The ability to set up multiple rules for each user profile is very helpful in keeping track of who has access to what data sets at any given time.
We've been using this product since it was first released (back when we were still called CSC). It's never failed us! I'm sure there will come a day where they do change something that breaks our workflow but as long as you're not doing anything too crazy then you should be fine. If you want an easy way to keep your employees from accessing information outside their scope or if you have sensitive information stored somewhere else than within your system then NovaTime can help.
