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

"Defender for Office 365 has helped eliminate having to look at multiple dashboards and that is the aspect I like most about it. It is simpler, effective, and convenient. The users like the process efficiency."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"The basic features are okay and I'm satisfied with the Defender."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."

"The solution offers good technical support."
 

Cons

"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"There's room for improvement regarding the time frame for retrieving emails."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"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."

"The solution is complex and not easy to use."
"While it's quick and easy, the initial setup could be more user-friendly."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"I'd like to have better support from the product in the future."
 

Pricing and Cost Advice

"The solution saves money so we have seen a return on investment."
"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."
"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."
"I know that the product is incredibly expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"It's a user-base subscription."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
