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

"The initial setup was easy."
"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."
"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The product's scalability is good."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"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 is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"Dependable with ease of integration with other security products."
"The most valuable feature of Trend Micro Cloud App Security is its stability across all platforms."
"I find Trend Micro Cloud App Security useful for scanning our email boxes. We can scan them one by one, which is a good feature. It's not just gateway-level protection - we integrate the email system with it. They have special protection and parameters for phishing emails."
"Trend Micro has DLP features in it, which separates it from other solutions."
"The solution is easy to integrate."
"It has more intelligence features than other vendors."
"Trend Micro Cloud App is easy to use and easy to install."
"Our business emails are very important and Trend Micro Cloud App Security has provided a high level of protection. Additionally, there are updating the solution frequently."
 

Cons

"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 UI needs to be more user-friendly."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"Configuration at the mid-level could be improved for the support team."
"Configuration requires going to a lot of places rather than just accessing one tab."
"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."
"Documentation could be improved; product cost is quite high."
"It would be great if Trend Mail Cloud App Security would be joined with a web security solution, making it a multiple-network solution."
"The granulation of the policy setup needs to be better. Right now, it is too basic."
"The solution's technical support services could be better."
"They should provide separate corporate-level licenses for two to three instances."
"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
"For improvements, I think it would be great if Trend Micro Cloud App Security could enhance their product to be a single SASE solution. It should be similar to competitors like Palo Alto."
"The price of the solution could improve by being lower."
