More About Daniel
Daniel works with clients across industries on compliance with U.S. and global data protection frameworks, with a growing focus on AI governance and automated decision-making requirements. His practice centers on product and operational counseling, where he advises on privacy and data risk arising from digital product features, workforce data practices, online marketing and tracking technologies, and vendor relationships. He helps clients evaluate regulatory obligations and build compliance programs that work across both internal operations and customer-facing services. This includes advising on the design and documentation of data protection and sharing practices, preparing privacy-related contractual provisions, and counseling on cross-border data transfers involving Europe and Asia.
When security incidents occur, Daniel guides clients through the full mitigation and response lifecycle, from containing threats and restoring business operations to managing breach investigations, regulatory notifications, and stakeholder communications. He also helps clients get ahead of privacy and security risk by developing comprehensive records retention schedules, reviewing and strengthening IT security policies and compliance programs, and establishing defensible data management practices across enterprise IT systems, collaboration platforms, and mobile devices.
Daniel regularly represents and supports businesses in privacy- and technology-related litigation and arbitration matters, including tracking-technology cases and eDiscovery-intensive disputes. His work includes discovery strategy and motion practice, Rule 26(f) planning and negotiations, ESI protocols, protective orders and privilege management, technology-assisted review workflows, proportionality arguments, and coordination with forensic vendors and expert witnesses.
Daniel regularly contributes to Seyfarth publications on privacy, information governance, and emerging technology risk, and has authored pieces for Law360, Westlaw Today, and the firm's Commercial Litigation Outlook.
