It is not complicated to set up and you can ride a wave of continuous security effects for a long time without major changes after the initial setup. It's automated, so users don't have to care too much about it. In addition, it provides detailed analysis data, so you can utilize it for 3rd party solutions if you want.

In the years we have had this service, we haven't needed much help (which is a testament to the ease of use/reliability of the product) but when we have they have been probably the best vendor I've ever dealt with when it comes to quickly addressing support call issues. We also have a very readily available engineer that has been quick to help with more complex requests.

Reduces the need for custom integrations or connectors
Works in a “single pane of glass” experience for SOC analysts
Why it matters:
Organizations already invested in Microsoft security tools gain greater contextual insight and lower operational overhead.

There are a few things FireEye Email Security does better than ProofPoint and vice versa. For example, you would think blocking .html attachments would be trivial. FireEye Email Security can be configured to do it. Proofpoint can not, and if you try to configure it, HTML gets stripped from the email content, which has a major impact on the business. On the other hand, ProofPoint has a number of additional features and bells and whistles that FireEye Email Security does not.
