What is the purpose of content filtering in an SEG?

The purpose of content filtering in a Secure Email Gateway (SEG) is primarily to examine emails for harmful content. This process involves analyzing incoming and outgoing messages for potential threats such as malware, phishing attempts, spam, or sensitive information that should not be transmitted via email. By actively scanning the content of emails, the SEG helps protect the organization from security breaches, data loss, and other risks associated with malicious email communication.

Through content filtering, the SEG employs various techniques such as keyword scanning, heuristic analysis, and attachment examination to identify and block harmful content before it reaches the recipient's inbox. This proactive approach to email security is crucial in maintaining a safe and secure communication environment for users, ultimately reducing the likelihood of successful cyber attacks or data compromises.
