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…

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.

Quotes from Members

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

Pros

"It helps reduce spam and phishing attacks."
"The solution is easier to manage than FortiMail. You can implement policies easily."
"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 most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"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 basic features are okay and I'm satisfied with the Defender."
"Since we have started using the solution, there have been fewer compromises."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
 

Cons

"Its pricing could be affordable."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"The UI needs to be more user-friendly."
"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."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"Microsoft Defender for Office 365 should be more proactive."
"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."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"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."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
 

Pricing and Cost Advice

"Email Security Gateway's pricing is good."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The product is expensive."
"The license is expensive because the cost is based on the number of users."
"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 product is very expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
