Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Great protection, good privacy, and helpful support
The only thing I would like is a way to open the email that is going to quarantine. Based on the level of security, they cannot open the email to check the message. Even for the administrator, you have to create a security copy to be sent, which will lock the log support. It's not easy for an admin to check and decide if the email is good or not. That is the only thing that I'm seeing could be improved. Basically, ESET doesn't have the ability to let the administrator release an email showing the message on the email. It's not possible. If you want to have an email review, you have to select an option to send a copy. In the way that they designed the system, for security, they are not letting anyone even have the admin privileges to make this happen. Privacy is at a really high level.

An effective email security solution that provides DLP, Safe Attachment, and Safe Links
If you want extensive email security, you need to purchase a Plan 2 license. Plan 1 and Plan 2 are the two plans for Microsoft Exchange Online Protection. Some customers hesitate to purchase this product because it adds some costs to them, which is necessary for them. It would be helpful for customers if Plan 1 features were included with EOP. However, they still need to purchase Plan 2 for advanced security features. One of our clients recently requested to compare Zimbra's features with Microsoft Exchange Online Protection. Zimbra is open source, while Microsoft Exchange Online Protection is not. When I compare both the products, many free features are available in Zimbra because it is open-source software. It makes no sense to request Microsoft Exchange Online Protection add all the features people get on open-source software like Zimbra. Hence, I would say whatever features Microsoft Exchange Online Protection has are enough. Microsoft has a dedicated research team that should research and add new techniques like phishing and spamming solutions to the product.
