The 1800F is the first model in the range offering Hyperscale licensing, which lifts concurrent sessions from 12 million to 40 million and new sessions per second from 750,000 to 2 million. It carries four 100GE QSFP28 ports, and FortiOS 7.4 or later is required to use them.
Buy the 1800F for the Hyperscale licence, not the chassis. Without it, the 2600F offers more threat protection (25 vs 15 Gbps) and twice the session count in the same 2 RU. With it, the 1800F handles session volumes that have nothing to do with enterprise inspection, CGNAT, IoT fleets, carrier aggregation.
What to order alongside the FortiGate 1800F
The published threat protection figure for this model is measured with IPS, application control and malware protection all running. Those arrive as a FortiGuard subscription, so the bundle you choose decides whether the hardware can reach the number you sized it on. Every bundle already includes FortiCare Premium 24x7 support.
| Bundle | What it adds | 1 yearlist price | 3 yearslist price | 5 yearslist price |
|---|---|---|---|---|
| Enterprise ProtectionENT | The broadest bundle. Everything in UTP, plus the services that cover data, SaaS posture and attack-surface visibility, plus inline zero-day malware prevention. | $112,953FG-1800F-BDL-809-12 | $207,172FG-1800F-BDL-809-36 | $301,391FG-1800F-BDL-809-60 |

These are Fortinet list prices. You will not pay them.
Every quote we write is discounted from list, and how far below depends on quantity, term and whether we register the deal with Fortinet. Longer terms also price better per year, which is why three and five year bundles are usually the better buy on a device you intend to keep through a refresh cycle. Part numbers follow Fortinet’s standard bundled convention; not every model carries every combination, so we confirm the exact orderable SKU before anything is placed.
FortiGate 1800F is number 5 of 7 in this family
Ranked on threat protection throughput, the figure that separates these models. All values are Fortinet’s own and cited on each product page.
FortiGate 1000F
13 Gbps
15% less than the FortiGate 1800F. Worth it only if your measured requirement genuinely fits inside it.
FortiGate 1800F
15 Gbps
7 models in this family span 2.8 Gbps to 30 Gbps.
FortiGate 700G
26 Gbps
73% more headroom. Worth costing if you expect growth inside the refresh cycle, replacing early is dearer than buying up once.
Highlights

- 4x 100GE QSFP28 (requires FortiOS 7.4+)
- 100,000 firewall policies, 250 VDOMs
- 2x 960 GB storage, DC power variant
Typical deployments
- Carrier-grade NAT and subscriber-facing aggregation
- IoT and telemetry fleets generating enormous session counts
- Environments where the requirement is stated in sessions, not gigabits
The numbers, with their conditions
Every figure below is Fortinet's own, with the test conditions it was measured under.
Performance
Fortinet's published figures. Firewall throughput is measured on UDP with no inspection enabled, size your deployment on threat protection throughput instead, which is measured with firewall, IPS, application control and malware protection all running against an enterprise traffic mix.
| Firewall throughput (1518 / 512 / 64 byte UDP) | 198 / 197 / 140 Gbps |
|---|---|
| IPsec VPN throughput (512 byte)IPsec VPN performance test uses AES256-SHA256. | 55 Gbps |
| IPS throughput (enterprise mix)IPS, application control, NGFW and threat protection are measured with logging enabled. | 22 Gbps |
| NGFW throughput (enterprise mix)NGFW performance is measured with firewall, IPS and application control enabled, enterprise mix traffic. | 17 Gbps |
| Threat protection throughput (enterprise mix)Threat protection performance is measured with firewall, IPS, application control and malware protection enabled, enterprise mix traffic. | 15 Gbps |
| SSL inspection throughput (IPS, avg. HTTPS)SSL inspection performance values use an average of HTTPS sessions of different cipher suites. | 12 Gbps |
| Application control throughput (HTTP 64K) | 34 Gbps |
| Firewall latency | 3.22 µs |
Capacity
| Concurrent sessions | 12 Million / 40 Million |
|---|---|
| New sessions / second | 750,000 / 2 Million |
| Firewall policies | 100,000 |
| Max gateway-to-gateway IPsec tunnels | 20,000 |
| Max client-to-gateway IPsec tunnels | 100,000 |
| SSL VPN throughput | 11 Gbps |
| Concurrent SSL VPN users (recommended max, tunnel mode) | 10,000 |
| Virtual domains (default / max) | 10 / 250 |
Security Fabric capacity
How much of the rest of the Fabric this model manages directly, with no separate controller.
| Max managed FortiAPs (total / tunnel) | 4,096 / 2,048 |
|---|---|
| Max managed FortiSwitches | 196 |
| Max FortiTokens | 20,000 |

Model-specific caveats
Fortinet conditions that apply to this model in particular. Worth reading before you order.

|---|---|
| Note 2 | FortiOS 7.4 or later is required for 100 GE support. |
