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.

Helps to manage and implement DMARC for clients
The product helps me manage and implement DMARC for my clients. It makes the process easy, which is otherwise complicated.  The tool's most valuable features are hosted SPF and DMARC records.  EasyDMARC should improve white labeling.  I have been using the product for a year.  I rate the…

"The technical support is good and quick to resolve issues."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."

"The solution's most valuable feature is its simplicity. It's very user-friendly."

Cons

"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"The UI needs to be more user-friendly."

"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."

"Sometimes especially zero-day spam emails can be passed to the user's inbox."
"I would rate them as a 1.5. The new hub created in India is not good."
 

Pricing and Cost Advice

"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."
"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."

"The cost is very high."
