Secure Email Gateway Software Overview

Secure email gateway software prevents the transmission of malicious emails that violate company policy or contain malware social engineering attacks, spam or other unwanted emails designed to inflict damage. In this way, Secure Email Gateway software is like a firewall for your email. SEGs were originally intended for on-premise environments but have evolved to better secure cloud email environments as well.

Businesses use secure email gateway software to protect their system from attack, and to lessen opportunities for user error from social engineering attacks. There are many different ways of deploying email gateway software. Some software products are installed directly on the email server, while others are provided as a hardware appliance or virtual hardware appliance. Many secure email gateway products are available as public cloud services.

All Secure Email Gateways prevent attacks from reaching their intended recipients. Many SEG providers also offer data loss prevention capabilities. DLP features prevent leakage of sensitive information in outbound emails. Data loss prevention capabilities allow businesses to more effectively protect against internal threats, including both employees who have been compromised by social engineering attacks or who may themselves be bad actors. DLP is especially crucial when working with sensitive or proprietary information, or when required for regulatory compliance.
