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.

Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

Quotes from Members

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

Pros

"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"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."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"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."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"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."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"It is really important for large companies to have the brand protection that is provided by Agari."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"It comes with a lot of helpful tips for complicated areas."
"Trend Micro is a very good product."
"I like that it is very user-friendly and easy to install."
"It can effectively monitor outbound and inbound devices."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"I would rate the solution's stability at ten out of ten."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"I find Trend Micro to be a good solution for security purposes."
 

Cons

"There is room for improvement in terms of reporting."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"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 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."
"We need a separate license and we don't know how to get the license that is required."
"We need to be able to whitelist data at the backend."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"The custom alerts have to improve a lot."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"Trend Micro's technical support has room for improvement."
"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."
"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."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."

"The price of the licensing is based on the volume of email."
