The Tocqueville Asset Management Data Breach: Reported Filing Facts
Tocqueville Asset Management is a financial institution that provides investment management and advisory services to high-net-worth individuals and institutional clients. As part of their standard operations, the firm collects and maintains highly sensitive personal and financial data, including investment account details, tax documentation, and government-issued identification numbers required for regulatory compliance. In 2025, the company officially reported a data security incident to the New Hampshire Attorney General, confirming that unauthorized parties may have accessed sensitive information. If you have received a formal data breach notification letter from the firm, it indicates that your personal information was likely stored within their systems at the time of the incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered.
