Lindsey Tonsager is a recognized leader in representing companies before federal and state regulators, and is renowned for advising on minor protection, AI, and state comprehensive privacy laws.

Lindsey chairs the firm’s global Data Privacy and Cybersecurity practice. She advises clients in their strategic and proactive engagement with the Federal Trade Commission, the U.S. Congress, the California Privacy Protection Agency, and State Attorneys General on proposed changes to data protection laws, and regularly represents clients in responding to investigations and enforcement actions involving their privacy and information security practices.

Lindsey’s practice focuses on helping clients launch new products and services that implicate the laws governing the use of artificial intelligence; data processing for robotics, autonomous vehicles, and other connected devices; biometrics; online advertising; the collection of personal information from children, teens, and students online; e-mail marketing; disclosures of video viewing information; and new technologies.

Lindsey also assesses privacy and data security risks in complex corporate transactions where personal data is a critical asset or data processing risks are otherwise material. In light of a dynamic regulatory environment where new state, federal, and international data protection laws are always on the horizon and enforcement priorities are shifting, she focuses on designing risk-based global privacy programs for clients that can keep pace with evolving legal requirements and efficiently leverage the clients’ existing privacy policies and practices. She conducts data protection assessments to benchmark against legal requirements and industry trends and proposes practical risk mitigation measures.
