Enhanced visibility and exposes vulnerabilities but needs more integration

Centralized cloud view has improved threat response and simplified compliance reporting
We are using Trend Vision One - Cloud Security for getting complete visibility of all the assets that exist within our cloud, and it helps us identify any sort of misconfigurations or fine-tuning that can be done to better our compliance. Trend Vision One - Cloud Security helps in onboarding all the cloud solutions or cloud providers that we have within our organization into a single dashboard, thereby providing greater visibility of all the assets. Earlier we used to have multiple dashboards to manage the same solution or capability, but with Trend Micro, we are able to get everything in a single pane of glass, benefiting our operations significantly. We are using the playbooks built into Trend Vision One - Cloud Security, which help us take a lot of response actions and bring automation capabilities into play. Trend Vision One - Cloud Security has positively impacted our organization by providing a single pane of glass visibility across all the cloud solutions that we have and reducing the number of threats we used to see earlier in the cloud. We are seeing that the number of cloud operations required earlier in terms of threat detection and response, and the time taken to detect a particular threat and take a response action, has considerably improved after onboarding Trend Micro.

Quotes from Members

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

Pros

"It seems to be better at protecting from cyberattacks."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"We use the solution to protect our cloud-based applications like Office 365."
"I like the conformity and workload security modules. Workload security is all about intrusion detection and prevention. Trend Vision One - Cloud Security has behavioral rules that are auto-populated based on organizational structure. That's one aspect that we liked most."
"The perfect package for all security platforms, providing more than any other endpoint solution."
"I use the tool for security solutions. It's a leader in Gartner and Forrester Wave reports. Customers rely on these reports."
"The most valuable part of Trend Vision One - Cloud Security is its dashboard, as it's simple. It's easy to manage, and you can better control the solution."
"Virtual patching is one of the key features, which is executed with their IPS."
"The storage and computing features are valuable."
"The tech support is excellent. They really know their products. They also know a lot of about the integrations between different solutions."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
"There are also some loopholes because it's a new product that they have recently migrated to the cloud. We do see some issues with the policies we have assigned when it comes to a particular account. There are some issues with system support, such as a particular server kernel version that is not supported."
"The tool should improve integration with trend products."
"Trend Vision One - Cloud Security could improve connections with different types of authentication and user groups concerning cloud services."
"One area for improvement in Trend Vision One - Cloud Security is marketing; in particular, Trend Vision should update the marketing documentation. The information needs to be more comprehensive."
"The initial setup can be complex for the inexperienced."
"Securing S3 using Trend Vision One - Cloud Security can cost too much. Trend Vision One - Cloud Security has a tool that requires lots of privileges. From my understanding, it's only for static application testing, so they need to add dynamic application testing, and there should be more collaboration with the application testing tools on the market. We have not used this product, and I don't know if they plan to decommission it or something. They should focus on application security because this tool's unique feature is multi-cloud support. However, they should improve integration with tools for these kinds of use cases, especially application security and dynamic scanning. For example, I would like it to support Dell SecureOps. I'd also like to see some enhancements to API gateway security."
"I'd like to see mobile licenses included in the main license, similar to Kaspersky's model for future features."
"Trend Vision One - Cloud Security seems to have a preference for AWS Cloud over Azure and would be improved by focusing equally on both."
