The 3800G delivers 200 Gbps of threat protection, 250 Gbps of IPS and 315 Gbps of application control in 3 RU with four power supplies. It carries four 400GE, six 200GE QSFP56 and eighteen 50GE SFP56 ports, and reaches 450 million sessions with Hyperscale.
The top of the fixed-appliance range for inspected throughput, and the point at which a chassis becomes the only step up. It nearly doubles the 3500G's threat protection and is the only fixed FortiGate with 200GE QSFP56 attachment.
What to order alongside the FortiGate 3800G
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. | $842,546FG-3800G-BDL-809-12 | $1,538,696FG-3800G-BDL-809-36 | $2,234,846FG-3800G-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 3800G is the top 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 3500G
105 Gbps
90% less than the FortiGate 3800G. Worth it only if your measured requirement genuinely fits inside it.
FortiGate 3800G
200 Gbps
11 models in this family span 25 Gbps to 200 Gbps.
Top of the family
Nothing larger in this line. Beyond this the design changes, clustering, a different product, or a conversation rather than a bigger box.
Highlights
- 200 Gbps threat protection, 250 Gbps IPS
- 4x 400GE and 6x 200GE QSFP56, unique in the fixed range
- Hyperscale: 450M sessions, 7M new sessions/sec
- 400,000 firewall policies, 4 power supplies
Typical deployments
- Large data-centre perimeter with full inspection at 200 Gbps
- 200GE fabric attachment without a chassis
- Consolidating several older high-end firewalls into one pair
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) | 795 / 793 / 453 Gbps |
|---|---|
| IPsec VPN throughput (512 byte)IPsec VPN performance test uses AES256-SHA256. | 210 Gbps |
| IPS throughput (enterprise mix)IPS, application control, NGFW and threat protection are measured with logging enabled. | 250 Gbps |
| NGFW throughput (enterprise mix)NGFW performance is measured with firewall, IPS and application control enabled, enterprise mix traffic. | 210 Gbps |
| Threat protection throughput (enterprise mix)Threat protection performance is measured with firewall, IPS, application control and malware protection enabled, enterprise mix traffic. | 200 Gbps |
| SSL inspection throughput (IPS, avg. HTTPS)SSL inspection performance values use an average of HTTPS sessions of different cipher suites. | 120 Gbps |
| Application control throughput (HTTP 64K) | 315 Gbps |
| Firewall latency | 3.53 µs |
Capacity
| Concurrent sessions | 210 Million / 450 Million |
|---|---|
| New sessions / second | 1.1 Million / 7 Million |
| Firewall policies | 400,000 |
| Max gateway-to-gateway IPsec tunnels | 40,000 |
| Max client-to-gateway IPsec tunnels | 200,000 |
| SSL VPN throughput | 27 Gbps |
| Concurrent SSL VPN users (recommended max, tunnel mode) | 30,000 |
| Virtual domains (default / max) | 10 / 500 |
Security Fabric capacity
How much of the rest of the Fabric this model manages directly, with no separate controller.
| Max managed FortiAPs (total / tunnel) | 8,192 / 4,096 |
|---|---|
| Max managed FortiSwitches | 300 |
| Max FortiTokens | 20,000 |
