Tandem Diabetes Care

Tandem Diabetes Care is a medical technology company that focuses on the design, development, and commercialization of insulin delivery systems for people living with diabetes. Its core product line includes the t:slim X2 insulin pump, which combines a touchscreen interface with rechargeable battery technology. The pump is designed to work with continuous glucose monitoring systems to provide real‑time glucose data to users. Tandem also supplies related consumables such as infusion sets and cartridges that are compatible with its pumps. The company primarily serves patients in the United States, with additional availability in select international markets.

Tandem distinguishes itself by being the first insulin pump manufacturer to receive FDA clearance for remote software updates, allowing new features to be delivered to devices without requiring hardware replacement. The t:slim X2 platform has been cleared with advanced algorithms such as Basal‑IQ and later Control‑IQ, which automate insulin delivery based on glucose trends. The company places a strong emphasis on user‑centered design, aiming to reduce the burden of diabetes management through intuitive interfaces. Tandem has partnered with continuous glucose monitoring providers to enable seamless data sharing between its pumps and external sensors. These attributes position Tandem as an innovator at the intersection of hardware and software in the diabetes care sector.

In January 2020, Tandem Diabetes Care experienced a phishing incident that compromised employee email accounts and allowed unauthorized access for several days. The breach potentially exposed personal information including names, contact details, product usage data, diabetes therapy clinical data, and limited Social Security numbers for approximately 140,000 individuals. Upon discovery, the company secured the affected accounts, engaged external cybersecurity experts, and began a comprehensive investigation and remediation process. Notification letters were mailed to affected individuals, a dedicated support line was established, and credit monitoring services were offered to those whose Social Security numbers were involved. Following the incident, Tandem implemented enhanced email controls, stricter authentication protocols, and restrictions on email data transfers to reduce the risk of similar events.
