Which one fits
The FortiGate 900G is not a straight step up from the FortiGate 700G: it publishes less threat-protection throughput (20 Gbps against 26 Gbps) and IPS throughput (26 Gbps against 38 Gbps). It gains TLS inspection throughput from 14 Gbps to 16.7 Gbps (+19%) and the TLS handshake rate from 13,000 to 18,000 (+38%). Neither choice moves the concurrent session table (both 16 million) or the session setup rate (700,000 against 720,000), so a site held back by how many flows can be live at once gains nothing from the FG-900G.
Choose the FortiGate 700G if
- TLS inspection throughput is already enough at 14 Gbps: the FG-900G adds +19% you will not use.
- The FG-700G is ahead on threat-protection throughput: 26 Gbps against 20 Gbps.
- The FG-700G is ahead on IPS throughput: 38 Gbps against 26 Gbps.
- Your limit is how many flows can be live at once, which the step up does not move: 16 million against 16 million.
Choose the FortiGate 900G if
- TLS inspection throughput has to go past 14 Gbps: the FG-900G publishes 16.7 Gbps.
- The TLS handshake rate has to go past 13,000: the FG-900G publishes 18,000.
- Application control throughput has to go past 50 Gbps: the FG-900G publishes 74.8 Gbps.
- The FG-900G has 16 × GE RJ45 Slots against 8.
27 of the 61 published rows are identical — Trusted Platform Module at Yes, Firewall Policies at 10,000, Gateway-to-Gateway IPsec VPN Tunnels at 2,000 and Client-to-Gateway IPsec VPN Tunnels at 50,000 among them — so the choice does not touch any of those.
