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…

Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Quotes from Members

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

Pros

"The tool's most valuable features are hosted SPF and DMARC records."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"It has significantly decreased my time to detection and response."
"The good part is that you don't have to configure it, which is very convenient."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"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 gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"The features I appreciate most about Microsoft Defender for Office 365 are admin notifications for potential threats along with protecting our Microsoft apps such as Outlook from potential phishing attacks."
 

Cons

"EasyDMARC should improve white labeling."
"The product must provide better malware detection."
"We need to be able to whitelist data at the backend."
"The GUI is sometimes slow to fetch the device report and could be improved."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"To improve Microsoft Defender for Office 365, it would be nice to have more accessibility for users to see on their end what they are doing that could cause a threat."
"The custom alerts have to improve a lot."
"The phishing and spam filters could use some improvement."
