Marquis Software Solutions Investigated for Data Breach
Recently, it was revealed that Marquis Software Solutions is under investigation due to a data breach that affects the personal information of approximately 788,000 customers of banks and credit unions using their services. Marquis provides various financial services, including data analytics, CRM tools, compliance reporting, and digital marketing specifically tailored for mortgage lenders, banks, and credit unions.
Details of the Breach
The alarming breach occurred following a ransomware attack on August 14, 2025, where an unauthorized individual infiltrated Marquis's network via its SonicWall firewall. This attack has raised several concerns about the security protocols of Marquis and their ability to safeguard customer information.
Impacted Clients
The breach has impacted various banking institutions and credit unions that previously relied on Marquis's services. This encompasses a total of 74 entities, which include credit unions such as the 1st Northern California Credit Union, Advantage Federal Credit Union, and the Liberty First Credit Union, among many others. The extensive list underlines the reach of the incident across the financial sector.
Delayed Notification Raises Red Flags
Even though the data breach surfaced in August, Marquis did not officially notify affected individuals until around December 3, 2025. This delay may constitute violations of both state and federal laws, as prompt communication is crucial in such scenarios. The specifics of the compromised information include names, addresses, Social Security numbers, Taxpayer Identification Numbers, and financial account details, all of which are critical data that can lead to identity theft.
Potential Consequences for Affected Individuals
Individuals whose sensitive information has been compromised face potential risks of identity theft and various violations of their personal privacy. Due to these risks, affected parties may seek financial compensation for the damages incurred. Furthermore, there’s a possibility of instituting changes to Marquis's cybersecurity practices to ensure that this does not happen again in the future.

If you believe your personal data may have been affected by this data breach, it's paramount to explore your legal rights.
