Decreased our security alerts without impacting employees' work
I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace. It provides a single console for security policy and management. That is somewhat important because we used to have other products where you would have to log in to individual appliances, devices, or clusters. Having one spot to log in to or one area to go to for doing different tasks and viewing data sources, just makes it easier from a user perspective. Also, the fact that it's invisible to our end-users and doesn't affect their work is very important. Most companies don't want to have added friction or impact on their users. In addition, the combination of user-friendliness for admins, and security for the organization, works well. As a cloud-hosted solution, it provides ease of use.

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.
