Understanding your Hartshorne Plunkard Architecture LLC data breach notification letter

If a Hartshorne Plunkard Architecture LLC letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.

Why you received this letter

Hartshorne Plunkard Architecture LLC is a professional architecture and design firm that manages complex project documentation, client contracts, and employee records. In the course of their business operations, the firm typically collects and stores sensitive information, including employee Social Security numbers, payroll details, and proprietary client project data. This data breach was officially reported to the Indiana Attorney General in 2025, confirming that unauthorized parties may have accessed files maintained on the company's systems. If you have received a formal data breach notification letter from the firm, it indicates that your personal information was likely contained within the impacted records. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered.

What to do after the letter

  1. Confirm the notice is genuine

    A legitimate Hartshorne Plunkard Architecture LLC notice references the specific incident reported to the Indiana Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.

  2. Keep the letter — it is your proof of connection

    The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.

  3. Protect your accounts and credit

    Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.

  4. Find out whether you have a claim

    Whether the Hartshorne Plunkard Architecture LLC breach gives you a legal claim depends on the facts. A free, no-obligation case review will tell you where you stand — there is no cost and no commitment to find out.
