Fortinet introduces two new FortiGate Next-Generation Firewalls

Fortinet has introduced two new G series FortiGate Next-Generation Firewalls, the FortiGate 3500G and FortiGate 400G.

Both products are powered by Fortinet’s NP7 and SP5 processors running the FortiOS operating system, with the new series combining advanced threat protection, integrated intelligence and hardware-enforced security.

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 3500G delivers 400Gb connectivity, advanced ASIC acceleration and performance gains, alongside hardware-level validation, secure firmware enforcement, and system-level transparency.

The FortiGate 400G series brings G-series performance, architecture, and operational consistency to distributed environments, wlong with hardware-accelerated performance, integrated threat intelligence, and a platform designed to support high-density traffic and segmentation-driven security without added complexity.

With a simplified upgrade path from existing FortiGate deployments and consistent interfaces across the portfolio, the 400G enables organisations to modernise their network edge, standardise operations and scale security with predictable performance and minimal disruption, the company claims.

“Organisations modernising 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 centre to the enterprise edge.”
