Licensing and lifecycle
FortiGuard licensing and support
FortiGuard services and FortiCare support depend on the purchased bundle or subscription; hardware alone does not imply that all services are included.
Hyperscale licensing
The datasheet lists a separate Hyperscale licence for session acceleration functions; confirm the SKU and availability.
SSL-VPN and FortiOS version
Published historical capacity; SSL-VPN tunnel mode was removed from all models as of FortiOS 7.6.3 and replaced by IPsec VPN. SSL inspection is a separate function.
Lifecycle and document review
End of Order / End of Support are not stated in this datasheet; confirm the official milestones for each SKU before purchasing.
Figures published by the manufacturer. Final sizing depends on the environment, enabled services and traffic profile.
