Robust firewall is not just an IT asset but a fundamental component of business security, especially for Small and Medium-sized Businesses (SMBs). Fortinet’s FortiGate firewalls are a leading choice, offering a potent combination of security and performance. This article delves into a comparison of three popular entry-level to mid-range models often considered by SMBs: the FortiGate 40F, 60F, and 80F. We’ll also touch upon the emerging “G” series to keep you informed of the latest advancements.

While you might have heard about a “G” series (e.g., FortiGate 30G, 50G, 120G), for the direct 40, 60, and 80 model range, the “F” series (40F, 60F, 80F) remains the most established and widely available lineup for SMBs. The “G” series generally introduces newer hardware, such as advanced Security Processing Units (SPUs) like the FortiSP5, promising enhanced performance and efficiency. However, direct “40G, 60G, or 80G” counterparts to the F-series aren’t as clearly delineated in the SMB market segment at this time. Specific models like the “FortiGate 40F-3G4G” exist, indicating an F-series unit with integrated cellular capabilities, rather than a base “40G” model.

Therefore, our primary focus will be on the well-documented and widely deployed 40F, 60F, and 80F models, which offer a strong foundation for SMB network security.

Key Considerations for SMBs:

Before diving into the specifics, SMBs should consider these factors when choosing a firewall:

• Number of Users: How many employees and guests will be connecting to the network?
• Internet Speed: What is your current and anticipated internet bandwidth? The firewall shouldn’t become a bottleneck.
• Security Services: Do you need basic firewalling, or advanced features like Intrusion Prevention (IPS), Antivirus (AV), Web Filtering, Application Control, and SSL Inspection? Enabling these features (often part of a Unified Threat Management or UTM bundle) impacts performance.
• VPN Requirements: Will you need secure connections for remote employees (SSL VPN) or site-to-site VPNs to connect multiple offices?
• Network Interfaces: How many wired connections (Ethernet ports) do you need? Do you require specific port types like SFP for fiber connectivity or PoE (Power over Ethernet) for devices like access points or IP phones?
• Future Growth: Choose a model that can accommodate your anticipated growth in terms of users and traffic for the next few years.
• Management & SD-WAN: FortiGates are known for their FortiOS operating system, which provides a comprehensive management interface and robust SD-WAN (Software-Defined Wide Area Network) capabilities, even in entry-level models. This allows for optimized and resilient connectivity across multiple internet links.

FortiGate F-Series for SMBs: 40F, 60F, 80F

These models are all desktop form-factor firewalls, often fanless, making them suitable for small office environments. They are powered by Fortinet’s System-on-a-Chip (SoC) processors, which accelerate security and networking functions.

• FortiGate 40F: Typically positioned for very small businesses, retail locations, or home offices. It’s a cost-effective entry point into the FortiGate ecosystem, offering solid security for networks with a smaller number of users and moderate internet speeds. Some variants, like the 40F-3G4G, include built-in cellular modems for WAN redundancy or primary connectivity.
• FortiGate 60F: A very popular model for small to medium-sized businesses. It offers a significant step up in performance and port density compared to the 40F. It’s often considered the workhorse for SMBs needing robust threat protection without breaking the bank.
• FortiGate 80F: Aimed at medium-sized businesses or larger branch offices that require higher throughput, more concurrent sessions, and greater interface flexibility, including SFP ports on some variants. It can handle faster internet connections and a larger number of users engaging in more demanding network activities.

In-Depth Comparison Table: FortiGate 40F, 60F, 80F

Below is a table comparing key specifications. Note that exact figures can vary slightly based on FortiOS versions and specific testing methodologies. “Threat Protection Throughput” is a crucial metric as it reflects performance with common security services enabled.

Note: Some specifications like “Threat Protection Throughput” are measured with multiple security services active and represent a more realistic performance expectation. Always refer to the latest official datasheets from Fortinet for the most up-to-date information as specifications can change.

Key Differences and Use Cases Summarized:

• FortiGate 40F: Best for very small offices (e.g., <10-20 users) with basic internet speeds and standard security needs. Its lower throughput for threat protection means it’s suited for environments where intensive security scanning isn’t constantly maxed out. The 40F-3G4G variant is excellent for locations needing cellular failover.
• FortiGate 60F: The sweet spot for many SMBs (e.g., 20-75 users). It provides a good balance of performance, port count, and price. It can handle faster internet connections and a more comprehensive set of security services running concurrently without significant performance degradation for its target user base.
• FortiGate 80F: Suitable for larger SMBs (e.g., 75-150+ users), branch offices with heavier traffic, or businesses with higher performance demands due to specific applications or faster internet links (e.g., gigabit). The availability of SFP ports on some models offers flexibility for fiber optic connections. Higher concurrent session and new sessions/second capacity make it better suited for busier networks.

The Emerging “G” Series and What It Means for SMBs

While this article focuses on the F-series, it’s worth noting Fortinet’s ongoing G-series rollout. Models like the FortiGate 50G and 120G showcase the next generation, often featuring:

• Newer Security Processors (SPUs): For instance, the FortiSP5 found in some G-series models offers significant performance improvements in firewalling, VPN, and threat protection throughput, as well as better power efficiency.
• Enhanced AI/ML Capabilities: Leveraging AI for more advanced threat detection and response.
• Support for Newer Technologies: Such as 5G, Wi-Fi 6/6E (in WiFi-enabled models).

For SMBs, this means that as G-series models become more prevalent in the 40-80 replacement range, you can expect even better performance and more advanced security features. If you are purchasing now, the F-series offers proven, robust security. If your purchase horizon is further out, or if specific G-series models in your required size become available, they will likely offer a performance edge.

Important Note on Licensing and Subscriptions:

FortiGate firewalls require FortiGuard security service subscriptions for features like AV, IPS, web filtering, antispam, and FortiSandbox Cloud. These are typically bundled (e.g., UTP – Unified Threat Protection bundle). Factor these ongoing costs into your total cost of ownership. FortiCare support provides hardware replacement, firmware updates, and technical assistance.

Conclusion: Making the Right Choice

Choosing the right FortiGate model involves a careful assessment of your current needs and future growth plans.

• For very small businesses or budget-conscious setups with basic needs, the FortiGate 40F is a solid starting point.
• For most small to medium-sized businesses requiring a balance of performance, features, and cost, the FortiGate 60F is often the ideal choice.
• For larger SMBs, those with faster internet, or more demanding security/connectivity needs, the FortiGate 80F provides the necessary headroom and interface options.

Always consult with a trusted IT partner or Fortinet reseller to discuss your specific requirements and get the latest recommendations. By understanding the capabilities of these FortiGate models, SMBs can make an informed decision to secure their networks effectively against the ever-evolving threat landscape.
