I have experience regarding the AD part, but my focus for the last 15 years has been oriented to the network side. My experience with identity tools comes more from a network perspective.
We used NetScout at least seven years ago. Currently, we are testing and playing with Splunk, and I am about to start working with it in a week or so. Other colleagues of mine have been working with Splunk.
We are using SolarWinds Network Device Monitor for bits and pieces on the monitoring side.
There are many areas of interest. For my area specifically, we were interested in a NetFlow analyzer. There is no comparison between the previous NetFlow analyzer and what SolarWinds Network Device Monitor can do with NetFlow. Previously we were using NetScout, and there is no comparison between those two.
For the network part, we were using NetScout. For servers, which SolarWinds Network Device Monitor handles as part of its combined functionality, we were using WhatsApp Gold.
We are doing more with SolarWinds Network Device Monitor than we were doing in the past with WhatsApp Gold. When we moved to SolarWinds Network Device Monitor, the whole observability part started to grow.
