Comprehensive Product Overview
The FortiGate 81F (FG-81F) is the top-performing model in Fortinet’s 80F series, built for mid-sized businesses and branch networks requiring high-speed security and SD-WAN capabilities in a compact form factor. As a fanless desktop appliance, it operates silently (0 dBA) with low power consumption (max 16.5W), making it ideal for office environments, retail locations, and remote sites where noise and heat are concerns.
Engineered with Fortinet’s proprietary SoC4 (System-on-Chip 4), the FG-81F combines network acceleration (NP6) and content processing (CP9) into a single chip, delivering industry-leading performance without compromising security. It supports 1.5 million concurrent TCP sessions and 45,000 new sessions per second, ensuring reliable connectivity for up to 200 users. The 128GB SSD provides ample local storage for logs, reports, and configurations, eliminating the need for external storage in most deployments.
As a unified security platform, the FG-81F integrates NGFW, secure SD-WAN, IPS, antivirus, web filtering, application control, and SSL VPN into one device, simplifying network architecture and reducing operational complexity. It is certified by ICSA Labs for firewall, IPsec, IPS, antivirus, and SSL-VPN, ensuring compliance with enterprise security standards.
