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.

Handles security, malware and spam of email systems
We use Email Security Gateway on email systems for handling security, malware, and spam.  The solution is easier to manage than FortiMail. You can implement policies easily.  The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very…

Easy to deploy and user-friendly with simple dashboards
I'm also using Microsoft Defender. We've also used Proofpoint. Proofpoint has more granularity. It also offers different features. Exchange Online and Defender offer safe attachments and anti-malware. However, they just have one single option for features, and you check a box, and it enables one blanket policy. With Proofpoint, you can choose your options. Microsoft products are good and more user-friendly in general. They are just missing the granularity aspect. In Proofpoint, the tap and trap work very well, and it has some kind of monitoring as well for the tap and trap. When you're moving from Proofpoint to Microsoft, if you need to do a comparison and if you need to showcase to the customer all features are working as expected, some functionalities might be a little difficult for us to showcase. Maybe that dashboard will differ. It's a common dashboard that we have for Microsoft. Maybe Proofpoint has got more features, however, for use cases, it'll be a little difficult to demonstrate to the customer. We've moved to this solution since we were moving the majority of our products to Azure. We wanted to move to the cloud to reduce hardware costs and avoid having a separate server, which we do not need for Exchange.

Quotes from Members

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

Pros

"The deployment capability is a great feature."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The initial setup was easy."
"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."
"The ability to respond to threats if very important."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."

"It is an easy solution."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"You can use the product to create special accounts."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
 

Cons

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"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."
"The pre-sales cost calculations could be more transparent."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"There is a different console for different things; I just want one consolidated console."
"The custom alerts have to improve a lot."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"Its pricing could be affordable."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"The solution must improve the user experience."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
