Daniel R. Alonso, the former top deputy at the Manhattan District Attorney’s office, is joining a newly-launched consulting firm.

Alonso has been tapped as managing director and general counsel for Exiger, a firm that will advise corporations on governance, compliance and risk matters. He served as chief assistant district attorney from 2010 through early 2014.

The approximately 40-employee firm, which opened Monday, is co-founded by Michael Cherkasky, whose resume includes chairing the New York State Commission on Public Integrity, and Michael Beber, a former president and CEO of Altegrity Risk International.

Alonso was a Manhattan assistant district attorney, serving in the Investigation Division, when Cherkasky was division chief. Alonso also was a commissioner for the New York State Commission on Public Integrity when Cherkasky was its chair.

Alonso said he believed in Cherkasky. “The idea of helping him bring a fantastic team and expand business in a hot area is a fantastic opportunity for me. In this climate right now, companies are facing more regulatory tension than ever before.”

Cherkasky, Exiger’s executive chairman, said in a statement that Alonso’s “understanding of the intricacies of the financial crime landscape will be critical as we continue to build a world-class firm devoted to helping financial institutions and multinational corporations solve some of their largest and most sophisticated financial crime and compliance challenges.”

Alonso, 48, is a graduate of New York University School of Law. His background includes work as a federal prosecutor and litigation partner at Kaye Scholer.
