Michelle Kisloff is a proven litigator and advocate who helps her clients succeed when complex matters of data privacy and protection result in litigation and regulatory enforcement.

She has assisted organizations in responding to some of the largest data breaches and state-sponsored cyber attacks on record – and in defending against the internal investigations, class action litigation, Congressional inquiries, and regulatory enforcement actions that follow these events. She has also handled dozens of other inquiries into data use and breaches that have not resulted in a public record because, after investigation, the clients decided not to make a public notice.

Michelle also defends and advises organizations accused of violating consumer privacy or misusing consumer data. She has successfully resolved investigations by the Federal Trade Commission and various state attorneys general (most often with non-public closures) and won early dismissals of proposed class actions related to data collection and alleged consumer tracking.

Michelle advises clients and speaks frequently on developing data privacy and security programs, complying with consent decrees arising from privacy-related enforcement actions, planning for data security events, and in evaluating cyber-insurance coverage. Her clients view her as a problem-solver focused on finding practical and workable legal resolutions.

For more than 20 years, Michelle has successfully litigated a broad spectrum of commercial disputes, ranging from insurance coverage disputes and complicated indemnification questions to antitrust claims, post-merger disputes over deal disclosures and terms, and franchise arrangements.

Before joining Hogan Lovells, Michelle clerked for a federal district court judge in Pennsylvania and also worked for another law firm in New York City. Michelle volunteers her time as a member of the board of directors of My Sister's Place, which provides housing and support to women and children fleeing domestic violence in Washington, D.C.
