FortiGate Mid-Range Firewall Performance Comparison
The table below compares FortiGate mid-range firewall models based on threat protection throughput, SSL inspection performance, concurrent session capacity, and overall security capability.
| Model | Threat Protection | SSL Inspection | Concurrent Sessions | Overall Role / Review |
|---|---|---|---|---|
| FortiGate 100F / 101F | 1 Gbps | 1 Gbps | 2,000,000 | Entry-level mid-range NGFW for branch offices and smaller enterprise sites; good balance of security services and affordability with enough capacity for typical WAN and VPN traffic in SMB/branch environments. |
| FortiGate 120G / 121G | Up to 2.8 Gbps (Threat Protection, per G-series guidance) | NGFW throughput 3.1 Gbps | 3,000,000 | New-generation G-series mid-range firewall with SP5 ASIC, designed for higher encrypted traffic visibility and more applications per second than the 100F series, ideal for growing branches needing extra headroom and long lifecycle. |
| FortiGate 200F | 3 Gbps | 4 Gbps | 3,000,000 | Mid-tier appliance for growing networks and campus edges, offering more ports and throughput than the 100F while keeping strong NGFW, IPS, and VPN performance for organizations consolidating multiple security functions on one device. |
| FortiGate 200G / 201G / 201F | 6 Gbps | 7 Gbps | 11,000,000 | High-performance G-series mid-range firewalls aimed at campus and large branch deployments, delivering much higher session scale and SSL inspection than 200F, making them suitable for dense user environments and heavy cloud/SaaS usage. |
| FortiGate 400F | 9 Gbps | 8 Gbps | 7,800,000 | High-capacity mid-range platform for demanding environments, such as midsize data centers and core campus roles, with strong SSL inspection and ample session scale for east-west inspection and segmentation projects. |
| FortiGate 600F / 601F | 10.5 Gbps | 9 Gbps | 7,800,000 – 8,000,000 | Upper mid-range firewall line bridging campus and small data-center use cases, offering higher security compute power, 40G-ready connectivity on some SKUs, and strong price/performance for organizations upgrading from older E-series models. |
| FortiGate 601E | 7 Gbps | 8 Gbps | 8,000,000 | Legacy E-series mid-range firewall that is still referenced for compatible refresh paths; generally recommended to be replaced by newer F- or G-series models to gain better SSL inspection and support life. |
| FortiGate 700G / 701G | 26 Gbps | 14 Gbps | 16,000,000 | Next-generation architecture positioned at the top of the mid-range, providing very high encrypted traffic performance and session scale, suitable for large campuses or internet edges that previously required smaller data-center models. |
| FortiGate 900G | 20 Gbps | 16.7 Gbps | 16,000,000 | Enterprise-class mid-range firewall (borderline data-center tier) offering extremely high SSL inspection and throughput, ideal for organizations with heavy traffic growth, multiple 10/40G uplinks, and a need for long-term scalability. |
| FortiGate 400E Bypass | Hardware bypass model (throughput varies) | Depends on active/inline mode | Varies by deployment | Specialized fail-open inline security appliance commonly used where traffic must continue to pass even on power or appliance failure; typically replaced in new designs by F- or G-series models with integrated bypass options. |
