In the early days of email, spam was just annoying. Now, it’s dangerous for both inbound and outbound email message. Email is now the most common entry point for network threats like malware, phishing attacks and ransomware. Lost productivity from checking and deleting spam and the expense of calling in the IT department to fix and recover lost data costs over $20 billion a year.
