Sending unencrypted emails is like sending
confidential information on a postcard

  1. Email is still the most commonly used tool for business communications because of its ease of use and accessibility, regardless of the security limitations of the Simple Mail Transfer Protocol (SMTP) protocol - the standard communication protocol for electronic mail transmission. 
  2. Many webmail solutions have native encryption, but the communications can still become unencrypted on their way to the recipient, making them vulnerable to misuse.
  3. Traditional Transport Layer Security (TLS) is a cryptographic protocol providing communications security over a computer network. However, it often lacks complete end-to-end encryption.
