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."
"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."
"The deployment capability is a great feature."
"The DLP feature of Microsoft Defender for Office 365 is valuable, and we also use the DLP feature for email real-time detection."
"Does a thorough job of examining email and URLs for malicious content."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"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 initial setup is pretty straightforward."
"Trend Micro Cloud App is easy to use and easy to install."
"Dependable with ease of integration with other security products."
"It has more intelligence features than other vendors."
"The most valuable feature of Trend Micro Cloud App Security is its stability across all platforms."
"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 solution is easy to integrate."
"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."
 

Cons

"The custom alerts have to improve a lot."
"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."
"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."
"You should be able to deploy Defender for every subscription without the need to add servers."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"They should provide separate corporate-level licenses for two to three instances."
"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."
"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."
"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
"The granulation of the policy setup needs to be better. Right now, it is too basic."
"The price of the solution could improve by being lower."
 

Pricing and Cost Advice

"The license is expensive because the cost is based on the number of users."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"I know that the product is incredibly expensive."
"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."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The product is expensive."
"It's a user-base subscription."
"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."
"The cost of the license is on the high side. It's a yearly subscription."
"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 pricing of the solution could be better."
"The solution's price is mid-ranged."
"The product's pricing is reasonable compared to other vendors."
