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

"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."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"Defender helps us prioritize threats across our organization."
"The email protection is excellent, especially in terms of anti-phishing policies."
"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 most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"It stops in excess of twenty-five malware events per month, all of which could be critical to the business."
"Provides good exfiltration, and is an all-in-one product."
"It is stable and reliable."
"It is very scalable."
"The most valuable features are the administration console and its detection and response module."
"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."
"I recommend this solution because of its ease of use."
 

Cons

"The custom alerts have to improve a lot."
"The phishing and spam filters could use some improvement."
"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 Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"The XDR dashboard has room for improvement."
"The pre-sales cost calculations could be more transparent."
"We need a separate license and we don't know how to get the license that is required."
"There could be a tool that automatically updates all-new Microsoft IPs, which are available for free to connect to the client."
"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."
"I would like to see future versions of the solution incorporate artificial intelligence technology."
"This solution needs to be made "cloud ready"."
"We'd like them to be better at dealing with script threats."
"The initial setup was industry standard complex. It takes awhile and has a lot of planning involved. It could be simplified with product redesign."
"Lacks remote capabilities not dependent on the internet."
 

Pricing and Cost Advice

"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"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 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."
"The product is very expensive."
"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."
"The product is expensive."
"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."
