How Cloud App Security helps protect your Dropbox environment

Applies to: Microsoft Cloud App Security

As a cloud file storage and collaboration tool, Dropbox enables your users to share their documents across your organization and partners in a streamlined and efficient way. Using Dropbox may expose your sensitive data not only internally, but also to external collaborators, or even worse make it publicly available via a shared link. Such incidents can be caused by malicious actors, or by unaware employees.

Connecting Dropbox to Cloud App Security gives you improved insights into your users’ activities, provide threat detection using machine learning based anomaly detections, information protection detections such as detecting external information sharing, and enabling automated remediation controls.

Main threats

  • Compromised accounts and insider threats
  • Data leakage
  • Insufficient security awareness
  • Malware
  • Ransomware
  • Unmanaged bring your own device (BYOD)

How Cloud App Security helps to protect your environment
