EMAIL SECURITY

Secure email is a message, using SMTP (Simple Mail Transfer Protocol) communication, that is free from unauthorized access, attack, loss, or interception.

Sending email securely covers two levels. First, your personal privacy must be respected by encrypting the email. Second, it’s important that your organization’s policies are respected. For example, policy controls may be used to inspect content being sent to ensure that intellectual property policies are observed.

The most secure email uses a multi-layered approach to protect email in multiple ways. Gartner writes, “A layered approach is crucial due to the increasing sophistication of email threats.” in article, Guidance Framework for Building Email Security Architecture.

Outgoing messages are scanned against policies to prevent sensitive data from leaving the organization or to automatically encrypt emails to protect sensitive information. An SEG can be deployed on-prem, as a hybrid solution or as a cloud service.
