Case notes

MARQUIS SOFTWARE SOLUTIONS, based in Illinois, has officially reported a data security incident to regulatory authorities. This notification, filed on October 27, 2025, indicates an event involving the compromise of personal information. The public records available do not specify the type of breach that occurred or its exact timeline.

As of the filing date, MARQUIS SOFTWARE SOLUTIONS states that an investigation into the incident is actively underway. This ongoing review aims to determine the full scope of the breach, including how it occurred and what specific data may have been accessed or exfiltrated.

Public filings do not specify the types of personal information that were exposed, nor do they indicate the number of individuals affected by this incident. Therefore, it is important for potentially impacted individuals to understand that the precise nature of the compromised data is not yet disclosed through these records.

To protect themselves, individuals who receive direct notification from MARQUIS SOFTWARE SOLUTIONS should monitor their personal accounts and credit reports for any suspicious activity. It is always wise to review financial statements and transaction histories for anything unauthorized.

Consider placing a fraud alert on your credit files with the three major credit bureaus (Equifax, Experian, and TransUnion) as a precautionary step. This alerts lenders to verify your identity before extending credit in your name.

It is also recommended to be cautious of unsolicited communications, such as emails, texts, or phone calls, that request personal details. Always verify the authenticity of such requests directly with the company using official contact information, not through links or numbers provided in the suspicious communication.
