Esse Health, a Missouri-based healthcare provider that operates independently as an independent physician group based in the Greater St. Louis area, has recently suffered a devastating data breach that exposed sensitive information of over 263,000 individuals. In April 2025, the company's electronic medical records and phone systems were compromised by a cybercriminal who gained unauthorized access to the network.
The breach was discovered on April 21, 2025, when suspicious activity was identified within the Esse Health network. An investigation was initiated with the assistance of external cybersecurity and forensic specialists, who worked closely with law enforcement agencies to determine the full extent of the attack.
