With an inline deployment, emails are thoroughly examined before it reaches a recipient’s inbox. Email Gateway Defense becomes a step in the SMTP processing sequence and actively engages with incoming email messages. Based on your policies, various messages are blocked before reaching the inbox.
Benefits
An inline deployment provides customers with layered security and filtering. Filtering messages in a gateway helps to ensure that malicious emails are never delivered. Finally, an API integration with Barracuda Impersonation Protection provides post-delivery detection and protection.
Another benefit to inline deployment is the ability to improve email security without depending on changes to DNS MX records. This is particularly helpful when various teams manage different aspects of your organization.
Limitations
Inline deployments are not without disadvantages. For example, email continuity and spooling are not available.
