Washington Trust Company of Westerly and Marquis Software Solutions Data Breach Notification Letter — Free Case Review

As institutions anchoring regional banking and financial services, The Washington Trust Company of Westerly alongside software vendors like Marquis Software Solutions manage immense volumes of sensitive consumer wealth, transactional records, and personally identifiable information. Washington Trust Company of Westerly operates as a deeply established financial institution offering personal banking, wealth management, and commercial lending, while Marquis Software Solutions provides specialized data processing and software infrastructure crucial for modern financial institutions. Because of this core mission, these entities routinely collect, analyze, and retain a wide array of confidential customer data, making them prime targets for malicious actors seeking to exploit systemic vulnerabilities for financial gain.

In 2025, a significant security incident involving Washington Trust Company of Westerly and Marquis Software Solutions was officially reported to the New Hampshire Attorney General's office. While the precise mechanics of the breach are still being scrutinized, incidents impacting financial services and third-party software vendors typically involve sophisticated cyberattacks, unauthorized network infiltration, or third-party vendor compromises. When a vendor or financial institution suffers an intrusion, malicious actors often exploit weaknesses in digital defenses, potentially gaining covert access to internal databases, shared servers, or managed file transfer environments where sensitive consumer information is stored.

The resulting data exposure compromises deeply personal and financially ruinous information, including full names, Social Security numbers, financial account numbers, routing numbers, dates of birth, and sensitive transactional details. The exposure of this specific combination of data creates immediate and severe risks for affected consumers. Unlike a compromised password that can be easily reset, core identifiers like Social Security numbers and financial account details cannot be changed. This exposes victims to long-term threats such as unauthorized bank withdrawals, fraudulent credit applications opened in their names, tax fraud, and sophisticated phishing schemes designed to target financial assets.

Financial institutions and their software partners are bound by stringent federal and state regulatory frameworks, most notably the Gramm-Leach-Bliley Act (GLBA) and applicable state consumer protection laws. Under the GLBA, financial institutions and their service providers are legally mandated to implement rigorous administrative, technical, and physical safeguards to protect customer nonpublic personal information from unauthorized access and disclosure. A security incident of this magnitude strongly suggests potential failures in adhering to these statutory security obligations, raising serious questions about whether adequate encryption, access controls, and vendor oversight mechanisms were maintained.

For consumers who have received a data breach notification letter from Washington Trust Company of Westerly and Marquis Software Solutions, this correspondence serves as an official acknowledgment that their private information was compromised due to inadequate security measures. Legally, the receipt of this notice establishes the foundation for prospective class action litigation, affirming that affected individuals have suffered an invasion of their privacy and an elevated, imminent risk of identity theft.
