What Happened?
Recently, Mariner Wealth Advisors announced a data breach that may have compromised sensitive personal information.

In response, Mariner immediately initiated its incident response procedures, isolated the affected accounts, and launched an investigation to determine the nature and scope of the incident.
Mariner engaged third-party cybersecurity experts to assist with the investigation and coordinated with federal law enforcement and regulatory authorities. Through its investigation, the company determined that a criminal third party gained unauthorized access to the affected cloud applications and downloaded certain files stored within those accounts.
