- Data Storage Security: Power BI has two main repositories for storing and managing data: Azure Blob Storage, and Azure SQL Database. A gateway role (handled by Azure API Management) manages all the user roles and authentications.
- User Authentication: Power BI uses Azure Active Directory (AAD) to authenticate users who sign in to the Power BI service, and in turn, uses the Power BI login credentials whenever a user attempts to access resources that require authentication.
- Data and Service Security: As mentioned above, data and service security in Power BI is managed by AAD and it covers Security, privacy and compliance.
- Enforcing TLS version usage: Network and IT administrators can enforce the requirement to use current TLS (Transport Layer Security) for any secured communication on their network.
According to the factors discussed in this article, we can agree that both Power BI and Looker are capable business intelligence tools that offer various features including data modeling and predictive analytics.
