It gave us our "Mean Time to Innocence." Now, when the network is "slow," I can instantly prove it’s a specific user or a backup job rather than a hardware fault. A solid, reliable daily tool.

NBAR2 support is the best part; it finally lets us see that our "unknown" traffic was just unthrottled 4K streaming. The bandwidth billing module also made ISP overage disputes much easier to win.

The initial flow export config on our multi-vendor switches was a pain; the templates aren't always up to date. Also, rendering historical reports for 30+ days of raw data can be quite sluggish.

Overall, NetFlow Analyzer delivers excellent network insights, making it a valuable solution for IT teams managing complex infrastructures.
