Tolu Omolaja - PeerSpot reviewer
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.

The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Nur Mohammad - PeerSpot reviewer
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

"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Defender helps us prioritize threats across our organization."
"The product's scalability is good."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"There are several features that I consider valuable."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"Cloudflare is simple to use."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The blocking feature is very good."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare Access is part of the Zero Trust philosophy."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"The email policy configuration options in Microsoft EOP are satisfactory."
"The product protects against malware."
"The initial setup of Microsoft Exchange Online Protection was easy."
"The product's most valuable feature is third-party integrations."
"It has a really nice web-based administration console."
 

Cons

"The pre-sales cost calculations could be more transparent."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"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."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"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."
"The GUI is sometimes slow to fetch the device report and could be improved."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Lacks a VPN feature to provide a secure connection to the data center."
"Operating and tuning the product is difficult."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Our customers no longer use Cloudflare because its service is subpar."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"For the topic of improvement, providing some training material is one of my suggestions."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"The reporting needs a little bit of improvement."
"The tool is not 100% stable."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"Some features, like encryption, are not available."
"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."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
