Easy to use user interface with no lag time between messages in inbox. The application can be sync across multiple devices like android/ios phones, tablets etc.The best feature is that it provides end-to-end encryption so there's not any way for anyone with access to our account (i.e users) to view unread messages even if they decrypt them. I would recommend this app just because of its ease of use. It does require some training initially, but once trained we found the system very easy to navigate through. If you're looking for an encrypted messaging platform where your communication data remain safe and secure from prying eyes then cirius is definitely what you want! This was one of my solutions to make sure all communications are private as far as being able to send confidential information. The ease of use as well as its wide range of features really make this platform stand out from others in our industry. I can’t think of anything that we dislike about it! We have been able to track customer communication with clients for years now without any issues at all. It has made managing emails much easier than before since every message sent by us gets tracked within seconds.
