FortiGate 100F: High-Performance Next-Generation Firewall for Modern Enterprises

FortiGate 100F: High-Performance Next-Generation Firewall for Enterprise Networks
Cybersecurity | Network Security | Enterprise IT
As businesses continue to adopt cloud applications, remote connectivity, digital services, and distributed IT infrastructure, securing the network has become a critical priority.
A modern enterprise firewall must do more than control network traffic. It needs to provide advanced threat protection, application visibility, secure connectivity, high performance, and flexible network management.
The FortiGate 100F from Fortinet is designed to address these requirements by combining Next-Generation Firewall (NGFW) capabilities with advanced security features and Secure SD-WAN functionality in a single platform.
What Is FortiGate 100F?
FortiGate 100F is a Next-Generation Firewall (NGFW) designed for enterprise branch offices and mid-sized business environments.
The platform combines network security and SD-WAN capabilities, helping organizations protect their networks while managing connectivity across offices, branches, and distributed environments. Fortinet’s documentation highlights the use of dedicated security processing and SD-WAN acceleration technologies to deliver high performance.
Rather than deploying separate platforms for firewall security, VPN connectivity, and SD-WAN functions, organizations can use FortiGate 100F as a consolidated security and networking platform.
Key FortiGate 100F Performance
Performance is one of the most important considerations when selecting an enterprise firewall.
According to Fortinet’s published specifications, FortiGate 100F provides the following performance levels:
Specification FortiGate 100F
Firewall Throughput Up to 20 Gbps
IPS Throughput Up to 2.6 Gbps
NGFW Throughput Up to 1.6 Gbps
Threat Protection Throughput Up to 1 Gbps
IPsec VPN Throughput Up to 11.5 Gbps
Concurrent TCP Sessions Up to 1.5 million
New TCP Sessions/Second Up to 56,000
Firewall Policies Up to 10,000
These figures are based on Fortinet’s specified testing conditions. Actual performance may vary depending on network traffic, security profiles, inspection features, and deployment architecture.
Advanced Network Security
FortiGate 100F provides multiple security capabilities designed to protect enterprise networks against a wide range of cyber threats.
Key capabilities include:
• Next-Generation Firewall
• Intrusion Prevention System (IPS)
• Application Control
• Antivirus and malware protection
• Web filtering
• SSL Inspection
• IPsec VPN
• Secure SD-WAN
• Security Fabric integration
Fortinet states that FortiGate NGFW platforms are designed to provide visibility and control across applications, users, devices, and network traffic, supported by FortiGuard security services.
This allows organizations to move beyond traditional firewall rules and implement more comprehensive security policies.
Secure SD-WAN for Distributed Networks
Enterprise networks are increasingly distributed across headquarters, branch offices, cloud environments, and remote locations.
This creates challenges for organizations that need to maintain both network performance and security across multiple WAN connections.
FortiGate 100F integrates Secure SD-WAN capabilities to help organizations manage application traffic and WAN connectivity while maintaining security controls.
Fortinet’s FortiGate 100F documentation highlights its dedicated SD-WAN ASIC and application identification and steering capabilities for more than 5,000 applications.
This makes the platform suitable for organizations operating:
• Multiple branch offices
• Multi-site enterprise networks
• Multiple Internet connections
• Hybrid IT environments
• Distributed business operations
• Secure site-to-site VPN architectures
High-Speed Connectivity
Modern enterprise networks require flexible connectivity options for both traditional Ethernet and high-speed uplinks.
The FortiGate 100F provides a combination of:
• GE RJ45 interfaces
• GE SFP interfaces
• 10 GE SFP+ interfaces
• WAN interfaces
• USB
• Console interface
The current Fortinet datasheet specifies 12 GE RJ45 ports, 4 GE SFP ports, and 2 × 10 GE SFP+ FortiLink ports, together with additional shared interfaces and management connectivity.
This interface flexibility allows FortiGate 100F to be integrated into different enterprise network architectures.
SSL Inspection and Application Visibility
Encrypted traffic has become a standard part of modern Internet communication.
While encryption provides important security and privacy benefits, it can also make network traffic more difficult to inspect for potential threats.
FortiGate 100F supports SSL Inspection, allowing organizations to inspect encrypted traffic according to their security policies.
Fortinet publishes up to 1 Gbps SSL Inspection throughput for the FortiGate 100F under its specified testing conditions.
Application Control also provides greater visibility into applications operating across the network, helping administrators create more granular security and access policies.
FortiGate 100F for Enterprise Network Security
FortiGate 100F can be deployed in several enterprise scenarios.
Enterprise Offices
For corporate offices, FortiGate 100F can operate as a network security gateway between internal systems and the Internet.
It can provide firewall protection, application control, threat prevention, VPN connectivity, and other security functions from a single platform.
Branch Offices
For organizations with multiple branches, FortiGate 100F can provide secure connectivity between locations using IPsec VPN and Secure SD-WAN capabilities.
This can help organizations establish consistent security policies across distributed environments.
Multi-Site Networks
Organizations operating multiple offices can use FortiGate as part of a broader network security architecture, helping provide centralized visibility and consistent security controls.
Hybrid IT Environments
As businesses combine on-premises infrastructure with cloud services, secure connectivity between different environments becomes increasingly important.
FortiGate can help organizations manage and protect network traffic across these environments.
Fortinet Security Fabric Integration
FortiGate 100F can operate as part of the broader Fortinet Security Fabric ecosystem.
Fortinet describes Security Fabric as an architecture that enables Fortinet and Fabric-ready technologies to work together for broader visibility, threat intelligence sharing, integrated detection, and automated response capabilities.
For organizations building a larger cybersecurity architecture, this integration can help reduce security silos and provide a more coordinated approach to network protection.
