Oklahoma City, OK (February 12, 2025) – The law firm of Federman & Sherwood has initiated an investigation into Ciox Health LLC, dba Datavant Group with respect to their recent data breach.

Datavant promptly began investigating this incident with the assistance of a respected forensic security provider. That investigation concluded on or about August 8, 2024, and determined that an unauthorized individual(s) gained access between May 8, 2024 and May 9, 2024 to certain Datavant data contained in a single user’s mailbox.
