FortiGate 90G — Powerful NGFW for Growing Businesses

For Hong Kong businesses that have outgrown entry-level firewalls, the FortiGate 90G delivers the next step up in performance, security, and scalability. Part of Fortinet’s G-series NGFW lineup, the 90G is designed for larger branch offices and small headquarters that need enterprise-grade protection without enterprise-level complexity.

FortiGate 90G at a Glance

The 90G sits above the 70G in Fortinet’s G-series, offering substantially higher throughput and port density. It is powered by Fortinet’s custom FortiASIC SP5 processor, delivering hardware-accelerated performance even with full security features enabled.

• Firewall throughput: 28 Gbps
• NGFW throughput: 2.5 Gbps
• IPsec VPN throughput: 25 Gbps
• Concurrent sessions: 3 million
• Users: Up to 200
• Form factor: Desktop, low-noise design

Key Features

High Port Density

The 90G includes 8 x GE RJ45 ports plus 2 x shared-media WAN ports supporting either 10 GbE RJ45 or 10 GbE SFP+. This flexibility allows Hong Kong businesses to connect multiple internal networks and high-speed WAN links without additional switching hardware. Some models also include PoE support, simplifying deployment for VoIP phones and wireless access points.

Advanced SD-WAN

Built-in SD-WAN capabilities enable intelligent traffic steering across multiple WAN connections, ensuring critical applications like video conferencing and cloud ERP perform reliably. Combined with FortiGate’s zero-touch deployment (BLE-enabled), setting up branch offices becomes significantly faster.

Consolidated Security

The 90G integrates next-generation firewall (NGFW), IPS, SSL inspection, application control, and antivirus into a single platform. With 2.2 Gbps threat protection throughput, you can run all security features enabled without sacrificing performance — ideal for the increasing threat landscape facing Hong Kong businesses.

Comparison: 70G vs 90G

If you are evaluating which G-series model fits your needs, the 90G offers roughly double the firewall throughput of the 70G and significantly higher VPN capacity. It is best suited for organisations with 100–200 users, multiple branch locations, or requirements for 10 GbE connectivity.

• Simplified management — managed via FortiCloud or FortiManager alongside your existing FortiGate fleet

For existing FortiGate users, remember that keeping your FortiGate license renewed is essential to maintain protection against the latest threats.

Is FortiGate 90G Right for Your Business?

The 90G is ideal for Hong Kong SMEs that have outgrown entry-level models (such as the 50G or 60F) and need higher throughput, more ports, and advanced SD-WAN capabilities. It is also an excellent choice as a consolidated branch platform, replacing multiple standalone appliances with a single FortiGate unit.
