Use Cases and Deployment Scope

We use it as an email gateway for the company. All email addressed to our employee's email addresses are routed through the appliance. It attempts to filter out some malicious emails based on the links and attachments that are found. It is not our only email defense that we have in our stack.

Pros and Cons

It does a decent job of detecting malicious attachments in emails.
It is easy to release emails that are incorrectly quarantined.

The interface is not exactly intuitive.
There are a high number of false positives.
To my knowledge, there is not a way to whitelist links or attachments.

Return on Investment

It's been positive in the sense that it has blocked some malicious email that would have otherwise made it to our users.
It has been negative in the sense that we spend a higher-than-expected number of cycles dealing with false positives.
Another negative is that we also experience false negatives.

Alternatives Considered

I was not involved in the evaluation of FireEye Email Security, as it was done before I was in my current role. So, I am not aware of which other tools were evaluated.

Support Rating

The reason that I gave the support a 5 is that I have had both positive and negative experiences. One of the positive experiences was when a senior support engineer spend quite a few hours with me solving an issue that we were having. One of the negative ones was when we were experiencing an issue and one person from support gave one solution, and when the issue reoccurred we were told by another person that what was recommended to us the first time was incorrect. The issue was never fully solved.

Likelihood to Recommend

It works well as one component of an email security stack, as long as you do not mind dealing with false positives. It would not be suitable as the only component in an email security system. When upstream components of our stack have gone down, a high number of malicious mail got through our FireEye appliance.
