Boston Gets New CISO, Chief Data Officer


On Friday, Mayor Marty Walsh announced that Greg McCarthy will serve as the city’s Chief Information Security Officer and Stefanie Costa Leabo will become Chief Data Officer. Both roles represent promotions for the two appointees who have been part of the technology department in the city for several years.

McCarthy takes over as the first-ever CISO for the city. He will lead the cybersecurity team within the Department of Innovation and Technology. McCarthy has been a part of Boston’s cybersecurity team since 2010, helping to develop the City’s first Cybersecurity Awareness Program for employees.

Prior to joining the cybersecurity team, McCarthy spent five years as a Principal Research Technician at the Rhode Island Department of Corrections.

In her role as Chief Data Officer, Costa Leabo will be tasked with leading the analytics team within the Department of Innovation and Technology. Costa Leabo has been a member of the analytics team since 2015. In her work with the analytics team, she led the development and release of Mayor Walsh’s CityScore initiative and facilitated the launch of Boston’s Community Assistance Team pilot program.

CityScore is a performance metrics scoring system that Boston uses to determine how well it is handling service delivery and progress toward city goals. The Community Assistance Team works alongside EMTs by responding to calls that do not require patient transport. CAT was created in an effort to help make the use of ambulances more efficient by sending them only when they are actually needed.
