Advisors Advantage Network, which operates through Securities Support Unit, LLP, filed a sample data breach notice dated September 28, 2026 with the Massachusetts Attorney General. The notice says some personal information was involved in an incident.
Advisors Advantage Network’s Data Breach Investigation
Advisors Advantage Network, also referred to in its notice as AAN, provides supervision and compliance services to certain financial advisors who are licensed to offer securities and advisory services through Osaic Wealth, Inc. The Massachusetts filing lists the organization as Securities Support Unit, LLP, doing business as Advisors Advantage Network. In a notice dated September 28, 2026, the organization told recipients that it was writing about an incident that involved some of their information.
The copy filed with the state is a sample letter, and it leaves out most of the facts people would want. It does not say when the incident happened, when it was discovered, how it occurred, or how many people were notified. No public count has been published so far. The section that should name the categories of personal information reads as a placeholder rather than a real list, so the specific types of data involved have not been publicly described. We are not guessing at what they might be.
What the notice does say is that the organization is reviewing its safeguards and the security of its systems to help prevent a similar incident in the future, and that it is taking steps to strengthen its existing security measures. It does not describe what safeguards were in place beforehand or what specific changes are planned.
The organization is offering a complimentary two-year membership in identity monitoring through Cyberscout, a TransUnion company. The enrollment materials describe single bureau credit monitoring, a single bureau credit report and credit score, and fraud assistance. People must enroll within 90 days of the date on their letter and use the unique activation code printed in their own copy. A toll-free assistance line is listed for questions.
Firms that supervise financial advisors hold the kind of records that attract criminals. Compliance files can include client account details, identification numbers, financial statements, and correspondence between advisors and their clients. The notice does not say whether any of those categories were involved here, and we mention them only as general context on why this sector is a frequent target.
When a notice offers two years of identity monitoring, it usually signals that the information involved is sensitive enough to warrant extended protection, though the notice itself does not confirm that. Recipients should not assume the offer means nothing was taken, and they should also not assume the worst. The practical approach is to read the full letter, keep a copy, and take the protective steps it describes.
The letter reminds recipients to stay alert for fraud or identity theft by reviewing account statements and free credit reports over the next 12 to 24 months. It also explains fraud alerts, which last one year for an initial alert and seven years for an extended alert, and credit or security freezes, which are free to place and lift. People can request a free credit report from each of the three nationwide credit bureaus.
Because a notice like this can arrive months after an incident, many people only learn about it long after any misuse could have started. If you have worked with an advisor supported by Advisors Advantage Network or Osaic Wealth, watch your mail for a letter and keep it with your records.
We will update this page if the organization or a regulator publishes more detail, including the dates of the incident, the categories of information involved and the number of people notified. Until then, the guidance in this article is based only on what the filed notice actually says.
