Power BI consultants enhance data security by implementing industry-standard security measures, such as Row-Level Security (RLS), role-based access, and data encryption. They configure Power BI consulting to ensure that sensitive information is only accessible to authorized users, reducing the risk of data breaches. By integrating Power BI with secure identity management solutions like Azure Active Directory, consultants ensure that data remains protected at every level of access. This combination of security features allows businesses to confidently use Power BI for reporting and analytics while maintaining compliance with data protection regulations, safeguarding critical business data.
