Allows for easy reporting of problems, valuable anti-phishing, and anti-malware support
Microsoft Defender for Office 365 lacks proactivity in assisting us with preparing for potential threats before they occur. While they employ a substantial amount of threat intelligence to preemptively prevent incidents, their effectiveness diminishes when it comes to delivering proactive threat intelligence alerts from Microsoft. Their focus primarily revolves around managing the internal environment. On the other hand, my other vendor, Check Point, along with my membership in MS-ISAC, supplements me with this type of information. The phishing and spam filters could use some improvement. It is adequate, but it doesn't match the quality of Proofpoint or Mimecast. However, it comes close in effectiveness. Plus, if we're obtaining it for free, investing in the other products seems impractical.

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…

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 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."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The product's scalability is good."
"Does a thorough job of examining email and URLs for malicious content."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"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."
"There are several features that I consider valuable."
"The basic features are okay and I'm satisfied with the Defender."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"The product is good. To date, we have not faced any challenges."
"The setup was easy."
"The solution's performance is good."
 

Cons

"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."
"The pre-sales cost calculations could be more transparent."
"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."
"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."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"We need to be able to whitelist data at the backend."
"I'd like some additional features any product can give me to protect our environment in a better way."
"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."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"The installation is not so straightforward."
"The attachment scanning feature doesn't work properly."
"The tool can be challenging because it relies on rule-based configurations, especially for addressing impersonation threats. This approach requires setting up numerous rules to ensure filtering. It should work based on behavior-based analytics."
"The platform's cost-effectiveness could be improved."
"The solution is complex and not easy to use."
"While it's quick and easy, the initial setup could be more user-friendly."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
 

Pricing and Cost Advice

"The solution saves money so we have seen a return on investment."
"It's a user-base subscription."
"The license is expensive because the cost is based on the number of users."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The pricing is normal. Considering its popularity, it's not overpriced."
