If a load balancer isn’t used, the MX records often point to the public IP address of a specific MTA. After the e-mails have been processed by the mail security appliances, they are forwarded to the Exchange backend. Such setups are quite common. Sometimes the e-mails are not directly forwarded to the Exchange servers, but to mail security appliances instead (like Zertificon Z1 SecureMail Gateway). But things may change.The inbound SMTP connections are distributed to two Mail Transfer Agents (often a cluster of appliances, like Cisco IronPort or Symantec Messaging Gateway) and the MTAs forward the e-mails to the Exchange servers. It's not best of breed for email, compared to Microsoft's EDR product for example. Proofpoint is rolling this out as well (CLEAR)Ĭurrently ATP is immature, in my opinion. That being said, you do want the remediation features of say Cisco API-based which makes it easier to pull mails in retrospect. The MX boxes of Proofpoint and Cisco works as your current Ironport VM - they are separately spun-up VMs with a dedicated IP you have more control over. you are going with Microsoft Online so what's with the cloud scare?Īnd how do you correlate threats? Secure X for example isn't really feasible without a cloud connection If you are paranoid over Cisco "getting all your emails" I take it you do not have Windows as the client OS' and that you. What does this even mean? Why spin up an "Ironport VM" if you can spin up the Cisco MX ESA? Or Cisco Secure Email api based. but we do look for simplicity whenever possible. Can't give away all our emails to Proofpoint, Mimecast or even Cisco Cloud.
