File-sharing options and ease of collaboration or meetings allow for quick collaborations and chats
I work in my company's IT department, so I use all of the products under Office 365 daily, including Microsoft Word, Microsoft PowerPoint, Microsoft Teams, and all the other components in the product. My company can't make it through a day or go by without using the products offered under Office 365. Some of our manufacturing workers may use Office 365 a lot less, but it is still necessary for things like Microsoft Outlook and Exchange. I found Microsoft Teams to be the most valuable feature of the solution, along with all of the products and features offered under Office 365. My organization has remote workers, and we can't run the company without meetings organized with the help of Microsoft Teams.

Facilitates creation of your own content-filtering policies with relative ease
* Ability to create message bypasses for groups and/or individuals. Meaning, you do not have to "whitelist" email domains or addresses when a specific bypass will do. * Personal Message Manager (PMM): It allows users to release or delete quarantined messages. Also, allows users to add people to a Trusted Senders list. * Ability to create your own content-filtering policies with relative ease.

It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The deployment capability is a great feature."
"The email protection is excellent, especially in terms of anti-phishing policies."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"The good part is that you don't have to configure it, which is very convenient."
"The technical support is good and quick to resolve issues."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"Since we have started using the solution, there have been fewer compromises."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"The integration is straightforward."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"The setup was easy."
"Mimecast certainly helped my customers reduce phishing emails."
"The most valuable feature is the DMARC Analyzer."
"The solution offers good technical support."
 

Cons

"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Configuration requires going to a lot of places rather than just accessing one tab."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"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 solution should include more AI features instead of Mimecast's more general static configuration tooling."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The solution is complex and not easy to use."
"External security features need improvement."
"I'd like to have better support from the product in the future."
 

Pricing and Cost Advice

"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"I know that the product is incredibly expensive."
"The pricing has become expensive."
"The product is expensive."

"It's an expensive solution."
