Gus P. Coldebella, a member of the National Law Journal’s inaugural class of “Cybersecurity Trailblazers” in 2015, is a principal in the Commercial Litigation Group in Fish’s Boston and Washington, D.C. offices.  His practice involves helping companies deal with all aspects of cybersecurity incident response and planning, government and internal investigations, complex civil litigation, and management of crises of all types.​

Mr. Coldebella was the U.S. Department of Homeland Security’s acting General Counsel from February 2007 to January 2009, and its Deputy General Counsel from October 2005 to February 2007, focusing on all major homeland security issues confronting the Department and the nation. He is a recognized authority on the legal and policy aspects of homeland and cyber security.  At DHS, he helped lead implementation of President Bush’s Comprehensive National Cybersecurity Initiative, designed to shore up the government’s civilian networks from attack and to promote cooperation between the public and private sectors.  In private practice, he helps clients investigate and manage all aspects of cyber security incidents.  He advises companies and their boards of directors on steps that can be taken to mitigate the risk of attack, as well as post-event regulatory enforcement and litigation.  His experience as a securities litigator perfectly positions him to advise public companies on SEC and other regulatory requirements regarding cyber security disclosures and board of directors’ fiduciary duties regarding the same.  Coldebella also advises on other security related issues, including privacy, infrastructure protection, liability protection, and export control.

Coldebella’s litigation practice also includes securities and M&A litigation, partnership and post-closing disputes, breach of fiduciary duty cases, class actions, and other complex litigation.  He conducts internal investigations, including those arising out of whistleblower complaints or shareholder derivative demands, involving fiduciary duties, corporate governance, insider trading, compensation, export control, government contracting, anti-corruption, U.S. GAAP compliance, public disclosure, and the like.  He represents clients in all manner of governmental investigations and agency enforcement actions by federal and state agencies including SEC, FBI/DOJ, DHS, FTC, OFAC/BIS, agency inspectors general and others, and manages congressional investigations and testimony.
