Founded in 1985 and located in Yonkers, the organization provides emergency transportation services, as well as emergency and non-emergency response services to hospitals, private care facilities, and correctional institutions. Empress EMS has more than 200 employees.

In a data breach notice posted on its website, Empress EMS reveals that on July 14, 2022, it identified a ransomware attack that resulted in some of its systems being encrypted.

The subsequent investigation into the incident has revealed that the attackers had gained access to the organization’s network in late May, and that they stole patient data before deploying ransomware on the compromised systems.
