About Mullen Coughlin:

Founded by John Mullen, Jim Prendergast, Chris DiIenno, and Jennifer Coughlin, Mullen Coughlin LLC is a law firm uniquely dedicated to solely servicing organizations of every size and from every industry with data privacy crises, incidents, and risks. It’s all we do! Organizations large and small, regardless of geographic footprint and industry sector, face complicated and constantly changing risks to the security of their information systems and their data. Complex state, federal, and international laws, as well as contracts, impose requirements on organizations to protect against the compromise, loss, or exposure of data, and force them to take certain steps to disclose such events to individuals, clients, the media and regulators. Organizations are well-served to engage counsel highly experienced and knowledgeable regarding these risks and regulations. Having handled thousands of events, Mullen Coughlin is the largest team of experienced attorneys focused on providing tailored data privacy and incident response services, including pre-breach planning and compliance, breach incident response, regulatory investigation and management, and privacy litigation defense under the umbrella of cyber insurance. Much like the insurance industry itself, Mullen Coughlin serves organizations from every sector such as Financial/Banking Institutions, Healthcare, Retail, Education, Government and Non-Profit, and Professional Services, to name a few.
