Published performance is “up to” under Fortinet laboratory conditions and varies with configuration. IPS, NGFW and threat protection use enterprise traffic mix with logging enabled. NGFW enables firewall, IPS and application control; threat protection also enables malware protection. Review each datasheet before sizing. Shared-media pairs are not additional independent ports.
