Comprehensive Product Overview

The FortiGate 100F (FG-100F) is part of Fortinet’s 100F series, built on the Security-Driven Networking framework to unify high-speed network connectivity and advanced enterprise cybersecurity. At its core lies the advanced SPU Security Processor, a purpose-built security chip that offloads compute-intensive tasks like deep packet inspection (DPI), SSL/TLS decryption, and intelligent threat detection—ensuring line-rate performance even under full security service loads.

Key Design & Purpose

• Form Factor: 1U rackmount metal chassis, standard cabinet installation, durable structure for long-term enterprise operation.
• Target Users: Mid-sized enterprises, large branch offices, retail chain groups, campus networks, organizations with 200–400 users.
• Core Mission: Replace legacy enterprise firewalls and scattered security tools with an all-in-one NGFW + SD-WAN solution to reduce deployment complexity and lower long-term TCO.
• FortiOS Integration: Runs on Fortinet’s mature FortiOS, seamlessly compatible with Fortinet Security Fabric including FortiSwitch, FortiAP, FortiManager and FortiAnalyzer.

Unique Value Proposition

Different from low-end entry firewalls with bandwidth limitations, the FG-100F delivers 1Gbps SSL inspection throughput and 20Gbps raw firewall throughput. It stably processes massive encrypted SaaS, cloud platform and conference traffic without latency lag. Its built-in Secure SD-WAN intelligently optimizes multi-link routing, reduces reliance on expensive MPLS lines, and maintains stable transmission of enterprise core business data.
