Email security is a process of predicting, preventing, detecting, and responding to attacks. A comprehensive security approach to email encompasses firewalls, email systems, content protection, user behavior, and other related processes. In order to effectively secure emails, you must select products with the right capabilities and configurations, as well as ensure that your operational procedures are appropriate. A vast variety of solutions and capabilities for email security are available
Secure Email Gateway (SEG) SEGs have traditionally protected incoming and outgoing emails for on-premise systems, whether they were local appliances, virtual appliances, or cloud solutions. A SEG's functions include filtering SMTP traffic and modifying the mail exchange record that points to the SEG.
Integrated Cloud Email Security (ICES) Cloud email providers, such as Google and Microsoft, are becoming increasingly popular thanks to their built-in hygiene features. SEGs are less effective for cloud email systems. Therefore, the majority of advanced email security solutions today are ICESs.
ICES is more than just a malicious content filter. It offers in-line prompts that increase security awareness through training and detection of compromised internal accounts in addition to blocking malicious content.
