"There are several features that I consider valuable."
"Defender helps us prioritize threats across our organization."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"Does a thorough job of examining email and URLs for malicious content."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Since we have started using the solution, there have been fewer compromises."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"It offers an easy initial setup."
"We like the content filtering and secure messaging features."
"The solution is pretty straightforward to use and easy to set up."
"The solution's performance is good."

"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"There's room for improvement regarding the time frame for retrieving emails."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"We need to be able to whitelist data at the backend."
"The price could be better, it should be reduced."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The attachment scanning feature doesn't work properly."
"The filtering needs more flexibility."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"External security features need improvement."
"I'd like to have better support from the product in the future."
"The feature that should be included is to remove the block on the encrypted files."

In my opinion, all gateways including Mimecast or Defender for O365 or ProofPoint work hand-in-hand in their respective mechanics and algorithms built. And definitely has its own advantages. However, I have been using it for my customers' MDO which is far better. I would say relying on gateways is important but at the same time USER education and reporting back to the IT administrator far important as well.
Greetings Matingou, Defender for O365 I would say would suffice as it has all the tools included in Mimecast in just one single tool, may take some time to navigate at first as it gives a lot of information in just one tool but once you know your way around, you will be able to have good visibility on your email threats landscape by provides a range of protections against email-based threats such as spam, phishing, malware, and etc. It also includes features such as URL protection and attachment scanning to prevent users from clicking on malicious links or downloading harmful files. but on the other hand, Mimecast might be needed, if you require compliance measures, including data loss prevention, archiving, and encryption. It also provides greater visibility and control over email security, allowing you to monitor and manage threats in real-time. Hope this helps.
