Featured Reviews

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.
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.
Steve Bowtell - PeerSpot reviewer
Exceptionally easy to integrate and covers a multitude of cybersecurity issues
The solution's interface appears very simple, but it is very complicated in the back end. So, it removes all the complications that an MSP or an MSSP would normally have. The solution's maintenance depends on whether you run it like an MDR platform where you provide the detection response part for the customer. That would normally be the MSP part. Sometimes, you have customers who are just happy to get an email and tell them what the problem is, and they fix it themselves. If there's no in-house expertise, the MSP or the MSSP can do the maintenance. If there's in-house expertise, it's just a matter of advising them. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"The technical support is good and quick to resolve issues."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"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."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"There are several features that I consider valuable."
"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
"The solution is exceptionally easy to integrate and covers a multitude of cybersecurity issues."
 

Cons

"We need to be able to whitelist data at the backend."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"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."
"The XDR dashboard has room for improvement."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"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."
"The solution's security awareness training and phishing are very United States-focused and don't work very well in Australia."
 

Pricing and Cost Advice

"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The product is expensive."
"It's a user-base subscription."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"I was working in the government and it was too expensive for us to use our Microsoft products."
