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.

Can quickly identify, track, tag, and categorize internal emails. Reporting accessibly via the main dashboard would be a great addition.
If Cisco could continue to develop integrations, whether it's internal tooling, Threat Grid, or AMP reporting which could be accessible via a single web page, that would be helpful. This would essentially add additional context on messages as well as files or links being detected. Potentially adding additional context on why certain messages are tagged as spam or malware. In our case, malware hasn't been detected yet, but spam certainly has been. Knowing what engines or which components of the message make it identifiable as spam, that could be useful. Additional context and reporting accessibly via the main dashboard would be great. There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting.

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.

Quotes from Members

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

Pros

"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"Defender helps us prioritize threats across our organization."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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."
"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."
"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."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"Secure Email Threat Defense's scalability is good."
"It's very easy to deploy and configure."
"It has an efficient email filtering feature."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"The solution is stable."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"The initial setup was easy. The configuration process is very straightforward."
"I like the product's ZAP feature."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"It is an easy solution."
"The security features provided by Microsoft are robust."
"The threat management feature includes policies and alerts that are valuable."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities. Additionally, the solution is easy to use."
 

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."
"The XDR dashboard has room for improvement."
"There is room for improvement in terms of reporting."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"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."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"The solution is a bit expensive."
"This solution could be improved by integration with Sandbox."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"The pricing could always be better."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"It would be helpful for customers if Plan 1 features were included with EOP."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"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."
"The solution lacks to elaborate on its spam policies."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
 

Pricing and Cost Advice

"The pricing is normal. Considering its popularity, it's not overpriced."
"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 is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"The license is expensive because the cost is based on the number of users."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The feedback from vendors and customer is that it is expensive."
"It's a high price."
"It is a low-price solution."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"The price of Microsoft Exchange Online Protection is reasonable."
"The price could be lower."
"Online Protection is fairly expensive."
"The solution is expensive but is backed by Microsoft's reputation."
"The solution is priced high and could be less expensive compared to other solutions."
