The 50G is the most configurable model in the entry-level range, shipping in WiFi, DSL, SFP, PoE and 5G variants. It delivers 1.1 Gbps threat protection and 1.3 Gbps SSL inspection — the latter more than four times the 40F it supersedes — on five gigabit ports with 64 GB of local storage.
The right default for a modern branch where the uplink type varies by site. If some locations are fibre, some DSL and some cellular, standardising on the 50G family means one model, one spares pool and one configuration template across the whole estate. Its 85,000 new sessions per second is more than double the 40F's, which matters for chatty applications.
Highlights
- 1.1 Gbps threat protection, 1.3 Gbps SSL inspection
- Five variants: WiFi, DSL, SFP, PoE and 5G
- 85,000 new sessions/sec — 2.4x the 40F
- 64 GB local storage for on-box logging
Typical deployments
- Multi-site branch estates with mixed uplink types
- Sites needing PoE for a couple of phones or cameras without a separate switch
- DSL-served locations where an integrated modem removes a device
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) | 5 / 5 / 4 Gbps |
|---|---|
| IPsec VPN throughput (512 byte)IPsec VPN performance test uses AES256-SHA256. | 4.5 Gbps |
| IPS throughput (enterprise mix)IPS, application control, NGFW and threat protection are measured with logging enabled. | 2.25 Gbps |
| NGFW throughput (enterprise mix)NGFW performance is measured with firewall, IPS and application control enabled, enterprise mix traffic. | 1.25 Gbps |
| Threat protection throughput (enterprise mix)Threat protection performance is measured with firewall, IPS, application control and malware protection enabled, enterprise mix traffic. | 1.1 Gbps |
| SSL inspection throughput (IPS, avg. HTTPS)SSL inspection performance values use an average of HTTPS sessions of different cipher suites. | 1.3 Gbps |
| Application control throughput (HTTP 64K) | 2.8 Gbps |
| Firewall latency | 2.42 µs |
Capacity
| Concurrent sessions | 720,000 |
|---|---|
| New sessions / second | 85,000 |
| Firewall policies | 2,000 |
| Max gateway-to-gateway IPsec tunnels | 200 |
| Max client-to-gateway IPsec tunnels | 250 |
| SSL VPN throughput | — |
| Concurrent SSL VPN users (recommended max, tunnel mode) | — |
| Virtual domains (default / max) | 5 / 5 |
Security Fabric capacity
How much of the rest of the Fabric this model manages directly, with no separate controller.
| Max managed FortiAPs (total / tunnel) | 16 / 8 |
|---|---|
| Max managed FortiSwitches | 8 |
| Max FortiTokens | 500 |
Hardware
| Interfaces | 5x GE RJ45 |
|---|---|
| Local storage | 64 GB (51G) |
| Power supplies | Single AC PS |
| Form factor | Desktop |
| Variants | WiFi, DSL, SFP, PoE, 5G |
