Which one fits
Stepping up from the FortiGate VM08V to the FortiGate VM16V moves threat-protection throughput from 3.5 Gbps to 7.0 Gbps (2×), IPS throughput from 15.5 Gbps / 6.0 Gbps to 25.0 Gbps / 12.0 Gbps (1.6×) and NGFW throughput from 4.5 Gbps to 9.0 Gbps (2×). Neither choice moves raw firewall throughput (33 Gbps against 36 Gbps) or the site-to-site tunnel count (both 40,000), so a site held back by uninspected forwarding gains nothing from the FG-VM16V.
Choose the FortiGate VM08V if
- Threat-protection throughput is already enough at 3.5 Gbps: the FG-VM16V adds 2× you will not use.
- Your limit is uninspected forwarding, which the step up does not move: 33 Gbps against 36 Gbps.
Choose the FortiGate VM16V if
- Threat-protection throughput has to go past 3.5 Gbps: the FG-VM16V publishes 7.0 Gbps.
- IPS throughput has to go past 15.5 Gbps / 6.0 Gbps: the FG-VM16V publishes 25.0 Gbps / 12.0 Gbps.
- NGFW throughput has to go past 4.5 Gbps: the FG-VM16V publishes 9.0 Gbps.
- The concurrent session table has to go past 8.5 Million: the FG-VM16V publishes 18.0 Million.
9 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.
