What is one of the main duties of a Secure Email Gateway (SEG)?

A Secure Email Gateway (SEG) primarily functions to enhance the security of email communications within an organization. One of its main duties is to filter out spam and malicious content. This process involves evaluating incoming and outgoing emails for potential threats, including phishing attempts, malware attachments, and unwanted spam messages. By using advanced filtering techniques such as reputation checking, content analysis, and machine learning algorithms, the SEG helps ensure that only safe and relevant emails reach users, thereby protecting the organization from various cyber threats.

This filtering capability significantly contributes to reducing the risk of data breaches and ensuring compliance with security policies, making it an essential tool for any organization that relies heavily on email communication. In contrast, while archiving emails, managing user accounts, and improving email delivery speed may have their own importance in email management, they do not align with the core functions of a Secure Email Gateway, which is primarily focused on maintaining email security against threats.
