Xsolis Data Breach Impacts Over 1.3 Million Individuals Across the Nation

Xsolis Inc., an AI-driven healthcare technology company that provides case and utilization management services to healthcare organizations, disclosed a data breach that may have exposed certain personal information, impacting 1,396,519 total individuals, including 26,700 Texas residents, 24,711 Washington residents, 192 Massachusetts residents and 154 Indiana residents.

Because Xsolis operates as a vendor to hospitals and health plans, individuals whose information was exposed may not have a direct relationship with the company. Their personal and health data was shared with Xsolis by the healthcare organizations it serves, which means patients and plan members may be among those affected even if they have never heard of Xsolis before.

On Jan. 20, 2026, a targeted phishing attack compromised a limited portion of the Xsolis technology environment, according to the company's notification.

After detecting the unauthorized activity, Xsolis worked to contain it. An investigation analyzed the scope of the unauthorized access and determined that an unauthorized actor had gained access to a compromised portion of the environment.

The types of information exposed included names, addresses, dates of birth, health insurance information, Social Security numbers and medical treatment information.

Xsolis posted a notice about the incident on a dedicated website. The company also disclosed the incident to the California Attorney General and to the Nebraska Attorney General.
