eBook: Why Email Security Matters

Email: The Most Vulnerable Communication

Email is the critical business service, showing strong growth worldwide. According to Radicati’s 2017 - 2021 Email Statistics Report, there were 3.7 billion email users in 2017—and that number may grow to over 4.1 billion users by the end of 2021. Radicati estimated total email traffic in 2017 included over 269 billion emails per day—and that number should increase to over 319.6 billion daily by 2021.

Email is the lifeblood of business. Unfortunately, it’s also a channel for attackers to strike. Spam is a frequent problem for business users since it’s sometimes used to send harmful attachments to infect computers on their network.
