What steps have you taken to ensure data security and privacy of my information in Lexis+ AI?
Protégé is designed with robust privacy and security measures in place to protect sensitive client information and ensure compliance with relevant data protection regulations. Users can review and manage their personalization settings at any time, allowing them to adjust the level of personalization or opt out entirely if desired. Furthermore, the data they share is not used to inform performance for other users. By putting the user in control and providing transparency around data access and personalization settings, Protégé aims to strike a balance between leveraging the power of AI personalization to enhance legal services and maintaining the highest standards of privacy, security, and user autonomy.
LexisNexis has always emphasized two critical AI development tenets: users are in control of personalization, and data they share is not used to inform performance for other users. With the Protégé, customers decide which personalization services are enabled and whether personal work product is used to answer questions or draft documents. LexisNexis remains committed to providing the most secure and confidential AI experience for lawyers and with new capabilities to unlock a more personalized AI experience.
Finally, LexisNexis has a comprehensive data protection program to safeguard customer information, including encryption, compliance with data protection laws, and regular security assessments and audits.
