For a mid-size office that has outgrown a desktop firewall: 1RU, dual power, a dedicated HA port, and enough GE, SFP and 10G ports to terminate the core switch stack directly.
Buy it by part number. We can move you onto it for a fixed fee: $8,900 for this class or an HA pair; see firewall migration.

No DC model in the 120G line. The 120G and 121G use different bundle and renewal part numbers (F120G and F121G), so tell us which one is installed when you renew. The price list also carries an FG-121G-LENC appliance with no matching bundles; the datasheet does not cover it, so it is not listed here.

Source: Fortinet FortiGate 120G Series datasheet, FG-120G-DAT-R19-20260929 (2026-09-29). 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 120G included. The datasheet still prints tunnel-mode figures, but they do not apply to current firmware. 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 120G vs 90G and 200G
The neighbouring models, compared on the same datasheet figures.
Against the 90G ($3,638 list), the 120G is only modestly faster (2.8 Gbps threat protection against 2.2, 5.3 Gbps IPS against 4.5) but moves to 1RU with dual built-in power, a dedicated HA port, 16 GE RJ45, 8 GE SFP and four 10G SFP+ cages instead of eight GE ports and two shared-media 10G WANs.
The 200G ($11,477 list) roughly doubles inspection: 6 Gbps threat protection, 7 Gbps SSL inspection and 11 M sessions against 2.8, 3 and 3 M. It also adds eight 5G copper ports, eight 10G cages and up to 25 VDOMs. Pick it when most traffic is inspected or the site is a regional hub.

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Fortinet's datasheet does not name a predecessor for the 120G series, and we do not publish a guessed mapping. We check your current unit's lifecycle dates and Trade-Up eligibility per serial number, then size on measured traffic with inspection on. See FortiGate end-of-life replacement.
Ports and optics
Sixteen GE RJ45, eight GE SFP and four 10G SFP+, plus separate HA and management ports. The four 10G cages are FortiLink ports by default and can be reconfigured as regular interfaces. The datasheet lists no included transceivers, so SFP and SFP+ optics or DACs go on the quote. There are no 2.5G or 5G copper ports; for a multi-gig handoff, look at the 200G.
HA pair
The dedicated GE HA port carries heartbeat without using a data port; Fortinet recommends at least two heartbeat links, so add one GE port cabled directly between the units. Each unit needs its own bundle, and the current price list has no 120G HA SKU: an HA pair on 3-year UTP comes to $27,654 on Fortinet's price list, shown for reference. Each unit has two built-in supplies; feed them from separate circuits. They are not hot-swappable, so a failed supply is an RMA, not a field swap.
FortiManager onboarding
New units are created in FortiManager as model devices by serial number and staged before shipping, so the config installs when the box first connects. Replacements go through config conversion plus a hand check of interface mapping, removed features and policies.
Sizing caveats
Inspection figures are close to the 90G's: 2.8 Gbps threat protection and 3 Gbps SSL inspection at 2,100 new inspected sessions per second. The 120G buys ports, rack mounting, dual power and an HA port more than raw inspection headroom. If most traffic is deep-inspected above 2 to 3 Gbps, size the 200G. No local disk on the 120G: logs go to FortiAnalyzer, FortiAnalyzer Cloud or FortiGate Cloud.
120G or 121G
The only datasheet differences are the 121G's 480 GB SSD and slightly higher power draw. The FG-121G lists at $6,337 against $5,511. If logs go to FortiAnalyzer and disk-based features are not required, the 120G is usually the better buy.

FortiGate 120G questions
How much does a FortiGate 120G cost?
Fortinet list price is $5,511 for the appliance alone, $8,283 with 1 year of FortiCare Premium and UTP, $13,827 for 3 years and $19,371 for 5 years (price list effective 2026-09-07). Your quote confirms current pricing, tax and shipping.
FortiGate 120G or 121G?
Same ports and performance figures. The 121G adds a 480 GB SSD for local logging and disk-based features. If logs are centralized in FortiAnalyzer, the 120G is usually enough.
Are the 120G power supplies hot-swappable?
No. The datasheet lists dual built-in, non-swappable AC supplies for 1+1 redundancy. The unit keeps running on one supply, but replacing a failed one means an RMA.
Does the 120G support SSL-VPN?
Not in tunnel mode on FortiOS 7.6.3 or later; Fortinet removed it from all models. Full-tunnel remote access is IPsec (IKEv2); ZTNA covers access to individual applications.
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 ($792 per year list for FortiCare Premium on a 120G), 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.
