Vignesh  K - PeerSpot reviewer
Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.
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.

Quotes from Members

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

Pros

"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"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."
"Since we have started using the solution, there have been fewer compromises."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"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."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"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 most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
 

Cons

"The functionalities could be improved, such as the isolation feature."
"Scalability is lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"The GUI is sometimes slow to fetch the device report and could be improved."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"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."
"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."
 

Pricing and Cost Advice

Information not available
"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."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"It's a user-base subscription."
"The license is expensive because the cost is based on the number of users."
"I know that the product is incredibly expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
