Email is a great way to communicate with staff, colleagues, business partners, vendors, contractors, etc. However, normal email communications are not a very secure method of communication especially when sensitive data needs to be sent. The preferred method to securely send an email containing sensitive data is to use encryption.
Encryption allows for email communication to be secured between the sending and receiving parties.
