I like how easy it is to use, and how well documented it is as well. It's free! You can even download demo versions of the apps without paying a dime. Also, I feel the support team responds very quickly when you need help. I don't have any downsides about this service. I highly recommend using their services if your looking for a way to secure your communications. We have been able to communicate with clients from different parts of the world while still maintaining confidential information over email or text messages.
