The best thing about Appsian is its flexibility in data masking. I can mask any column without having to create separate masks for each column. It's also easy to use and has a lot of features. I don't like that it doesn't support more than one mask per page, so you have to delete the old mask before adding a new one. It also takes a long time to load the page with all the masks. You should try this product if you need to mask sensitive information. We are using Appsian to mask customer names and addresses.
