What is a secure email gateway?

A secure email gateway (SEG) is a type of software or service that is used to secure and manage email communications for an organization. It is designed to protect against threats such as phishing attacks, malware, spam, and other types of email-borne threats that can compromise the security of an organization’s email systems.

A secure email gateway typically includes features such as:

1. Anti-spam and anti-malware filtering: This helps to prevent unwanted emails and malicious attachments from reaching a user’s inbox.
2. Email encryption: This feature ensures that emails are encrypted before being transmitted, which helps to prevent unauthorized access to sensitive information.
3. Data loss prevention (DLP): This feature helps to prevent the accidental or intentional disclosure of confidential information by monitoring and blocking the transmission of sensitive data.
4. Email archiving: This feature helps to ensure that emails are stored securely and can be easily retrieved if needed for compliance or legal purposes.

Overall, a secure email gateway is an essential tool for organizations looking to protect their email systems from a wide range of threats and ensure the confidentiality, integrity, and availability of their email communications.
