Cloud Solutions Architect at a tech services company with 201-500 employees
Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Useful for cloud data protection, particularly for email and file-sharing systems
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 solution should also expand integration from the public cloud to the private cloud and add Cloud DLP and CASB features.

Quotes from Members

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

Pros

"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"The email protection is excellent, especially in terms of anti-phishing policies."
"It has helped us in improving our security posture; it detects any kind of attack or abnormal behavior in accessing the system and sends an alert to the administrator who can check, understand, and review on time to ensure that all activities are legit."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"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."
"With Defender for Office 365, we have been able to increase the security posture across our organization."
"The stability of Microsoft Defender for Office 365 is fantastic."
"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."
"Trend Micro has DLP features in it, which separates it from other solutions."
"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."
"Trend Micro Cloud App is easy to use and easy to install."

Cons

"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats."
"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."
"The inbuilt analysis of false positives can be faster. It's not slow, but it can be faster."
"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."
"The phishing and spam filters could use some improvement."
"The cost of Security Copilot is up there right now, and I think it needs to come down for more people to adopt."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"Configuration requires going to a lot of places rather than just accessing one tab."
"They should provide separate corporate-level licenses for two to three instances."
"The price of the solution could improve by being lower."
"The cost of the license is on the high side."
"Documentation could be improved; product cost is quite high."
"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 pricing of this solution is quite high, about double what other similar solutions cost."
"In the next release, I would like to see the cost go down."
"It would be great if Trend Mail Cloud App Security would be joined with a web security solution, making it a multiple-network solution."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It's a user-base subscription."
"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."
"The solution's price is mid-ranged."
"The product's pricing is reasonable compared to other vendors."
"The cost of the license is on the high side. It's a yearly subscription."
"The pricing of the solution could be better."
"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."
