Fortinet has launched its new FortiGate 3500G and 400G firewalls to strengthen security for AI-driven workloads, encrypted traffic and hybrid enterprise networks, simplifying modern cybersecurity operations.

Fortinet launches new G series firewalls by expanding its FortiGate G series with the launch of FortiGate 3500G and FortiGate 400G firewalls. The new systems are built to secure AI-driven workloads, encrypted traffic, and distributed hybrid environments while maintaining high performance.

 Powered by NP7 and SP5 processors along with FortiOS, the platforms aim to support modern enterprise networks facing rapid digital change across data centers, cloud environments, and edge infrastructure worldwide without compromising operational efficiency or security posture.

Why are enterprises struggling with AI-driven network traffic

Enterprises are facing rising pressure as encrypted traffic, east-west data flows, and AI workloads grow faster than traditional security tools can handle. Many organizations struggle to balance performance with strong protection across distributed systems.

Ken Xie, Fortinet’s founder and CEO, said that modern infrastructure needs security platforms that can scale with AI workloads while keeping operations simple and efficient, ensuring both performance and protection across data centers and enterprise edges. This is pushing companies to rethink how security is built into network architecture from the ground up.

What makes the FortiGate 3500G different for data centers

The FortiGate 3500G is designed for high-performance data centers handling AI workloads and heavy east-west traffic efficiently.

  • 400Gb connectivity for high-speed environments

  • ASIC acceleration improves processing performance at hardware level

  • Built-in validation strengthens trust and system transparency

  • Supports zero-trust models and growing AI workloads without bottlenecks

The platform integrates security directly into infrastructure, helping organizations scale without redesigning networks. It also reduces operational complexity by combining performance and protection in a single system built for modern data centers while improving trust at the hardware level for enterprise adoption globally deployed.

How does the FortiGate 400G modernize the enterprise edge

The FortiGate 400G brings advanced security and performance to enterprise edge networks undergoing rapid modernization.

  • Enables high-density traffic segmentation for complex environments

  • Delivers consistent performance even with advanced security services enabled

  • Offers simplified upgrades for existing FortiGate users

Fortinet says the 400G allows enterprises to modernize edge infrastructure without disruption while keeping policies consistent across distributed systems. It helps IT teams standardize operations and improve visibility across network layers while maintaining predictable performance under heavy load and cloud environments globally.

Where enterprise security is going

As Business Fortune observes, Fortinet is expected to deepen AI-driven security across its firewall portfolio as enterprise networks become more distributed and automated. Future systems will likely focus on predictive threat detection, tighter integration with AI workloads, and self-adjusting security policies that respond in real time to changing network conditions, reducing human intervention and improving resilience across global enterprises in coming years.
