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

"Does a thorough job of examining email and URLs for malicious content."
"Microsoft Defender for Office 365 is a stable solution."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"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."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"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 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."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"There's room for improvement regarding the time frame for retrieving emails."
"The phishing and spam filters could use some improvement."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"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

"I was working in the government and it was too expensive for us to use our Microsoft products."
"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."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"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."
"It's a user-base subscription."
"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."
