Our Global Investigations & White Collar Defense team represents corporations, boards of directors, board committees, public officials and executives in criminal, civil and regulatory enforcement proceedings worldwide.

Mayer Brown’s practice includes a diverse team of former federal prosecutors and government enforcement lawyers who know firsthand how government enforcement works and how to respond to the challenges and risks posed by criminal investigations and civil enforcement proceedings. We work closely with clients to ensure compliance with an ever-changing, increasingly global regulatory framework and to respond to investigations by regulators throughout the world. And when matters go to trial, we’re ready for that, too; we have collectively tried hundreds of federal criminal cases, both as defense counsel and as former prosecutors.


We represent clients across the most highly regulated industries—such as health care, defense, automotive, gaming, energy, technology and the global financial services sector—on the full range of matters for which companies and executives can be held accountable. These include:
