Background Prosegur Singapore Pte. Ltd. (the “Organisation”) informed the Personal Data Protection Commission (the “Commission”) on 27 August 2025 of a personal data breach involving its file servers (the “Incident”).

The types of personal data affected included a combination of names, addresses, telephone/mobile numbers, NRIC/FIN/passport numbers, countries of origin, photographs, dates of birth, salary histories and a smaller subset of health – mainly vaccination information, belonging to approximately 2,514 individuals. Upon discovery of the Incident, the Organisation took prompt remedial actions including isolating the compromised server, restricting access rights to databases to reduce exposure and renewing all Active Directory user credentials to strengthen identity control and access management.
