What is the purpose of an email filter?

The purpose of an email filter is to analyze the content of incoming emails along with the reputation of the sender in order to identify and mitigate potential security threats. This process involves scanning the email for malicious attachments, links, spam characteristics, and other indicators of spam or phishing attacks. By evaluating both the email's content and the sender's credibility, email filters play a critical role in protecting users and systems from cyber threats.

This proactive measure is crucial for organizations, especially in the maritime sector, where sensitive data can be at risk. The efficiency of an email filter helps to ensure that legitimate communications are received while harmful emails are blocked, thus enhancing overall cybersecurity practices.
