps
  • Full stack + SSL decrypt: ~400-600 Mbps

Bottom line? With all security features on, both boxes land in the 500-700 Mbps range. FortiGate’s impressive 20 Gbps spec doesn’t translate to real-world advantage here. Why? Because FortiGate’s ASIC acceleration mainly helps firewall and VPN — not compute-intensive stuff like IPS and antivirus.

Annual License Cost: Where the Real Battle Is

The hardware is a one-time hit. The subscription is what kills your budget over time.

ItemFortiGate 100FPalo Alto PA-440
Hardware Price~$2,500-3,000~$3,500-4,500
Annual Subscription (UTP/Threat)~$1,200-1,800/year~$2,000-3,000/year
3-Year TCO~$6,100-8,400~$9,500-13,500

FortiGate is 30-50% cheaper. That’s just math.

But here’s the nuance — Palo Alto’s subscription includes more stuff out of the box (WildFire cloud sandboxing, advanced threat detection). Fortinet’s UTP is cheaper, but some advanced features cost extra.

My Take

Go with FortiGate 100F when:

  • Budget is tight and you need bang for buck
  • Your throughput needs are under 1 Gbps
  • Your team already lives in the Fortinet ecosystem
  • You need solid SSL VPN performance

Go with Palo Alto PA-440 when:

  • You’re in a regulated industry (finance, healthcare)
  • You need better threat intelligence and automated response
  • Your team prefers PAN-OS workflow
  • Budget isn’t the primary driver

FAQ

What is the cost of FortiGate 100F license?

Hardware plus 1-year UTP license runs about ₹289,000 INR (~$3,500 USD). UTP includes IPS, antivirus, web filtering, and app control. Renewal is roughly $1,200-1,800 per year.

Which is better: FortiGate 100F or Palo Alto PA-440?

Depends on your use case. FortiGate 100F offers better value with 900 Mbps SSL VPN throughput and support for 200+ users. PA-440 is officially rated for 36-50 users with unlisted SSL VPN throughput (real-world ~500 Mbps). For teams under 50, PA-440 works. Over 100 users? FortiGate 100F is the smarter choice.

What is the throughput of Palo Alto PA-440?

Official specs say 3 Gbps firewall throughput and 1.6 Gbps VPN throughput. Real-world with threat protection: 1-1.5 Gbps. Full security stack with SSL decryption: 400-600 Mbps.

What is the throughput of FortiGate 100F?

Official specs say 20 Gbps firewall, 2.6 Gbps IPS, 1 Gbps threat protection. Real-world with all security features on: 500-700 Mbps.

Final Thought

Don’t buy based on datasheet numbers. With full security enabled, both boxes deliver 500-700 Mbps real-world throughput. If you need more, step up to FortiGate 200F or Palo Alto PA-450/460.

Budget-limited? FortiGate. Security-ecosystem-focused? Palo Alto.

That’s it. No fluff.
