Biography

Daniel B. Rosenzweig is a Data Privacy, AI, and Cybersecurity attorney. He advises clients on legal and technical compliance with data privacy and AI laws, including the CCPA/CPRA, CO AI Act, and other state privacy and AI laws, CAN-SPAM Act, COPPA, ePrivacy Directive, GDPR, EU AI Act, FTC Act, GLBA, HIPAA, TCPA, and VPPA. He also counsels clients on industry mobile app store requirements, AdTech, and privacy-enhancing technologies (PETs).

 

Daniel’s legal practice is unique in that he develops technical solutions to enhance his legal services, often serving as a bridge between legal, marketing, and technical teams. He excels at helping legal, development, and product teams put the law into action by translating complex legal requirements into actionable technical implementations.

 

He developed a technical solution that evaluates consumer-facing websites and mobile apps, generating reports on data collected and disclosed to help companies assess privacy risks and implement appropriate mitigations. He also developed tools to detect and validate the effectiveness of consumer preference signals (e.g., opt-outs and consent flows), identify and mitigate VPPA and wiretap (e.g., session replay) exposure, and leverage AI to conduct legal research across various state data privacy laws and regulations.

 

Daniel assists clients across many different sectors, including, among others: media, retail, telecommunications, healthcare, sports, financial services, hospitality, and tech. With Daniel’s legal and technical knowledge, he translates complex legal and technical concepts into digestible action items for an organisation’s legal, development, and marketing teams.

 

Daniel advises clients on the building and implementing legal and technical data privacy and AI compliance programs across all stages of the development lifecycle, including:

  • Drafting applicable disclosures, privacy policies, operational controls, consent flows, opt-outs, data privacy portals/webforms, and contracts;
    performing technical testing and validation of data protection/privacy preference signals (e.g., GPC) and controls across websites, mobile apps, and IoT devices;
  • Advising on Data Subject Requests (“DSRs”) and Verifiable Consumer Requests;
  • Conducting data mapping exercises and risk assessments, including Privacy Impact Assessments (PIAs) and Data Protection Impact Assessments (DPIAs); and
  • Assisting clients with onboarding vendors and new technologies, including AI, Large Language Models (LLMs), and more.

 

Daniel also focuses on matters related to advertising, marketing, autonomous and connected vehicles, and regulatory investigations.

 

Before establishing DBR Tech Law, Daniel carved his reputation as a seasoned attorney at an international AM Law 20 law firm. While attending the Georgetown University Law Center, he served as a law clerk at the United States Senate Committee on Homeland Security and Governmental Affairs, where he worked on homeland security and cybersecurity issues. He was also a Legal Intern in FTC Commissioner Julie Brill’s office, focusing on online privacy, data security, and consumer protection law. He’s regularly invited to speak at professional conferences, contribute to industry articles, and appear on relevant podcasts.
