Product Overview

The FortiGate 3700F is a 2U, rack-mount next-generation firewall delivering industry-leading throughput, massive session capacity and high-speed connectivity, built for very large enterprises, cloud operators, service providers and data-centre backbones. It combines ultra-high firewall and VPN performance, hardware-accelerated inspection, and a full FortiOS security stack — positioning it as a core security gateway for high-volume, latency-sensitive, encrypted and mixed traffic environments.

Ideal deployment / environment
FG-3700F is optimally placed at the network core, data-centre perimeter or WAN backbone, where traffic volumes are high, encrypted and mixed, and performance must not be compromised. It secures high-capacity internet uplinks, inter-data-centre links, cloud ingress/egress, VPN backbones and backbone routing — all while applying full NGFW, IPS, SSL/HTTPS inspection, application control and threat protection.

Broad interface support and throughput capability make FG-3700F suited to large enterprises, service providers, multi-tenant data centres, and cloud-scale environments that require both raw performance and comprehensive security. The 3700F allows consolidation of firewalls, VPN gateways, SSL inspection, DDoS protection and traffic inspection into a single platform — simplifying infrastructure and delivering long-term scalability and resilience.

Key Features​

  • Firewall throughput up to 589 Gbps (IPv4/IPv6, UDP) and packet-forwarding capacity up to 630 Mpps.
  • Up to 160 Gbps IPsec VPN
  • Support for 40,000 gateway-to-gateway tunnels and 200,000 client VPN tunnels.
  • IPS up to 86 Gbps
  • Threat-protection throughput up to 75 Gbps
  • SSL-inspection up to 55 Gbps (HTTPS traffic) even under heavy load.
  • Hardware-accelerated ports supporting 400 GE QSFP-DD, 200 GE QSFP56, 100 GE QSFP28, 50 GE SFP56, 25 GE SFP28, 10 GE SFP+, plus GE RJ45 — ideal for backbone, data-centre interconnect and multi-tier backbone deployments.
  • Up to 140 million concurrent TCP sessions, 930,000 new sessions per second
  • Support for 200,000 firewall policies.

Documentation

Q1. How does Fortinet support zero trust and segmentation at scale?

Fortinet Data Centre Firewalls apply granular security policies using VXLAN/VLAN tagging, micro-segmentation, and user identity through FortiAuthenticator. Zero Trust Network Access (ZTNA) ensures that every user, device, and application is continuously verified, preventing lateral movement across workloads and tenants.

Q2. What makes Fortinet Firewalls suitable for hyperscale data centres?

High-end FortiGate models leverage Fortinet’s NP7 processors to deliver multi-terabit throughput with sub-microsecond latency. Hardware acceleration offloads intensive tasks such as intrusion prevention and SSL inspection, enabling secure operations in hyperscale environments without impacting application performance.

Q3. How do Fortinet Firewalls manage encrypted traffic at massive scale?

With dedicated SSL/TLS inspection hardware, Fortinet Firewalls can decrypt and inspect encrypted traffic (including TLS 1.3) at line rate. This allows enterprises to maintain visibility across over 80% of encrypted traffic without creating bottlenecks or blind spots.

Q4. How do Fortinet Firewalls integrate with SDN and automation frameworks?

Fortinet provides APIs, Ansible modules, and direct integrations with VMware NSX, Cisco ACI, and OpenStack. This enables policy-driven automation where firewall rules adapt dynamically to workload changes, supporting agile, software-defined data centre environments.

Q5: How do Fortinet Firewalls mitigate DDoS and high-volume attack scenarios?

FortiGate firewalls feature hardware-accelerated DDoS protection, anomaly detection, and rate-limiting to block volumetric and application-layer attacks. They can also integrate with FortiDDoS appliances for advanced, layered mitigation in large-scale environments.

Q6: What support options are provided under FortiCare?

FortiCare offers flexible global support ranging from 8×5 business-hour cover to 24×7 mission-critical support. Options include advanced hardware replacement, firmware updates, and direct access to Fortinet engineers, ensuring organisations maintain uptime and compliance.
