Email spam filtering protects email and employees from spam that can deliver malware, zero-day attacks and other advanced threats.

What is email spam filtering?

Email spam filtering protects email and employees from spam that can deliver malware, zero-day attacks and other advanced threats, and spread throughout the enterprise. Incorporating an email spam filter not only helps to protect against advanced cyberattacks, but will prevent inboxes from filling up with unproductive junk mail.

There are different types of spam filters for different criteria:

  • Content filters – parse the content of messages, scanning for words that are commonly used in spam emails.
  • Header filters – examine the email header source to look for suspicious information (such as spammer email addresses).
  • Blocklist filters – stop emails that come from a blocklist of suspicious IP addresses. Some filters go further and check the IP reputation of the IP address.
  • Rules-based filters – apply customized rules designed by the organization to exclude emails from specific senders, or emails containing specific words in their subject line or body.

What do spam filters look for?

To be truly effective, spam filters must scan every incoming email in real time and block many forms of malware such as suspicious URLs, suspicious attachments, and social engineering attacks such as phishing.

Why is spam filtering important?

Email spam is one of the oldest and most prevalent methods of attack against organizations. Cybercriminals can deliver spam quickly and inexpensively at huge volumes, making it difficult to block without spam filtering. And since spam can deliver malicious activity like zero-day attacks, phishing, and malware, it’s critical to use spam filtering to protect organizations.
