The FortiGate 401F includes two 480 GB SSDs for local log and event storage, while the 400F ships with no onboard storage. All performance specifications are identical across both models. If you plan to send logs to FortiAnalyzer or FortiCloud, the 400F is sufficient. If you want logs retained locally on the appliance, the 401F is the right choice.

Fortinet positions the 400F series for mid-sized to large enterprises, typically organizations supporting 300 to 500 users at a campus headquarters or a large hub branch location. The 79.5 Gbps firewall throughput and 9 Gbps threat protection give IT teams comfortable headroom to grow without replacing hardware at the next refresh cycle.

Yes. Secure SD-WAN is built into FortiOS and runs natively on the same appliance with no additional hardware required. WAN edge routing, application steering, and automatic failover all run in the same FortiGate that handles your NGFW policy. A FortiGuard SD-WAN service bundle adds SLA database updates, overlay orchestration, and FortiSASE connectivity for hybrid workforce environments.

FortiGuard services are sold in three bundles. UTP (Unified Threat Protection) covers IPS, antivirus, web and video filtering, antispam, application control, and FortiGate Cloud Sandbox. ATP (Advanced Threat Protection) covers IPS, advanced malware protection, and application control. Enterprise Protection adds DLP, AI-based inline malware prevention, attack surface security, and CASB on top of UTP. Individual services including IPS, AMP, URL and DNS filtering, and OT security can also be licensed a la carte.

Yes. FortiGate Cloud provides zero touch deployment, configuration backup, and reporting for a single unit or an entire fleet, with a free tier and a full subscription option that retains one year of logs. FortiManager Cloud is available as an add-on for centralized policy management across multiple devices. FortiAnalyzer Cloud handles logging, analytics, and compliance reporting independently of the physical appliance.
