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.

An effective email security solution that provides DLP, Safe Attachment, and Safe Links

If you want extensive email security, you need to purchase a Plan 2 license. Plan 1 and Plan 2 are the two plans for Microsoft Exchange Online Protection. Some customers hesitate to purchase this product because it adds some costs to them, which is necessary for them. It would be helpful for customers if Plan 1 features were included with EOP. However, they still need to purchase Plan 2 for advanced security features. One of our clients recently requested to compare Zimbra's features with Microsoft Exchange Online Protection. Zimbra is open source, while Microsoft Exchange Online Protection is not. When I compare both the products, many free features are available in Zimbra because it is open-source software. It makes no sense to request Microsoft Exchange Online Protection add all the features people get on open-source software like Zimbra. Hence, I would say whatever features Microsoft Exchange Online Protection has are enough. Microsoft has a dedicated research team that should research and add new techniques like phishing and spamming solutions to the product.

"Microsoft Defender for Office 365 is a stable solution."

More Microsoft Defender for Office 365 pros

"You can use the product to create special accounts."

More Microsoft Exchange Online Protection (EOP) pros

"The solution provides protection with its Email Track Records and Machine Manual features."

"With Trend Micro email security gateway, we can deploy features like DLP and BEC."

"The technical support services are excellent."

Cons

"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."

"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."

"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."

"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."

"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 UI needs to be more user-friendly."

"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."

More Microsoft Defender for Office 365 cons

"It would be helpful for customers if Plan 1 features were included with EOP."

"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."

"I think the implementation could be more streamlined."

"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."

"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."

"The solution lacks to elaborate on its spam policies."

"The biggest issue that I experience is that Microsoft keeps moving things around, and it's very inconsistent as to where you find the information when you're trying to work on different pieces."

"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."

More Microsoft Exchange Online Protection (EOP) cons

"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."

"The solution's pricing could be improved."

"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."

"The product's pricing could be more flexible."

Pricing and Cost Advice

"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."

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."

"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
