Céline M. Guillou

Céline Guillou’s practice focuses on data privacy law and compliance, with a particular focus on U.S. and European data protection laws and California consumer privacy laws. Céline is a member of Hopkins & Carley’s Corporate Practice in the Palo Alto office.

Céline advises companies on how to proactively and strategically manage their data privacy and security risks across multiple teams and stakeholders. She develops and implements information privacy and security compliance programs for her clients, and her day-to-day practice includes assessing applicable data protection laws and risks, developing internal and consumer-facing policies and notices, drafting and reviewing third-party data protection agreements and developing overall data protection strategies and processes within client organizations. Her practice also includes data breach management/reporting, and, as a former commercial litigator, she advises on information security litigation and regulator enforcement. Because personal information is a valuable asset for so many companies, she also assists the firm’s M&A team in addressing data protection in their transactions.

Céline advises private and public company clients in a wide range of industries, including gaming, property management, B2B, e-commerce, Saas, IoT, and hospitality. She holds a (CIPP/E) certification from the International Association of Privacy Professionals (IAPP), the global standard in privacy certification.
