What is Secure Email Gateway (SEG)?
A Secure Email Gateway (SEG) is an essential email security solution that leverages signature analysis and machine learning to detect and block malicious emails before they can reach recipients' inboxes. Given that email-based attacks, such as phishing, are among the most prevalent cyber threats facing organizations today, SEGs play a critical role in safeguarding communication channels.
SEGs operate similarly to secure web gateways (SWGs) but are specifically focused on analyzing and securing email traffic rather than web browsing activity. Initially, SEGs were developed to combat spam, which provided ample data for identifying and blocking malicious content. However, as email threats have evolved to become more targeted and sophisticated—such as in the case of business email compromise (BEC) attacks, which may lack overtly malicious elements like phishing links or malware—modern SEGs now incorporate machine learning and threat intelligence to detect and prevent these advanced threats, along with other emerging risks.
