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.
