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.

Dynamic runtime engine and good protection, but needs better support and a single console
We have two to three issues per month. We contact Proofpoint's customer support for these issues. I am a major point of contact for support. If I am not able to resolve an issue, we will be reaching out to them. Proofpoint can take a couple of days to get back. I also deal with other applications from Okta and Microsoft, and we get the support within a couple of hours. There is a lot of difference between a couple of hours and a couple of days. So, Proofpoint's support should be improved. Okta and Microsoft are also able to do a Zoom or video call, but Proofpoint provides support only through email communication. Only if you request, it would be a Zoom or video session.

Quotes from Members

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

Pros

"The initial setup was easy."
"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 most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"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."
"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 most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The technical support is good and quick to resolve issues."
"It has a dynamic runtime engine, which gives it an advantage over Prisma that has a static engine. In Prisma, we have to do additional malware analysis, which is not required in Proofpoint."
 

Cons

"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."
"The XDR dashboard has room for improvement."
"The GUI is sometimes slow to fetch the device report and could be improved."
"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 visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"The product must provide better malware detection."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"We are using the TRAP console that has a Linux-based UI, which is not user-friendly. The TAP console looks very advanced. Currently, we are maintaining three different consoles, and it is sometimes hard to switch between them or try to grab the data."
 

Pricing and Cost Advice

"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."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing has become expensive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"The product is expensive."
"I know that the product is incredibly expensive."
