Trellix Email Security

Formerly FireEye Email Security

It has a very good feature of URL replace, it helps us to block or prevent spam, phishing, or malicious emails. It has some limitations like if some large or lengthy emails come it takes more time to scan and to avoid delay it forwards the mail to the recipient with a warning note on it.

Complete email security protection against all email users. it also works well with O365 email ATP as well. Both do retrospective alerts. It's like watching a dance between 2 products. They typically don't retro the same email. They fingerprint emails for future blocking. Provides a higher level of security for emails and ease in identifying abnormalities.

I would highly recommend FireEye Email Security to a colleague. The platform is good at eliminating malicious emails prior to delivery to the end-user. Detections exist across the URL, attachment, and embedded HTML levels. It is a strong platform.

Even if you are using email security features via enterprise mail, it is the best option for securing enterprise mail. In particular, FAUDE (FireEye Advanced URL Detection Engine) has been of great help in blocking URL-based threats. If you use O365, MS365, and Gmail, you can respond to the post email delivery weaponized URL threat through the Remediation feature.

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.

FireEye as a company seems very good overall. We are evaluating other security products from them as I write this and I have to say when it comes to security itself and customer support they appear to be very good. We had another spam filtering product that seemed to work well, but a few years back when security content became a bigger issue than spam content we decided to evaluate new products and chose ES. The product seems to work very well at blocking the bad stuff and allowing good stuff and is easy to monitor and manage. The company is very responsive and helpful. The ES cloud application itself is consistently upgraded and improved. The way you implement the product is very easy. We have begun testing the O365 hybrid scenario and ES works very well in this scenario.
