Marquis Software Solutions filed a data breach notification with the California Attorney General’s office on March 16, 2026. The official notification letter was submitted as a scanned document, and no readable text could be extracted from it. That means we cannot tell you, based on this filing alone, exactly what happened, how the incident occurred, or what specific information was involved. We’re publishing what is confirmed — that a notice was filed — and will update this page if a readable version of the letter becomes available.
Because the filing text isn’t extractable, we don’t know how many individuals were notified or whether the affected group is limited to California residents or extends further. If you received a letter directly from Marquis Software Solutions, that letter is the most reliable source for scope and details, and you should keep it for your records.
What information was exposed?
- The specific categories of personal information involved were not disclosed in the readable portion of this filing.
- Data breach notification letters generally cover things like names, contact details, Social Security numbers, financial account numbers, or health information — but we cannot confirm which, if any, applied here without a readable copy of the letter.
What should you do now?
- Keep the physical or emailed notification letter you received, since it may contain details (like an account number or specific data types) not available in this summary.
- Watch your bank, credit card, and any accounts you have with Marquis Software Solutions for unfamiliar activity, even if you’re not sure exactly what data was involved.
- Be cautious of unexpected emails, calls, or texts referencing this incident, since scammers sometimes use news of a breach to impersonate companies.
- Consider placing a free fraud alert with one of the three major credit bureaus (Equifax, Experian, TransUnion) as a precaution while more details become available.
- Since the exact data exposed isn’t confirmed, it may be worth signing up for a service like Aura or LifeLock, which can alert you if your personal information turns up somewhere it shouldn’t.
- If you have any account with this company, consider updating your password and enabling two-factor authentication where available.
