She leads the firm's Data, Privacy & Security Practice and regularly counsels corporate boards, senior executives and other clients on data breach prevention, emergency response, remediation, compliance, regulatory enforcement and internal investigations. She is a crisis manager and trial lawyer, who works with her clients' legal, compliance and business teams to strategize, manage and defend when significant privacy and security issues arise. She currently represents clients who are defending against class actions, regulator investigations and Congressional inquiries as the result of data security incidents, including defending Equifax in the 2017 data breach involving the Social Security numbers of approximately 145.5 million consumers.
