Power BI consulting services prioritize data security by implementing best practices like Row-Level Security (RLS) and Azure Active Directory for role-based access control. Consultants configure encrypted connections between Power BI consulting services and data sources. Sensitive data is masked or anonymized before being used in reports. Audit logs and activity monitoring are set up to detect and address unauthorized access. Data governance policies are established for secure sharing and publishing. By adopting robust security measures, consultants ensure that organizational data remains protected while still accessible to authorized users.
