Deployment models

Email security offers multiple deployment models:

• API for Microsoft 365 users.
• BCC for Google Workspace users.
• MX/Inline for all email providers.

When you choose the API deployment, Email security can both scan and take actions on emails after they have reached a user's inbox.

If you are a Google Workspace user, you can enable Email security via BCC setup. Email security scans a copy of your email after it lands in your inbox.

With MX/Inline, Email security scans your email before they land in your inbox, giving you the highest level of protection.
