I like that it's easy to use, very customizable for any CMS or Content Management System you're using (WordPress/WooCommerce), has great support from Vendo Security team which is always quick with answers questions regarding their product! Nothing so far really comes into mind but as they are constantly improving we should see some major changes soon :) Definitely go ahead and try this software out if your looking at other options in order too get more control over what users can do when accessing content of yours via mobile device(s). We have been able solve our issues related to user access permission management by utilizing these modules - specifically Access Control module.-.
