Legal 500

A leading international trade and cybersecurity practitioner, Deen Kaplan is widely recognized for his ability to guide clients through complex multinational legal and technical challenges. Deen represents businesses and governments in some of their most demanding international trade and investment disputes, cybersecurity matters, and cyber policy-related matters. He also serves as a global director of the firm's International Trade and Investment Practice and co-head of Hogan Lovells Cyber Risk Services.

In his trade practice, Deen has guided clients in dispute settlement proceedings before the World Trade Organization (WTO), North American Free Trade Agreement and London Court of International Arbitration panels, U.S. and Chinese government-led investigations and appeals, and trade-related bilateral and multilateral negotiations. Deen's trade-focused areas of concentration include security and trade, government-related disputes, subsidy law policy, WTO matters, and countervailing and antidumping duty litigation.

In his cybersecurity practice, Deen has helped clients navigate some of the world's prominent security incidents, breaches, and security-related matters. Deen regularly manages overall incident responses, threat detection and mitigation strategies, cyber-risk legal assessments and planning, notification obligations, and long-term secure data strategies involving multiple countries and continents. Deen has worked closely with corporate general counsel, dedicated internal and external IT staff, outside security consultants, and law enforcement authorities in North America, Europe, and Asia.
