The webinar presented by TrustArc and Privya focuses on the importance of data inventories for regulatory compliance, risk management, and strategic planning amidst increasingly complex privacy laws. It emphasized the challenges of manual data inventory creation and the benefits of automation and code-based data discovery strategies, particularly those offered by partnering companies. The integration of TrustArc's data inventory hub with Privya's AI-driven data discovery tools aims to streamline inventory management, enhance compliance, and mitigate risks associated with third-party data sharing.
