Marquis Software Solutions, Inc. Data Breach Notice (Oregon Attorney General): What Was Exposed & What To Do

Marquis Software Solutions, Inc. notified Oregon residents of a data breach in a filing reported to the Oregon Department of Justice on December 15, 2025. The filing places the incident itself on August 14, 2025, and states that 13,169 people were affected. The notice describes the exposed material as personal information.

Public detail beyond those points remains limited. For people whose information may have been involved, the core facts are the company name, the incident date, the reported number of individuals, and the general category of data named in the notification.

What happened

According to the Oregon Attorney General breach notice, Marquis Software Solutions, Inc. experienced a data incident on August 14, 2025. The company later submitted a filing to the Oregon Department of Justice, reported on December 15, 2025, advising Oregon residents of the event. The filing states that 13,169 people were affected and that personal information was involved.

The public record does not describe the technical method of access, the systems involved, how long unauthorized access lasted, or whether data was exfiltrated, encrypted, or merely viewed. No further breakdown of the 13,169 figure by state or customer category is provided in the disclosed summary. Timing between the August incident date and the December filing is a matter of record; reasons for the interval are not detailed in the available notice.

How a breach like this happens

Incidents that lead to notices of this kind often begin with unauthorized access to corporate systems that store customer, employee, or client records. Common pathways, in general terms and not as a description of this specific event, include compromised credentials, phishing that yields remote access, unpatched software vulnerabilities, misconfigured remote services, or theft of devices or backups that contain copies of databases.

Once inside a network, an attacker may move laterally to file servers, databases, or cloud storage where personal records are kept. Detection can occur through security monitoring, unusual outbound traffic, ransomware notes, or later discovery during routine audits. Organizations then typically investigate scope, determine whose records were involved, and issue notices required by state law when personal information meets statutory thresholds. None of these general patterns identifies a particular threat group or confirms the sequence in the Marquis matter, because the filing does not attribute a method or actor.

About Marquis Software Solutions, Inc.

Marquis Software Solutions, Inc. is a software company. Firms in this sector commonly develop and support business applications, data platforms, or specialized tools used by other organizations. Depending on the product line, such companies may process or store customer contact details, account identifiers, usage records, or other information supplied by clients and end users.

A breach at a software provider can matter beyond the vendor’s own workforce because client organizations sometimes entrust the vendor with data about their customers or members. Even when the exact client list is not public, the presence of personal information in a notice indicates that records tied to individuals were within the scope of the event. The Oregon filing establishes that residents of that state were among those notified.

What was likely exposed

The breach notification names the exposed data as personal information. It does not itemize fields such as Social Security numbers, driver’s license numbers, financial account data, dates of birth, or contact details. Exact contents therefore remain unconfirmed beyond the broad category stated in the notice.

Organizations that hold personal information for software or services work typically maintain names, addresses, email addresses, phone numbers, account or customer identifiers, and sometimes government-issued identifiers or authentication-related data. Whether any of those specific elements were present in this incident is not established by the public filing. Readers should treat only the stated category—“personal information”—as confirmed and regard finer detail as undisclosed.

Why it matters

When personal information is involved in a breach, affected individuals face practical risks that can include targeted phishing, social-engineering attempts that reference real details, and, if sensitive identifiers were present, longer-term identity-theft or account-takeover concerns. The 13,169 figure indicates a substantial number of people may need to monitor accounts and correspondence for unusual activity.

For the organization, a reportable incident brings notification obligations, potential regulatory follow-up, and the operational cost of investigation and remediation. Clients or partners who rely on the company’s software may also reassess data-handling arrangements. None of these consequences requires assuming fault; they follow from the fact that personal information was reported as exposed and that state notice was required.

If your data was in this breach

If you believe you have a relationship with Marquis Software Solutions, Inc. or received a notice tied to this filing, begin by reading any official letter carefully for the exact data elements it lists and for any offered support such as credit monitoring. Place fraud alerts or credit freezes with the major consumer reporting agencies if sensitive identifiers may have been involved, and monitor bank, credit card, and online accounts for unfamiliar activity. Be cautious of unsolicited calls or messages that claim to relate to the breach and ask for passwords or payment.

You can also run a free exposure scan of your email address to check whether your information has already surfaced in known breach datasets, which can help you prioritize password changes and ongoing monitoring. Keep records of any notices you receive and of steps you take, and consult official state or federal consumer resources if you encounter clear signs of identity misuse.
