The 3200F is the lowest-cost route to 400GE optics in the FortiGate range, carrying four 400GE QSFP-DD and twelve 50GE SFP56 ports. It delivers 45 Gbps threat protection and 29 Gbps SSL inspection with 70 million concurrent sessions in 2 RU.
Chosen for its optics rather than its inspection performance. If your spine is 400GE and you need a firewall that can attach to it directly without breakout cables, this is the entry point. On pure inspected throughput the 3000G outperforms it substantially — so if 400GE is not a requirement, look there first.
Highlights
- 4x 400GE QSFP-DD — the range's cheapest 400GE attachment
- 12x 50GE SFP56 for spine and leaf uplinks
- 45 Gbps threat protection, 109 Gbps application control
- 70 million concurrent sessions
Typical deployments
- 400GE spine attachment without breakout optics
- Modern data-centre fabrics standardised on QSFP-DD
- High-bandwidth segmentation between fabric zones
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) | 387 / 385 / 178.5 Gbps |
|---|---|
| IPsec VPN throughput (512 byte)IPsec VPN performance test uses AES256-SHA256. | 105 Gbps |
| IPS throughput (enterprise mix)IPS, application control, NGFW and threat protection are measured with logging enabled. | 63 Gbps |
| NGFW throughput (enterprise mix)NGFW performance is measured with firewall, IPS and application control enabled, enterprise mix traffic. | 47 Gbps |
| Threat protection throughput (enterprise mix)Threat protection performance is measured with firewall, IPS, application control and malware protection enabled, enterprise mix traffic. | 45 Gbps |
| SSL inspection throughput (IPS, avg. HTTPS)SSL inspection performance values use an average of HTTPS sessions of different cipher suites. | 29 Gbps |
| Application control throughput (HTTP 64K) | 109 Gbps |
| Firewall latency | 3.42 µs |
Capacity
| Concurrent sessions | 70 Million |
|---|---|

| 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) | 4,096 / 2,048 |
|---|---|
