Understanding your Topstep LLC data breach notification letter
If a Topstep 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
Topstep LLC appears to be a financial services or fintech company, likely specializing in trader funding and evaluation programs. Given the nature of their business, they typically collect and store sensitive personal and financial data, including government-issued identification, banking details, and proprietary trading account information. This security incident was officially reported to the New Hampshire Attorney General in 2025 by the company. If you have received a formal data breach notification letter, it indicates that your personal information was potentially involved in this unauthorized access event. We recommend reviewing the letter carefully to understand the specific scope of the exposure and to take advantage of any identity monitoring services offered by Topstep LLC to protect your financial security.
What to do after the letter
Confirm the notice is genuine
A legitimate Topstep LLC notice references the specific incident reported to the New Hampshire 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.
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.
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.
