secure messaging

Question

until now i have not seen any safe way to send messages and ios and windows, linux aso are anyway not safe, if that were safe, there wouldnt be solutions for enterprises. Anyway Is there another way in XG to send save messages? Or is it at any program of sophos possible to send safe messages?

Michael, 
 if you want to send safe messages, you need to use encryption. Make sure to encrypt the message (for email, messages, files, data in general). The best way is to digital signature that relies on PKI. With digital signature you can meet Authentication, Confidentiality, Privacy and Non-repudation. 
 More info on how to use PKI and digital signature on google, wiki. With XG, you can use SPX to send encrypted emails. https://community.sophos.com/kb/en-us/123114
