In the advanced version, you have DLP, Data Loss Prevention, but when you buy the standard version, you don't have it. One thing I would change is the number of users in the trial model. When you do the trial, you are stuck with only one hundred users. In my case, we wanted 200 users in the trial. In the end, we had to choose the 100 most important users. They should open up the trial version a bit more so that it's not limited to the number of users on the trial.
