Email filters are programs that help manage the flow of incoming emails by organizing them into categories based on different criteria. By doing so, they make our lives easier by eliminating the need to manually sort through every email that lands in our inbox. But there’s more to email filtering than just convenience: it also plays a critical role in cybersecurity.
What is an email filter?
An email filter is a program that sorts emails into different folders based on specific criteria such as sender’s email address, subject or content. For instance, you could configure your email filter to send all emails from your colleagues to a “work” folder and all emails about deals and promotions to a “promo” folder. This way, your inbox only displays the emails that matter while the rest go directly to designated folders.
Why is email filtering important?
Email filtering is an essential component of cybersecurity. Email filtering services scan incoming and outgoing emails to detect and prevent spam, malware, viruses, and phishing attacks. By filtering malicious traffic at the email gateway, these services protect users and organizations from cyber threats.
How do email filters work?
Email filters work by scanning incoming emails and either accepting them or rejecting them based on preset criteria. They can be cloud-based or deployed as on-premises appliances. An inbound email filter, for example, scans messages addressed to users and categorizes them into different categories like spam, malware, bulk, impostor, and more. Outbound email filtering, on the other hand, scans messages from users before forwarding potentially harmful ones to other organizations.
Email filters can also be configured to send incoming emails to different folders based on preset criteria. For instance, all emails marked “work” will go into a “work” folder while suspicious emails are sent to the Junk or Spam folder.
Conclusion
If you’re looking to streamline your inbox and protect your organization from cyber threats, email filtering is the way to go. By automatically organizing your emails into different categories and scanning for malicious traffic, you can improve productivity and reduce the risk of falling victim to email scams.
