Cardinal Services, Inc, Cardinal Employer Organization, and Data Breach

State
Washington
Reported
May 20, 2026

In 2026, Cardinal Services, Inc. and Cardinal Employer Organization, which act as PEOs and administrative service providers handling vast amounts of employee data for client businesses, announced a security incident to the Washington Attorney General. This report indicates an unauthorized compromise within their network environment, impacting the confidential information they hold.

The breach exposed a comprehensive range of sensitive data points. Affected individuals may have had their Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Home Address, and Phone Number compromised. This combination of exposed data creates significant risks, particularly for identity theft and financial fraud, as it provides malicious actors with critical components for impersonation and unauthorized access to accounts.

Companies like Cardinal Services are entrusted with safeguarding highly personal employee data and are legally obligated to implement robust security measures. A data breach of this nature suggests that these security protocols may have been insufficient, leaving vulnerable systems open to unauthorized access. Such failures can lead to significant inconvenience and potential long-term financial harm for those affected.

If you have received a data breach notification letter from Cardinal Services, Inc. or Cardinal Employer Organization, it confirms that your sensitive personal information was part of this incident. This notification provides you with legal standing, meaning you may be able to pursue a claim for the increased risk of harm and potential damages. You are not required to have already suffered financial loss to explore your legal options.

Understanding your rights after a data breach can be complex. We offer a free, no-obligation case review to help you understand what this breach means for you and whether you may be entitled to compensation through a class action lawsuit. There are no out-of-pocket costs unless we successfully recover compensation on your behalf.
