WHAT HAPPENED?
Recently, JLL reported to the Attorney General of the Commonwealth of Massachusetts that it had experienced a data breach in which sensitive personal identifiable information in its care may have been compromised. According to the breach notice, in August 2025, Salesloft, a third-party software vendor used by JLL, announced a cybersecurity incident affecting its Salesloft Drift product, which JLL uses with its Salesforce customer management platform to support certain operations.1 As a result, JLL launched an investigation to determine the nature of the incident.
Through its investigation, JLL confirmed that sensitive personal information in its Salesforce platform may have been accessed and acquired by an unauthorized third party during the breach. As a result, JLL began a review of the data to determine what information had been impacted as well as identify the specific individuals affected. While the information impacted varies depending on the individual, the type of information potentially exposed includes:
- Name
- Social Security number
- Contact information (email, postal address, phone number)
- Date of birth
On November 17, 2025, JLL began mailing data breach notification letters to impacted individuals. Based on the breach notice sent to Massachusetts residents, JLL is providing affected individuals with a list of the specific types of sensitive information impacted and 24 months of complimentary credit monitoring services.
