FireEye analyzed over half-a-billion emails from 1H 2018, and found that 32% of email traffic seen in the first half of 2018 was considered ‘clean’ and actually delivered to an inbox. Their report also found that 1 in every 101 emails had malicious intent. When compared to the previous six-month period, the changes in both these numbers depict that the email landscape continues to see an increase in email-based threats.
