"The email protection is excellent, especially in terms of anti-phishing policies."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"The initial setup was easy."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"Defender helps us prioritize threats across our organization."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"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."
"The solution is pretty straightforward to use and easy to set up."
"The product is good. To date, we have not faced any challenges."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"It's good, it keeps the spam out."
"The most valuable feature is the DMARC Analyzer."
"The initial setup is very straightforward."
"The XDR dashboard has room for improvement."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"There's room for improvement regarding the time frame for retrieving emails."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The solution is complex and not easy to use."
"Its pricing can be improved. It is a bit expensive."
"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."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"The detection rates are an area for improvement."
"The solution is very expensive."
"They could provide a unified licensing model, including all the security features."

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.
