Transitioning from Secure Email Gateways to AI Security

This guide provides a detailed examination of the transition from traditional Secure Email Gateways (SEGs) to advanced AI-powered email security solutions within Microsoft 365. It outlines the limitations of SEGs in the face of modern email threats, including sophisticated social engineering tactics that exploit user behavior. The document details several reasons for displacing SEGs, such as their reliance on past threat data and their inability to effectively detect novel attacks. Additionally, it presents a comprehensive plan for organizations to implement a modern email security stack that integrates seamlessly with Microsoft’s existing security features. Key components of the transition include understanding the timeline for SEG displacement and the different stages involved in replacing existing systems. The guide emphasizes the necessity of adopting an email security solution that enhances built-in Microsoft protections rather than duplicating them, ultimately aiming to improve overall organizational security posture against evolving threats.
