Firewall log rate: 600 events/s per device

A firewall source typically produces 600 events per second per device, bursting to 3,000: per appliance; TLS inspection multiplies it. The rate is an informed estimate, a starting point for a sizing, not a measurement; the event sizes below are measured.

Measured sources in this category

Average bytes per event, measured, and one device's volume at the typical 600 events per second.

At the median size, a day from one device, 23.6 GB, is about the size of a Blu-Ray disc.

Measure a sample of your own

The figure above is an average; yours will differ, and for firewall logs what moves it most is this: per appliance; TLS inspection multiplies it. The profiler reads a sample from firewall logs in your browser, line by line, one event per line, and reports the bytes per line to set against it. Nothing is uploaded.
