Email privacy refers to keeping emails secured, either while in transit or while they're stored in a server. The process of sending an email involves many hardware and software systems like the email clients, ISPs, and servers. The emails processed through these systems are susceptible to unauthorized attacks at various stages.
Businesses need to have privacy protocols in place to avoid attackers from intercepting emails. Email tampering, spam, phishing, and spoofing attacks can be avoided if these protocols are ingrained in the email system of the business.
