zizzl Data Breach

zizzl, a Milwaukee company that runs employee benefits and health insurance administration for employers, has notified people that their names, Social Security numbers and health insurance information were involved in a data security event. Many people getting this letter may never have heard of zizzl.

zizzl, LLC is an employee benefits, HR and insurance-administration platform based in Milwaukee, Wisconsin. Employers use it to manage health coverage and benefits for their workers. That means the people whose data zizzl holds are often employees of zizzl’s business clients, not zizzl’s own customers.

zizzl reported the incident to the Vermont Attorney General and the Massachusetts Office of Consumer Affairs and Business Regulation on October 9, 2026. A Texas Attorney General report, published October 13, 2026, lists names, Social Security numbers and health insurance information for 496 Texans. The company notified people by mail.

The letter states there is “no indication of a specific impact” to recipients’ information and no indication of identity theft or fraud related to the event.

Why You May Not Recognize the Company

zizzl works behind the scenes. If your employer used zizzl to manage your health insurance or benefits, zizzl may have held your Social Security number and insurance details without you ever dealing with the company directly.

zizzl has not said which employers’ workers were affected. If you get a letter from zizzl and do not recognize the name, check with your employer’s HR or benefits team to confirm whether it used zizzl.

What the Letter Does Not Say

The Massachusetts version of zizzl’s letter does not describe what happened. It states: “Due to Massachusetts law, we are unable to provide you with details about the nature of this event.”

zizzl has not publicly disclosed when the incident happened, when it was discovered or how many people were affected in total. State filings so far show at least 519 people across three states:

• Texas: 496
• Massachusetts: 22
• Vermont: 1

These are partial counts. Residents of other states may also have been affected.

A Second Reported Incident in About a Year

This is not the first breach zizzl has reported. According to ClaimDepot, which tracks breach filings, zizzl disclosed a separate incident in 2025 after an unauthorized person accessed one employee’s email account on May 29 and 30, 2025, following a phishing email. ClaimDepot reports that the 2025 incident affected 2,416 people, citing the U.S. Department of Health and Human Services breach portal.

zizzl has not said whether the 2026 event is connected to the 2025 incident.

What Information Was Exposed?

According to the Texas Attorney General report, the information involved includes:

• Names
• Social Security numbers
• Health insurance information

The Massachusetts letter does not list specific data types. Not every person may have had every type of information involved.

What Is zizzl Offering Affected Individuals?

zizzl is offering free credit monitoring, fraud consultation and identity theft restoration through Kroll. The sample letter filed in Massachusetts does not fill in the length of the monitoring or the enrollment deadline, so check your own letter for both.

• Enroll at enroll.krollmonitoring.com using the membership number in your letter.
• You must enroll yourself. Monitoring does not start automatically.
• Questions: (844) 301-0403, 8:00 a.m. to 5:30 p.m. Central Time, Monday through Friday, excluding major U.S. holidays.

Your Health and Financial Identity Are at Risk

A Social Security number paired with health insurance information can be misused in two ways. Criminals can use the Social Security number to open credit or file false tax returns. They can use the insurance information to get medical care or prescriptions billed to your plan, which can leave false entries in your medical records.

Affected individuals can:

• Enroll in the Kroll monitoring before the deadline in your letter.
• Place a free credit freeze with Equifax, Experian and TransUnion.
• Review every Explanation of Benefits from your health plan for visits, tests or prescriptions you did not receive.
• Call your health plan about any claim you do not recognize.
• Ask your employer’s HR team whether it used zizzl and what it knows about the incident.
• Keep your notice letter.

Do You Have Legal Options?

Benefits administrators that handle Social Security numbers and health insurance information have a legal duty to protect it and to notify people promptly when it is exposed. When that duty is not met, affected individuals may have legal rights and remedies worth exploring.

Your Personally Identifiable Information (PII) includes information that can be used to identify you, such as your name and other personal details. Organizations that manage healthcare data are legally required to safeguard this information. When PII is exposed in a data breach, it can potentially be used by cybercriminals to commit identity theft, financial fraud, or other misuse.

Much of the information involved in this incident may also qualify as Protected Health Information (PHI). PHI includes medical or healthcare-related data protected under federal and state privacy laws. When PHI is compromised, it can be misused for medical identity theft or insurance fraud.

Frequently Asked Questions

How many people were affected by the zizzl data breach?

zizzl has not said. State filings show at least 519 people: 496 in Texas, 22 in Massachusetts and 1 in Vermont. These are partial counts, not the total.

What information was exposed?

According to the Texas Attorney General report:

• Names
• Social Security numbers
• Health insurance information

I have never heard of zizzl. Why did I get a letter?

zizzl provides benefits and health insurance administration for employers. If your current or former employer used zizzl, the company may have held your information. Your employer’s HR or benefits team can confirm this.

Why doesn’t my letter explain what happened?

Massachusetts law limits what a company can put in a breach notice sent to Massachusetts residents. Letters sent to residents of that state often leave out how the breach happened and what data was involved. Residents of other states may receive a letter with more detail. Keep your letter, and watch for updates from the company or from state Attorney General filings.

Why is a breach of health insurance information serious?

Health insurance information can be used to get medical care or prescriptions in your name. This is called medical identity theft. It can lead to bills for care you never received and wrong information in your medical records, which can affect your future treatment.

What should I do if I received a letter?

• Enroll in the free Kroll monitoring before your deadline.
• Freeze your credit with all three credit bureaus.
• Read every statement from your health plan.
• Be careful with calls, texts or emails that mention zizzl, your benefits or this breach.
• Save your letter.

Do I have a legal claim?

Companies that manage employees’ Social Security numbers and health insurance information have a duty to protect it and to tell people promptly when it is exposed.
