Daniel B. Rosenzweig


Founder & Principal Attorney


Daniel B. Rosenzweig is a Data Protection, Privacy, and Cybersecurity attorney. He advises clients on legal and technical compliance with data protection and privacy laws, including the CCPA/CPRA and other state privacy laws, CAN-SPAM Act, COPPA, ePrivacy Directive, GDPR, FTC Act, GLBA, HIPAA, TCPA, and VPPA, and counsels them on Artificial Intelligence (AI) and Large Language Models (LLMs) matters, industry mobile app store requirements, and the use of AdTech and privacy-enhancing technologies (PETs).

Daniel’s legal practice is unique in that he also develops technical solutions to enhance his legal services. He developed a technical solution that evaluates consumer-facing websites and mobile apps and generates reports of data collected and disclosed, enabling companies to assess data privacy risk and implement appropriate mitigations. He has also developed solutions that 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 use AI to conduct legal research across the 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 organization’s legal, development, and marketing teams.


Daniel advises clients on the building and implementation of legal and technical data protection/privacy 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. 

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

Before establishing DBR Data Privacy Solutions, 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.

Beyond his legal commitments, Daniel devotes time to Big Brothers Big Sisters, where he mentors as a committed “Big Brother.”
