Use cases

Typical flows

• Mail out of the internal network

  The internal mail server, with no path of its own to the Internet, hands mail to the outer network's server.

• Mail in from outside

  Your outer gateway passes on mail it has already inspected, and AMG carries it across to the internal server.

• Operational alerts

  Monitoring notices from an isolated network reach the support team outside.

• Government and sensitive networks

  Email between separated government or sensitive environments.

• Critical infrastructure and OT

  Operational email between isolated infrastructure zones and the enterprise network.

• Telecom and finance

  Mail between operational, support and enterprise domains that must stay apart.
