Fortinet today announced new additions to its FortiGate G series portfolio, designed to help organizations secure and scale modern enterprise networks. The FortiGate 3500G and FortiGate 400G deliver high-performance security that keeps pace with growing encrypted traffic, AI-driven workloads, and distributed environments, enabling organizations to strengthen protection, maintain performance, and simplify operations across hybrid infrastructures.
Fortinet expands FortiGate G series with 3500G (data center) and 400G (enterprise edge) models.
Powered by NP7 and SP5 processors with FortiOS operating system for ASIC-accelerated performance.
Native shadow AI detection provides real-time visibility into unsanctioned AI application usage.
FortiGate 3500G delivers 400Gb connectivity with hardware-level validation and secure firmware enforcement.
FortiOS 8.0 expands visibility through MCP and agent-to-agent traffic inspection for AI data flows.
FortiGuard AI-Powered Security Services apply continuously updated threat intelligence and machine learning.
“Organizations modernizing their infrastructures for AI-driven workloads and increasingly distributed environments need security platforms that can deliver both performance and protection at scale,” said Ken Xie, Founder, Chairman of the Board, and Chief Executive Officer at Fortinet. “The expansion of our FortiGate G series reflects our commitment to helping customers simplify their architectures, reduce complexity, and protect their AI deployments from the data center to the enterprise edge.”
With encrypted traffic, east-west data flows, and AI-driven threats accelerating, traditional firewall architectures are reaching their limits, forcing organizations to choose between performance and security. The FortiGate G series eliminates that trade-off with a unified platform built on Fortinet's custom ASIC acceleration, delivering predictable, high-performance security, integrated threat intelligence, and consistent operations across hybrid environments.
FortiGate 3500G and 400G extend Fortinet's AI-driven Security Fabric with native shadow AI detection, providing real-time visibility into unsanctioned usage across AI applications while enforcing controls to protect sensitive data. FortiGuard AI-Powered Security Services apply continuously updated intelligence and machine learning to identify and prioritize threats and automate protection, with FortiOS 8.0 expanding visibility through MCP and agent-to-agent traffic inspection for deeper control over AI data flows and access.
The FortiGate 3500G series is built for the next era of data center scale and performance, where AI workloads, east-west traffic growth, and zero-trust requirements are redefining how infrastructure operates. Security is no longer a checkpoint—it is foundational to performance, scale, and trust.
Designed for this shift, the 3500G delivers 400Gb connectivity, advanced ASIC acceleration, and significant performance gains to secure high-density environments without introducing bottlenecks or requiring architectural redesign. It also addresses a growing gap in the market: trust in the security infrastructure itself. With hardware-level validation, secure firmware enforcement, and system-level transparency, the platform enables organizations to move from assumed trust to verified trust.
By tightly integrating security enforcement with SOC operations and maintaining familiar form factors, the FortiGate 3500G enables organizations to scale critical infrastructure, simplify operations, and deploy high-performance security with confidence.
Extending these capabilities to the enterprise edge, the FortiGate 400G series modernizes the mid-range firewall segment by bringing G-series performance, architecture, and operational consistency to distributed environments.
As applications span data centers, cloud, and edge, and encrypted and east-west traffic continue to surge, many legacy firewalls struggle to maintain performance when advanced security services are enabled, creating trade-offs between protection and efficiency. The FortiGate 400G eliminates compromises with consistent, hardware-accelerated performance, integrated threat intelligence, and a platform designed to support high-density traffic and segmentation-driven security without added complexity.
