Fortinet FortiGate 70G

Overview

The Fortinet FG-70G is a next-generation firewall appliance designed for branch offices, distributed sites and small to mid-sized enterprise deployments. Built on Fortinet’s unified operating system and ASIC-accelerated architecture, it merges networking and security functions in a compact form factor. The appliance supports SD-WAN, zero trust access, deep inspection and a full suite of threat-protection services, enabling organisations to reduce complexity while maintaining high performance and robust protection. Whether you’re securing wired or wireless edges, remote sites or multi-cloud connectivity, the FG-70G delivers enterprise-grade security with manageable cost, footprint and power consumption.

Features

• Converged firewall plus SD-WAN: Integrates next-generation firewall (NGFW) capabilities with SD-WAN in a single appliance, simplifying branch-site deployments.
• Unified operating system: Runs Fortinet’s FortiOS, enabling a consistent operating model for networking and security functions across your environment.
• ASIC acceleration: Hardware-accelerated processing ensures high throughput with low latency, while reducing power consumption and cost compared to legacy CPU-based devices.
• High performance threat inspection: Supports intrusion prevention, application control, web filtering, SSL/TLS inspection and advanced malware protection, enabling deep visibility and control of encrypted traffic.
• Zero Trust Network Access (ZTNA) & secure remote connectivity: Enables secure access for users and devices from anywhere, integrating into the security fabric and supporting VPN, policy enforcement and segmentation.
• Branch-friendly form factor: Compact desktop design with fanless or low-noise operation (depending on variant) makes it suitable for small offices, retail or distributed environments.
• Expandable, manageable: Supports centralised management (via FortiManager or FortiGate Cloud), integrates with Fortinet switch and wireless access-point ecosystems (FortiSwitch, FortiAP), and includes SD-WAN orchestration, link-balancing and path optimisation.
• Energy efficient & future-ready: Designed to deliver industry-leading throughput per watt, enabling minimal environmental impact while preparing for evolving threat landscapes and network growth.
