Cardinal Services, Inc, Cardinal Employer Organization, and Preferred Employer Solutions, collectively (“Cardinal”) data breach: you may be owed a payment

Why you received this letter

Cardinal Services, Inc, Cardinal Employer Organization, and Preferred Employer Solutions, collectively operating as Cardinal, function as professional employer organizations (PEOs), human resources outsourcing providers, and administrative service entities. In this capacity, Cardinal acts as the centralized backbone for countless businesses, managing critical administrative functions such as payroll processing, employee benefits administration, tax filings, and human resources management. Because of this specialized role, Cardinal routinely collects, processes, and stores vast quantities of highly confidential employee information on behalf of client companies and their workers. The nature of their operations requires constant handling of sensitive Personally Identifiable Information (PII) and financial records for thousands of individuals, making the organization a massive repository of high-value data. In 2026, Cardinal formally reported a significant data security incident to the Maine Attorney General, alerting regulators and affected individuals that unauthorized parties had breached their network infrastructure. In incidents involving human resources, payroll, and PEO providers, breaches typically stem from sophisticated cyberattacks, such as unauthorized access to legacy databases, credential stuffing targeting administrative portals, or vulnerabilities within third-party vendor software supply chains. When threat actors successfully penetrate networks of this scale, they often deploy ransomware or silently exfiltrate massive volumes of corporate and employee data over extended periods before detection occurs. The exposure resulting from the Cardinal data breach encompasses deeply sensitive categories of personal information, creating severe, long-term risks for affected individuals. The compromise of full names, dates of birth, and Social Security numbers opens the door to devastating, multi-faceted identity theft and fraudulent credit openings. Furthermore, because Cardinal handles wage, compensation, and tax information, victims face heightened threats of fraudulent tax returns being filed in their names to intercept state and federal refunds. The exposure of direct deposit account details and banking routing numbers creates an immediate danger of unauthorized financial account takeovers and direct funds theft. As a professional employer organization and payroll processor handling sensitive consumer and employee data, Cardinal had strict legal obligations under state data protection statutes, common law negligence standards, and federal trade regulations to maintain robust administrative, technical, and physical safeguards. These legal standards require organizations holding high-risk PEO and payroll data to implement continuous network monitoring, strict multi-factor authentication, robust encryption standards, and regular vulnerability assessments. The occurrence of a widespread data breach strongly indicates a failure to maintain these required security protocols, potentially exposing the company to legal liability for failing to adequately protect the confidential records entrusted to their care. Receiving an official data breach notification letter from Cardinal serves as formal legal acknowledgment that your confidential information was compromised due to inadequate security measures. Under the law, this notification establishes the legal standing necessary to participate in a class action lawsuit aimed at holding Cardinal accountable for their security failures. Affected individuals should know that participating in a class action does not require proof of actual financial loss or identity theft; the increased risk and emotional distress caused by the exposure of your data are sufficient grounds for legal action. Our firm handles these complex data privacy cases on a strict contingency fee basis, meaning you pay absolutely nothing out of pocket, and we only collect a fee if we successfully recover compensation on your behalf.
