Helpful support, and useful dashboards
They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

Gateway filtering has protected our organization and provides complete email threat prevention
In my opinion, the best features Trellix Email Security offers include its use for malware analysis as well as the enterprise-wide email quarantine system. My experience with the malware analysis and quarantine features is that they are easy to manage and they have been very effective because we have been able to quarantine any suspicious emails or prevent any attempt before it affects our systems. It is also very user-friendly and has a simple interface. Policies and rules are easy to create and they work with very little downtime or operational impact. Email delivery issues are easy to investigate and troubleshoot. Trellix Email Security has positively impacted my organization as it is user-friendly and does a good job detecting malicious attachments in email, providing complete email protection against all users and working well to stop advanced threats. The price is relatively the same as other competitors.

"Although the number of AV engines is good, it could be better."
