FortiGate 400G price and part numbers
Every part number we would put on a quote for this model, grouped the way you buy: the box alone, the box with a security bundle, or a renewal for a box you already own. Terms are 1, 3 or 5 years.
Fortinet list price (as of 2026-09-07), from the Fortinet Americas 2026 MidQ3 Price List. Your quote confirms current pricing, tax and shipping.
The 401G is the 400G plus 2x 480 GB SSD, with its own bundle and renewal part numbers (FG4H1 against FG4H0), so a 400G renewal SKU will not apply to a 401G serial. The current price list has no DC version of either model.

Source: Fortinet FortiGate 400G Series datasheet, FG-400G-DAT-R06-20261013 (2026-10-13). Fortinet states all performance values as “up to”. IPS, application control, NGFW and threat protection are measured with logging enabled; NGFW with firewall, IPS and application control on; threat protection adds malware protection. IPsec uses AES256-SHA256. SSL inspection uses an average of HTTPS sessions across cipher suites. The datasheet still lists SSL-VPN tunnel-mode figures; those do not apply on FortiOS 7.6.3 and later, so they are left out here.
SSL-VPN status. SSL-VPN tunnel mode was removed from every FortiGate in FortiOS 7.6.3, the 400G included. Browser-based web mode is still available on models that support it; tunnel mode is gone on every model. Full-tunnel remote access is IPsec (IKEv2); ZTNA covers access to individual applications. Fortinet: FortiOS 7.6.3 release notes. Background: FortiGate SSL-VPN migration.
FortiGate 400G vs 200G and 700G
The neighbouring models, compared on the same datasheet figures.
The 200G ($11,477 list) rates 6 Gbps threat protection and 7 Gbps SSL inspection against 13 and 11.5 Gbps on the 400G, and its fastest ports are eight 10G SFP+. The 400G adds four 25G SFP28 cages, sixteen GE SFP against four, 28 M sessions against 11 M, and an NP7 in place of the 200G's NP7Lite. Move up when the core uplinks at 25G or inspected traffic is near the 200G's ceiling.
The 700G ($35,066 list) is the same 1RU chassis with the same ports, power supplies and dimensions. The difference is inspection: 26 Gbps threat protection against 13, 38 Gbps IPS against 25, and 14 Gbps SSL inspection at 13,000 new sessions per second against 11.5 Gbps and 9,700. It also manages more: 128 FortiSwitches and 1,024 FortiAPs against 96 and 512. The 400G lists 3 M concurrent SSL-inspected sessions against 1.6 M on the 700G.

What we check before this model goes on a quote, from the engineer who sizes, stages and installs it.
Replacement sizing and Trade-Up
Fortinet's 400G datasheet does not name a predecessor, and we do not publish a guessed mapping. Trade-Up eligibility is per serial number, so we check your current unit's lifecycle dates against the current Trade-Up matrix, then size the 400G on your measured traffic with inspection on. See FortiGate end-of-life replacement.
HA pair design
The 400G has a dedicated 2.5GE HA port and a separate GE management port, so heartbeat and out-of-band management do not use data ports. Fortinet recommends at least two heartbeat links: the HA port plus one data port, cabled directly between the units. The two AC supplies are internal and not hot-swappable (1+1), so feed them from separate PDUs and treat a supply fault as a maintenance-window job while the other unit carries traffic. Each unit needs its own bundle and the current price list has no 400G HA SKU: a pair on 3-year UTP comes to $142,002 on Fortinet's price list, shown for reference.
Uplinks and optics
Four 25G SFP28 cages (they also take 10G SFP+), four 10G SFP+ FortiLink cages for FortiSwitch (reconfigurable as regular ports), sixteen GE SFP and eight 5G/2.5G/GE copper ports, two of them WAN1 and WAN2. Only two 1G SX optics come in the box, so 10G and 25G optics or DAC cables go on the quote as separate line items.
FortiManager onboarding
Both members are added in FortiManager as model devices by serial number and staged before they ship. For a migration from an older FortiGate or another vendor, we convert the config, rebuild interface mapping onto the new port layout, and run the old and new units side by side in a cutover window with a rollback path. VDOMs: 10 by default, up to 50.
Sizing caveats
Size on threat protection (13 Gbps) and SSL inspection (11.5 Gbps at 9,700 new inspected sessions per second), not the 164 Gbps firewall figure. A campus with many wireless clients should also check the controller limits: 96 FortiSwitches and 512 FortiAPs (256 tunnelled). There is no disk on the 400G, so logs go to FortiAnalyzer or FortiAnalyzer Cloud ($6,615 per year list).
400G or 401G
Same ports and performance figures. The 401G adds 2x 480 GB SSD for local logging and disk-based features and lists at $27,773 against $24,696. If logs are centralized in FortiAnalyzer and no disk-based feature is needed, the 400G is the usual pick.

FortiGate 400G questions
How much does a FortiGate 400G cost?
Fortinet list price is $24,696 for the appliance alone, $40,131 with 1 year of FortiCare Premium and UTP, $71,001 for 3 years and $101,871 for 5 years (price list effective 2026-09-07). The 401G with SSD lists at $27,773. Your quote confirms current pricing, tax and shipping.
What does an HA pair of 400Gs cost?
Two units, each with its own bundle. At Fortinet list prices (for reference), two FG-400G-BDL-950-36 (3 years UTP) come to $142,002, plus 10G/25G optics, which are quoted separately. The current price list has no shared-license HA SKU for the 400G.
FortiGate 400G or 401G?
Same ports and performance. The 401G adds 2x 480 GB SSD for local logging and disk-based features and lists at $27,773 against $24,696. With central logging in FortiAnalyzer, the 400G is usually enough.
Do I need a license, or can I buy just the hardware?
You can buy the appliance alone, but every FortiGate we sell carries at least FortiCare ($4,410 per year list for FortiCare Premium on a 400G), because the bare unit gets only 90 days of firmware. A bundle adds FortiGuard UTP or Enterprise Protection, and each member of an HA pair needs its own.
Does the 400G support SSL-VPN?
Not in tunnel mode on FortiOS 7.6.3 or later; Fortinet removed it from all models. Browser-based web mode is still available on models that support it. Full-tunnel remote access is IPsec (IKEv2); ZTNA covers access to individual applications.
