FortiGate VM02V
Two vCPUs, 15 Gbps of firewall throughput and up to 25 VDOMs — the first step up where one core has run out of headroom.

FortiGate VM02V vs FortiGate VM04V
Of the 22 specifications Fortinet publishes across these two models, 16 differ. The differences are listed first, then what the step up actually buys and which model fits which site, then every row side by side.
The two models
FortiGate VM04V
Four vCPUs and 28 Gbps of firewall throughput, with up to 50 VDOMs and 8,000 registered endpoints for a busy virtual segment.

Which one fits
Stepping up from the FortiGate VM02V to the FortiGate VM04V moves threat-protection throughput from 1.2 Gbps to 2.0 Gbps (1.7×), IPS throughput from 5.5 Gbps / 1.5 Gbps to 8.0 Gbps / 3.0 Gbps (+45%) and NGFW throughput from 1.5 Gbps to 2.5 Gbps (1.7×). Neither choice moves the site-to-site tunnel count (both 2,000) or the controlled-AP limit (both 256 / 512), so a site held back by how many branches terminate on it gains nothing from the FG-VM04V.
Choose the FortiGate VM02V if
- Threat-protection throughput is already enough at 1.2 Gbps: the FG-VM04V adds 1.7× you will not use.
- Your limit is how many branches terminate on it, which the step up does not move: 2,000 against 2,000.
Choose the FortiGate VM04V if
- Threat-protection throughput has to go past 1.2 Gbps: the FG-VM04V publishes 2.0 Gbps.
- IPS throughput has to go past 5.5 Gbps / 1.5 Gbps: the FG-VM04V publishes 8.0 Gbps / 3.0 Gbps.
- NGFW throughput has to go past 1.5 Gbps: the FG-VM04V publishes 2.5 Gbps.
- The concurrent session table has to go past 2.6 Million: the FG-VM04V publishes 4.3 Million.
6 of the 22 published rows are identical — Network Interface Support at 1 / 10, Storage Support at 32 GB / 2 TB, Firewall Policies at 50,000 / 100,000 and Unlimited User License at Yes among them — so the choice does not touch any of those.
