What is the main purpose of data classification in an SEG?

The main purpose of data classification in a Secure Email Gateway (SEG) is to identify sensitive data for better protection. This involves categorizing email content based on its sensitivity, helping organizations manage sensitive information effectively. By classifying data, organizations can apply the appropriate security measures like encryption or access controls to protect it from unauthorized access or data breaches. This process is critical in ensuring compliance with regulations, safeguarding personal and financial information, and maintaining the overall security posture of the organization.

The effectiveness of an SEG relies heavily on its ability to discern between different types of data, enabling it to enforce policies pertinent to each class, ultimately enhancing data security management.
