  • Events: Zluri curates any news related to the app’s security whenever it is in use from the internet and shows it in the Events Tab. E.g., Ransomware, data breaches, any patch, or security loopholes.

    The risk score of each app is determined by analyzing the number of events. For instance, the higher the number of events, the lower the risk score the app will have.

  • Data Shared: When you connect an app with other apps, then these apps will have access to the content of the connected app. The apps can have different types of access: read, write, modify, and delete access. The more sensitive data the app can access, the higher the threat level will be.

    For example, if an app can access Google Drive and modify or delete drive files, it is given a high threat level.

  • Compliance: Zluri gives compliance information for each app showing which compliance frameworks the app complies with. The higher the number of frameworks the app complies with, the higher the risk score will be.
