Why is multi-factor authentication (MFA) recommended with SEGs?

Multi-factor authentication (MFA) is recommended with Secure Email Gateways (SEGs) primarily because it adds an additional security layer beyond just passwords. Passwords alone can be vulnerable to various forms of attacks, such as phishing, brute-force attempts, or credential stuffing. By requiring multiple forms of verification, MFA significantly enhances security.

In a typical MFA setup, a user may need to provide something they know (like a password) and something they have (like a smartphone app that generates a temporary code) or something they are (such as biometric verification). This approach ensures that even if a password is compromised, unauthorized access to the SEG is still prevented, as the attacker would also need the additional factor to gain entry.

This added layer of security is essential for SEGs, which handle sensitive email communications and can be prime targets for cyber threats. Implementing MFA helps organizations protect their data and maintain the integrity of their email systems more effectively.
