Marquis Software Solutions Data Breach Details:

In August 2025, Marquis Software Solutions, a Texas-based provider of marketing and compliance tools for financial institutions, identified anomalous network behavior that led to the confirmation of a significant cybersecurity incident. The incident unfolded when unauthorized actors infiltrated the company's systems, potentially extracting sensitive files containing personal details such as names, Social Security numbers, dates of birth, and account information from client databases, primarily affecting members of various banks and credit unions.

An ensuing probe, supported by external cybersecurity specialists and reported to authorities including federal law enforcement and state attorneys general, revealed the breach's scope impacting hundreds of thousands of individuals across multiple states, with notifications to affected parties commencing around October 27, 2025. To address fallout, Marquis introduced bolstering measures like advanced authentication protocols and monitoring tools, while extending no-cost identity monitoring services to those notified, though no confirmed instances of data exploitation have been documented to date.

As a result of the data breach, Marquis Software Solutions is offering free credit monitoring and/or identity theft protection services to some affected individuals.
