How does machine learning enhance the capabilities of a Secure Email Gateway?

Machine learning significantly enhances the capabilities of a Secure Email Gateway by identifying patterns and anomalies in email traffic. This technology enables the SEG to analyze vast amounts of data and learn from it, improving its ability to detect suspicious behaviors and potential threats.

With machine learning algorithms, the SEG can adapt to evolving tactics used by cybercriminals, such as phishing and malware distribution. It can recognize subtle deviations from normal email patterns, which might indicate a security threat. For example, if an email that typically comes from a trusted source starts exhibiting unusual characteristics, the SEG can flag it for further inspection or quarantine it altogether.

This proactive approach to threat detection not only helps in minimizing false positives but also ensures a more robust response to emerging email-based threats. By continuously learning from new data, the SEG becomes increasingly effective over time, making it a critical component in protecting organizations against sophisticated email attacks.
