Fortinet FortiGate FG-90G Network Security/Firewall Appliance

The Fortinet FortiGate FG-90G Network Security/Firewall Appliance is a compact, high-performance NGFW designed to protect small to mid-sized networks with enterprise-grade security. Engineered to deliver advanced threat protection while simplifying deployment and ongoing management, the FG-90G combines robust firewall capabilities with integrated SD-WAN, secure VPN connectivity, and a resilient security fabric. This makes it an ideal choice for branch offices, retail locations, and distributed enterprises seeking a reliable, scalable, and easy-to-manage security appliance that can adapt to growing network demands without sacrificing performance.

• Comprehensive next-generation firewall and threat protection: The FG-90G goes beyond traditional packet filtering by delivering deep inspection across traffic flows, including IPS (intrusion prevention), application control, SSL/TLS inspection, antivirus, and web filtering. This ensures that known and unknown threats are detected and neutralized before they can compromise networks, endpoints, or data. The integrated security features are designed to protect against evolving attack vectors while maintaining smooth user experiences, making it ideal for environments where security cannot be compromised.
• Integrated SD-WAN for reliable, cost-efficient connectivity: Embedding SD-WAN capabilities directly into the firewall appliance simplifies branch connectivity. The FG-90G intelligently selects the best path for traffic across multiple WAN links, improves application performance, and enhances availability. This reduces dependency on a single ISP, lowers transport costs, and helps ensure consistent performance for cloud-based applications, voice, video, and critical business workflows even during WAN disruptions.
• FortiOS and security fabric integration for centralized control: Running FortiOS, the FG-90G is part of the Fortinet Security Fabric. This integration provides cohesive security across the network, with centralized visibility, logging, and policy management. Administrators can leverage FortiManager and FortiAnalyzer for scalable management, advanced analytics, and consistent policy enforcement across multiple devices, branches, and data centers. The result is streamlined operations, faster threat detection, and unified reporting across the network.
• Branch-friendly form factor with flexible deployment options: The FG-90G is designed to fit small office and remote site environments without requiring substantial space or infrastructure. Its compact form factor, rich set of interfaces, and easy setup enable quick deployment to protect edge networks. The appliance supports straightforward firmware updates, security service subscriptions, and scalable licensing so as your network grows, protection remains strong without complexity.
• Secure connectivity and versatile VPN capabilities: To support remote access and site-to-site connectivity, the FG-90G provides robust VPN features, including IPsec and SSL VPN capabilities. This ensures secure, encrypted communications for remote employees, partner networks, and branch-to-branch connections. VPNs are designed to be reliable, easy to configure, and maintainable, enabling secure access while preserving performance for critical applications and data flows.
