With 32 built-in interfaces and advanced VPN and SSL inspection capabilities, this appliance balances speed, capacity, and security management in a compact rack-mountable form factor. Key features Firewall throughput up to 52 Gbps to maintain fast network performance even under heavy load Supports up to 11 million concurrent sessions, accommodating complex environments with many users and devices Handles as many as 100,000 firewall policies, allowing fine-grained control over network traffic IPsec VPN throughput of 25 Gbps provides secure, low-latency connections for remote users and satellite sites 4 Gbps SSL inspection throughput detects hidden threats within encrypted traffic Includes 32 built-in interfaces: 16 GbE RJ45 ports for copper connections and 16 GbE SFP ports for fiber links Two 10GbE SFP+ ports enable direct uplinks to high-speed distribution or core switches Redundant and hot-swappable power supplies ensure continuous operation without downtime Pre-installed FortiOS offers a unified console for firewall, intrusion prevention, application control, and VPN management Detailed reporting tools help security teams identify and resolve issues before they impact network availability Key specs Firewall throughput: up to 52 Gbps Concurrent sessions: up to 11 million Firewall policies supported: up to 100,000 IPsec VPN throughput: 25 Gbps SSL inspection throughput: 4 Gbps Interfaces: 16 GbE RJ45 ports, 16 GbE SFP ports, 2 x 10GbE SFP+ ports Form factor: 2U rack-mountable chassis Power supplies: redundant and hot-swappable Connectivity and compatibility The FG-1000D offers a versatile set of network interfaces to fit into a variety of infrastructure setups. The 16 GbE RJ45 ports support standard copper Ethernet connections, while the 16 GbE SFP ports provide fiber connectivity for longer distances or higher noise immunity. The two 10GbE SFP+ ports simplify integration with modern high-speed core or distribution switches, reducing bottlenecks in network uplinks. This range of ports makes the appliance adaptable to diverse network topologies and device types. Performance and reliability Designed for environments where uptime is critical, the FG-1000D includes redundant and hot-swappable power supplies to prevent service interruptions in case of hardware failure. Its ability to handle millions of concurrent sessions and tens of thousands of firewall policies ensures it can support large user bases and complex security requirements without slowing down. The appliance’s SSL inspection capability helps uncover threats hidden in encrypted traffic, maintaining security without compromising performance. Ideal uses and environments This security appliance fits well in mid-sized enterprise headquarters, hosted application environments, and service provider network edges where both speed and security are priorities. It is a strong choice for organizations that require robust firewall protection alongside high throughput and extensive VPN support. The 2U rack-mount design allows it to integrate smoothly into standard data center cabinets, making it suitable for professional IT setups that demand reliable, scalable security solutions.
