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.

Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.

Quotes from Members

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

Pros

"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."
"Defender helps us prioritize threats across our organization."
"The product's scalability is good."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The technical support is good and quick to resolve issues."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"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."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
"The setup was easy."
"Proofpoint Email Protection's advantage is that, when it's working properly, it tends to catch more threats as compared to other products."
"The solution has very strong detection for most of the phishing and malicious emails received from the outside."
"It was easy to set up."
"The solution scales well."
"It's the top choice because no company can operate without security. Ensuring email protection is a major priority for any organization when building its infrastructure."
"They have customized security rules, mature rules, anti-virus protection, as well as email authentication similar to SPF, DKIM, and DMARC."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
 

Cons

"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"We need a separate license and we don't know how to get the license that is required."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"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."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"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 product must provide better malware detection."
"The UI needs to be more user-friendly."
"The functionalities could be improved, such as the isolation feature."
"Scalability is lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong."
"Sometimes it doesn't detect actual spam emails, and sometimes it catches normal emails."
"The initial setup is complex."
"We find the cost to be prohibitive."
"They do not have an on-demand scan for the internal viruses and internal users, and they don't have a scan for the exchange server against viruses and spam as Symantec does."
"The solution's server console and cluster dashboard have been the same for four years so need to be upgraded."
"The solution could lower its price."
"You only receive one model in Proofpoint Email Protection and the other ones you have to purchase at a high price. There should be more available with the solution and additional models should be less expensive."
"It has too many screens. It is kind of a conglomeration of products. In other words, they built product A, product B, and product C, and they are yet to integrate them into a single administrative console. I would certainly like to see a more seamless administrative interface. I would also like to see them include more bang for the buck, by including features like email fraud protection, rather than making their product so piecemeal, where you are buying little pieces. I agree with the idea of having multiple tiers or layers, but maybe as small, medium, and large, as opposed to an a la carte menu."
 

Pricing and Cost Advice

"The pricing has become expensive."
"The product is very expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
