Representing clients in all aspects and stages of white collar, corporate compliance, investigations and enforcement work, Brown Rudnick works diligently to minimize the consequences of investigations and enforcement actions.

Brown Rudnick is a law firm designed for speed and performance. In an age of whistleblowers, tip lines, and the 24-hour news cycle, more people than ever are minding your business. Brown Rudnick’s White Collar Defense & Government Investigations group has the experience, depth and judgment to provide that response. With lawyers in the US and UK, our team employs an integrated, global approach in crafting comprehensive solutions. Our lawyers include former prosecutors and regulatory officials in the key global jurisdictions of today’s enforcement environment, and together have decades of experience in the highest-profile criminal and regulatory matters. When potential issues arise, we have the experience to drive the investigation, get ahead of the issue, and avert or manage any crisis.

If you learn of allegations of fraud, crime or regulatory violations, you need the right advice - early. As a result of our practical experience and genuine understanding of how regulators and enforcement agencies work, we will be able to swiftly identify whether a matter requires action. We can assist you in assessing the risk of shareholder or personal action being taken if no investigation is undertaken and can also help calibrate the risk of a potential whistleblower, disgruntled employee or competitor taking matters out of your hands.

If an internal investigation is required, we will conduct it in a proportionate manner and in line with agreed objectives and outcomes. We have substantial insight into the breadth and depth of information that investigative agencies will likely require. We use that insight in refining the range of issues from the earliest stage and placing our focus on the crux of the matter.

We avoid “mission creep” by working proactively toward the desired goal. We report regularly to you and apply controlled processes to each phase of an investigation to ensure that it is appropriately tailored and proportional to the circumstances. For corporate investigations, one size does not fit all, and bigger is not always better, which is why we work with you to structure our approach. We can also help to identify the most cost effective and productive way to divide the work among different professionals, teaming up with forensics firms, IT providers, accountants, or investigators as appropriate to ensure that we have a tailor-made set of capabilities on-hand to address the situation.
