What is the role of a gateway in Secure Email Gateway?

The role of a gateway in a Secure Email Gateway primarily focuses on serving as a barrier that filters incoming and outgoing emails for potential threats, such as spam, viruses, phishing attempts, and other malicious content. As a crucial component of an organization's email infrastructure, the gateway assesses email messages based on predefined security policies and rules while allowing legitimate communications to pass through while blocking harmful ones.

This function is vital in maintaining the integrity and security of email communications, as it helps mitigate risks associated with cyber threats. By filtering emails before they reach the user’s inbox, the gateway protects users and the organization from potential security breaches and data loss.

In contrast, while storing emails securely, monitoring user behavior, and managing email accounts can be important functions in an overall email management or security system, they are not the primary roles associated with a Secure Email Gateway.
