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.

Pros

"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."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"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."
"Scalability-wise, I do not think there are any issues so far."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"Microsoft Defender for Office 365 saves me time; it does save a lot of time, especially with the automation."
"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."
"Dependable with ease of integration with other security products."
"Trend Micro Cloud App is easy to use and easy to install."

Cons

"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."
"From a development point of view, if I wanted to do development on my actual machine where Defender is, the organization can set certain policies or Defender makes that prohibitive."
"The pre-sales cost calculations could be more transparent."
"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."
"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."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"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."
"It would be great if Trend Mail Cloud App Security would be joined with a web security solution, making it a multiple-network solution."
"They should provide separate corporate-level licenses for two to three instances."
"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 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."

"There is room for improvement in the DLP component of Trend Micro Cloud App Security."
