Description
Fortinet FortiGate 1800F Series (FG-1800F / FG-1801F / FG-1800F-DC / FG-1801F-DC)
“Datacentre / core NGFW with real 100G uplinks, high threat throughput, and hyperscale session performance (with license).”
This is the step up when you need more ‘real-world security’ throughput than 1000F/1100E and you want 100GE QSFP28 in the same box.
At-a-glance performance (Enterprise Traffic Mix)
-
IPS: 22 Gbps
-
NGFW: 17 Gbps
-
Threat Protection: 15 Gbps
-
SSL Inspection (IPS avg HTTPS): 12 Gbps
-
IPsec VPN (512B): 55 Gbps
-
SSL-VPN: 11 Gbps
-
Recommended concurrent SSL-VPN users: 10,000
What this means: it’s built for high-volume encrypted traffic + full security stack, without turning the firewall into the choke point.
Ports & interfaces (what you’re really buying)
-
4 × 100GE QSFP28 / 40GE QSFP+ (100G requires FortiOS 7.0.16+, 7.2.8+, 7.4+, or 7.6+ per sheet)
-
12 × 25GE SFP28 / 10GE SFP+ / GE SFP
-
2 × 10GE SFP+ / GE SFP HA slots
-
8 × GE SFP
-
16 × GE RJ45
-
2 × GE RJ45 management
-
Console + USB 3.0
Why it matters: you can do core segmentation + high-speed aggregation with 100G uplinks and still have a ton of port flexibility for mixed environments.
Scale & capacity (enterprise / hyperscale-ready)
-
IPv4 firewall throughput (1518/512/64 UDP): 198 / 197 / 140 Gbps
-
Latency (64B UDP): 3.22 μs
-
Firewall throughput: 210 Mpps
-
Concurrent sessions (TCP): 12M / 40M*
-
New sessions/sec: 750k / 2M*
-
Firewall policies: 100,000
-
VDOMs: 10 default / 250 max
-
IPsec tunnels (G2G): 20,000
-
IPsec tunnels (Client): 100,000
-
Max FortiAPs: 4096 total / 2048 tunnel
-
Max FortiSwitches: 196
-
FortiTokens: 20,000
* The “40M sessions / 2M new sessions/sec” figures require the Hyperscale Firewall License (important line-item/upsell).
