We have been using LEM for over 3 years now. Implementation took us just over a week, the product is so powerful that tweaking it just right took some time, but SolarWinds is awesome and provided support every step of the way. After getting it up and running, it has been providing our monthly log reviews, alerting on significant security factors, researching user activity, generating reports, and more. It has become a daily staple of my day, I just go into my report console to review network activity and run my audit reports and export them for my logs. Running monthly reports can take a long time at the end of the month, but that is the only negative thing I can say about the product. It is more sufficient than intuitive than all other products we have used before.
