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 is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"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 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 its spam filter."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"The product is not resource-intensive."
"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

"The product must provide better malware detection."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"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."
"Configuration at the mid-level could be improved for the support team."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"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."
"Microsoft Defender for Office 365 should be more proactive."
"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

"The product is very expensive."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"It's a user-base subscription."
"The license is expensive because the cost is based on the number of users."
"The pricing is normal. Considering its popularity, it's not overpriced."
"The pricing has become expensive."
