The FortiAnalyzer 300G ingests 100 GB of logs per day, sustaining 2,000 logs/sec in analytic mode and 3,000 logs/sec in collector mode, with 2x 4 TB of storage.
100 GB/day and 2,000 logs/sec, four times the 150G on both numbers, which is the right ratio because the two constraints bind together. Storage of 2x 4 TB sets the practical retention limit: at 100 GB/day, that is roughly two and a half months before compression. If your regulator asks for a year, this is not the model regardless of log rate.
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.
Storage sets retention, and retention is usually set by regulation rather than preference. Two 4 TB disks at 100 GB/day is roughly two and a half months before compression and RAID overhead. If your obligation is twelve months, this model cannot meet it regardless of ingest rate, work the retention arithmetic first, because it eliminates models faster than log rate does.
What to order alongside the FortiAnalyzer 300G
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.
FortiAnalyzer 300G is number 2 of 7 in this family
Ranked on gb logs/day, the figure that separates these models. All values are Fortinet’s own and cited on each product page.
FortiAnalyzer 150G
25 GB/day
300% less than the FortiAnalyzer 300G. Worth it only if your measured requirement genuinely fits inside it.
FortiAnalyzer 300G
100 GB/day
7 models in this family span 25 GB/day to 8K GB/day.
FortiAnalyzer 810G
200 GB/day
100% more headroom. Worth costing if you expect growth inside the refresh cycle, replacing early is dearer than buying up once.

- Organisations producing regular compliance reporting
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 | 100 |
|---|---|
| Analytic sustained rate (logs/sec) | 2,000 |
| Collector sustained rate (logs/sec) | 3,000 |
Hardware
| Total interfaces | 4x GE RJ45 |

| Storage capacity | 2x 4 TB |
