Make a decision before mail reaches the inbox.
PhiShark Mail Gateway is for organizations that want security controls in the inbound SMTP path. It combines mail analysis with policy decisions and a quarantine workflow. Deployment is assessed with our team.
- Inbound message enters the SMTP gateway
- Analysis and tenant policy inform the decision
- Mail is delivered or held in quarantine according to policy

Designed for your environment
For teams that need a mail control point
Choose this path when your organization can place a gateway in the mail route and needs policy action before delivery.
- Inbound SMTP routing is available to configure
- Security operators need policy and quarantine workflows
- Mail flow changes can be planned with your administrators
Operational boundaries
Gateway deployment affects mail routing and needs a scoped rollout.
- Quarantine and delivery behavior follow the configured tenant policy.
- The gateway is a separate deployment from Microsoft 365 and Google Workspace mailbox integrations.
- Routing, dependencies, and rollout are reviewed with your mail team before activation.
