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.

Easy to set up and use with a nice interface
The scalability could be better. We'd like them to be better at dealing with script threats. In sandboxing, the time to respond is slower than we would like. We'd like them to be able to process faster. For example, Fortinet, they are doing 18,000 files per hour. For Wildfire, it is elastic. It can support as many files as you get. McAfee doesn't react like that. It does not support interfaces with HTTPS.

Quotes from Members

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

Pros

"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The initial setup was easy."
"Defender helps us prioritize threats across our organization."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"It is stable and reliable."
"It is very scalable."
"Provides good exfiltration, and is an all-in-one product."
"I recommend this solution because of its ease of use."
"Its greatest strength is the DXL client which can rapidly disseminate attack information to all clients via the McAfee Agent instead of going through the ePO server."
"It stops in excess of twenty-five malware events per month, all of which could be critical to the business."
"The most valuable features are the administration console and its detection and response module."
 

Cons

"We need to be able to whitelist data at the backend."
"We need a separate license and we don't know how to get the license that is required."
"There's room for improvement regarding the time frame for retrieving emails."
"The XDR dashboard has room for improvement."
"Several simulation options are available within 365, and the phishing simulation could be better."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"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."
"There is room for improvement in terms of reporting."
"There could be a tool that automatically updates all-new Microsoft IPs, which are available for free to connect to the client."
"We'd like them to be better at dealing with script threats."
"I would like to see future versions of the solution incorporate artificial intelligence technology."
"The initial setup was industry standard complex. It takes awhile and has a lot of planning involved. It could be simplified with product redesign."
"This solution needs to be made "cloud ready"."
"Lacks remote capabilities not dependent on the internet."
"Make the ATD system a part of the whole product and take the whole thing onto the cloud. While it is there already, it is not to the same level as the on-premise version."
 

Pricing and Cost Advice

"It's a user-base subscription."
"The product is very expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"I know that the product is incredibly 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."
"The license is expensive because the cost is based on the number of users."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The product is expensive, but it is better than the rest of them in the industry."
"Our licensing fees for this solution are approximately one million dollars per year."
