Fortinet FortiGate FAQ

Considering FortiGate firewalls to protect your infrastructure? Our FAQ answers 8 common questions.

Q1. Which FortiGate series is best for my deployment?

 

Deployment needsKey capabilitiesBest-fit FortiGate series
Secure large campus or distributed sites with high east-west traffic and WAN edge connectivity• Next-generation firewall with consistent threat inspection
• Integrated Secure SD-WAN and VPN
• High session capacity for dense user environments
• Support for segmentation and internal network visibility		FortiGate Campus (100F to 600F).
Well suited to campus cores, large branch aggregation, and secure WAN edge deployments needing balanced performance and advanced security services.
Protect enterprise perimeters and central WAN hubs with high encrypted traffic volumes• High firewall and threat protection throughput
• Scalable session and VPN capacity
• Multi-gigabit and high-speed interface options
• Advanced security services for enterprise edge and hybrid environments		FortiGate Enterprise (1000F to 7000F).
Designed for enterprise core and perimeter roles with critical performance, scale, and flexibility requirements.
Secure data centre perimeters or internal segmentation at very high scale• Ultra-high throughput with low latency
• Very high session and connection capacity
• High-speed interfaces for data centre fabrics
• Support for large-scale east-west traffic inspection and segmentation		FortiGate Data Centre (1800F to 7080F).
Optimised for data centre and hyper-scale environments requiring line-rate security and sustained performance at scale.

Q2. 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.

Q3. 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.

Q4. 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.

Q5. 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.

Q6. 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.

Q7. 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.

Q8. How do FortiGate firewalls integrate with the wider Fortinet Security Fabric?

FortiGate firewalls are typically deployed as part of a broader Fortinet Security Fabric, combining cloud services, centralised management, identity, endpoint protection, and WAN control to extend visibility, control, and operational efficiency.
