Notable Representations, Key Contacts
We have an uncompromising commitment to providing practical and actionable guidance. We partner with our clients to develop holistic and tailored strategies to mitigate and address business and legal risks in connection with the privacy and cybersecurity aspects of the full range of corporate transactions (in close partnership with Weil’s Private Equity, M&A and Private Funds practices, and Litigation practice), defending government investigations and other privacy-related proceedings, counseling with respect to compliance with a broad array of jurisdiction- and sector-specific privacy and data security laws, and coordinating urgent first-responder assistance in the event of a breach.
Weil lawyers routinely work with clients in the following areas:

Recognizing that a privacy- or cyber-related development can expand to encompass a number of other significant legal issues, our practitioners work closely with attorneys in our White Collar Defense, Regulatory and Investigations, Securities Litigation, Complex Commercial Litigation, Restructuring and Employment practices, among others, to address all aspects of privacy-related risks.
