Easy to use, quick loading times for alerts. It's not free but there are no hidden costs either. I have used it mainly to identify attacks from my network infrastructure. The UI looks very basic so you need some knowledge about how this software works before using it. If you're looking at something that will help your organisation understand its own networks better, then do give it a try! You won't be disappointed. We've been able to see what devices/IP addresses are being attacked and where they come from.
