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

"It has significantly decreased my time to detection and response."
"Does a thorough job of examining email and URLs for malicious content."
"There are several features that I consider valuable."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"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."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"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 most valuable feature of Trend Micro Cloud App Security is its stability across all platforms."
"The solution is easy to integrate."
"Dependable with ease of integration with other security products."
"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."
"It has more intelligence features than other vendors."
"Trend Micro has DLP features in it, which separates it from other solutions."
"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."
"The initial setup is pretty straightforward."
 

Cons

"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"We need to be able to whitelist data at the backend."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Microsoft Defender for Office 365 should be more proactive."
"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."
"Documentation could be improved; product cost is quite high."
"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
"The price of the solution could improve by being lower."
"It would be great if Trend Mail Cloud App Security would be joined with a web security solution, making it a multiple-network solution."
"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."
"In the next release, I would like to see the cost go down."
"The solution's technical support services could be better."
"They should provide separate corporate-level licenses for two to three instances."
 

Pricing and Cost Advice

"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The product is expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The price of Trend Micro Cloud App Security is expensive for regular users. There are not any hidden fees. First-time users of the solution should purchase implementation packages or professional services."
"The cost of the license is on the high side. It's a yearly subscription."
"The solution's price is mid-ranged."
"The product's pricing is reasonable compared to other vendors."
"The pricing of the solution could be better."
