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.

Quotes from Members

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

Pros

"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."
"Scalability-wise, I do not think there are any issues so far."
"The stability of Microsoft Defender for Office 365 is fantastic."
"The good part is that you don't have to configure it, which is very convenient."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"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."
"URL scanning and online relay service are the most valuable features of Proofpoint Email Protection."
"The solution is very user-friendly."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"The most valuable features of Proofpoint Email Protection are ease of use, data loss prevention, antivirus, and spam protection."
"I recommend all of my customers to migrate and start using Proofpoint as it is secure, minimizes risk, and eliminates phishing attacks."
"The Phish Alarm button allows users to submit questionable emails for review and complete analysis."
"I would recommend Proofpoint Email Protection to others because it is useful, simple to use, and provides whatever is required."
"Proofpoint is the main tool for blocking spam because it denies the connection altogether."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"I like that it is very user-friendly and easy to install."
"I would rate the solution's stability at ten out of ten."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"I find Trend Micro to be a good solution for security purposes."
"It can effectively monitor outbound and inbound devices."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"Trend Micro is a very good product."
 

Cons

"I'd like some additional features any product can give me to protect our environment in a better way."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"The phishing and spam filters could use some improvement."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Configuration requires going to a lot of places rather than just accessing one tab."
"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."
"Proofpoint Email Protection could improve on the training. Every organization is different and to fine-tune it to block everything properly there needs to be better training. Sometimes it can block some of the information it shouldn't."
"Some use cases haven't been dealt with yet."
"The price could be improved."
"Integration and filtering out who you want and don't want to have integrated ID could be improved."
"The product's deployment is complex and requires technical knowledge."
"The solution could be improved with the addition of PLP and email encryption features."
"The solution should add post-sales training."
"It's scalable, but the devil's in the details — you have to know your email volumes."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."
"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"Trend Micro's technical support has room for improvement."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."
