Tolu Omolaja - PeerSpot reviewer
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.

Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.
Frank Rawson - PeerSpot reviewer
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 stability of Microsoft Defender for Office 365 is fantastic."
"The deployment capability is a great feature."
"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."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The email protection is excellent, especially in terms of anti-phishing policies."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"They are very easy to use."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"The initial setup is very straightforward."
"It's good, it keeps the spam out."
"It offers an easy initial setup."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"The setup was easy."
"The integration is straightforward."
 

Cons

"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."
"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."
"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."
"The GUI is sometimes slow to fetch the device report and could be improved."
"You should be able to deploy Defender for every subscription without the need to add servers."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"Configuration at the mid-level could be improved for the support team."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Email security checks contain a small number of false positives."
"The detection rates are an area for improvement."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The feature that should be included is to remove the block on the encrypted files."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The attachment scanning feature doesn't work properly."
"As a user, the user interface of the management console could be upgraded, for example."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"They should improve the cookies management feature."
 

Pricing and Cost Advice

"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"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."
"I know that the product is incredibly expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."
"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
"The licensing costs are per-user for the product that you get with them."
"The product price is moderate. I rate the pricing a five out of ten."
"The product has good pricing in terms of return on investment."
"The solution is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The customers can select the license packages as per their requirements."
"We pay monthly fees to our provider."
"It's an expensive solution."
