The FortiAnalyzer 3750G ingests 8,300 GB of logs per day, sustaining 100,000 logs/sec in analytic mode and 150,000 logs/sec in collector mode, with 24x 16 TB HDD + 4x 15 TB SSD of storage.
8,300 GB/day, 100,000 logs/sec analytic and 24x 16 TB of HDD with 4x 15 TB SSD, the largest FortiAnalyzer, aimed at carriers and very large service providers. At this scale, log architecture is a design exercise: collectors, retention tiering and search behaviour all need scoping before a model is chosen.
How to work out whether it fits
The arithmetic a datasheet leaves out. If any of it does not match your situation, that is worth a call rather than a guess.
At 8,300 GB/day and 100,000 logs per second, log architecture is a design exercise rather than a purchase. Collector placement, retention tiering and search behaviour all need scoping, and the appliance follows from that. Bring us the estate and the retention obligation; sizing this from a spec sheet is how organisations end up with capacity they cannot search.
What to order alongside the FortiAnalyzer 3750G
The published threat protection figure for this model is measured with IPS, application control and malware protection all running. Those arrive as a FortiGuard subscription, so the bundle you choose decides whether the hardware can reach the number you sized it on. Every bundle already includes FortiCare Premium 24x7 support.
| Bundle | What it adds | 1 yearlist price | 3 yearslist price | 5 yearslist price |
|---|---|---|---|---|
| Enterprise ProtectionENT | The broadest bundle. Everything in UTP, plus the services that cover data, SaaS posture and attack-surface visibility, plus inline zero-day malware prevention. | on quote | on quote | on quote |
| Unified Threat ProtectionUTP | The traditional mid-tier: perimeter defence covering network, file, web and email threats. Everything most sites actually switch on. | on quote | on quote | on quote |
| Advanced Threat ProtectionATP | The narrow bundle: IPS and the full malware stack including cloud sandboxing, without the web and email filtering layers. | on quote | on quote | on quote |
These are Fortinet list prices. You will not pay them.
Every quote we write is discounted from list, and how far below depends on quantity, term and whether we register the deal with Fortinet. Longer terms also price better per year, which is why three and five year bundles are usually the better buy on a device you intend to keep through a refresh cycle. Part numbers follow Fortinet’s standard bundled convention; not every model carries every combination, so we confirm the exact orderable SKU before anything is placed.

What this includes
Fortinet publishes no throughput table for this product; it is licensed per user, endpoint, workload or account. What follows is capability and sizing, not benchmarks.
Capacity
Analytic mode indexes for investigation and reporting; collector mode ingests faster but does not index. Large estates commonly run collectors at the edge feeding one analytic unit at the centre.
| GB logs/day | 8,300 |
|---|---|
| Analytic sustained rate (logs/sec) | 100,000 |
| Collector sustained rate (logs/sec) | 150,000 |
Hardware
| Total interfaces | 2x 10GE RJ45, 2x 25GE SFP28 |
