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.

Creates robust rules for communication and data security, boosting compliance measures
I was talking with some engineer from Microsoft about how we can audit our web page. They create or add to Microsoft Purview Communication Compliance that part, the Layer seven of the OSI model, to check the application and maintain a good practice of coding. I've tried the web page part, and it works great. However, monitoring and compliance for web applications could be improved.

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."
"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."
"The good part is that you don't have to configure it, which is very convenient."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The product's scalability is good."
"Scalability-wise, I do not think there are any issues so far."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
"Customer support is excellent."
"The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind."
"The time it saves is very useful."
 

Cons

"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"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."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Configuration requires going to a lot of places rather than just accessing one tab."
"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 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."
"The XDR dashboard has room for improvement."
"Monitoring and compliance for web applications could be improved."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"The product should incorporate more automation with the help of AI."
 

Pricing and Cost Advice

"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."
"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."

"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The pricing has become expensive."
"The product is very expensive."
"The product is expensive."
"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."
