Sizing a high-end FortiGate.
Match throughput and interfaces to your core, not just user count.
Lead with threat protection throughput
With full inspection on, threat protection throughput is the number that matters, not raw firewall throughput.
Plan your interfaces
High-end cores need 25, 100, or 400 GE. We confirm the interface mix your topology needs.
Build in headroom
Data center traffic grows. We size with room so the firewall is not the bottleneck in two years.
