Description
On November 3 2025, Strategic Investment Solutions Inc. (SIS) detected a cybersecurity incident affecting some of its network servers, prompting an internal investigation that revealed an unauthorized party may have accessed information stored on those systems. The breach was identified by SIS on or about that date, and the company subsequently learned that the intrusion could have exposed personal details such as names and other identifying information belonging to clients of its fiduciary wealth management, tax, and investment advisory services. No further specifics about the attacker’s methods, tools, or motives were disclosed in the available sources. Following the discovery, SIS initiated an internal review to determine the scope of the compromise and to secure the affected servers against additional unauthorized access. The company also notified potentially impacted individuals, as required by applicable data breach disclosure laws, and began coordinating with external legal counsel to address potential liability.

In response to the incident, Edelson Lechtzin LLP, a national class action law firm with offices in Pennsylvania and California, announced on February 15 2026 that it is investigating data privacy claims on behalf of SIS clients whose data may have been compromised. The firm stated that it is pursuing a class action lawsuit to seek legal remedies for individuals whose sensitive personal data might have been exposed in the breach. Edelson Lechtzin LLP advised recipients of any breach notification to take protective steps, including regularly reviewing account statements and monitoring credit reports for signs of identity theft or fraud. The law firm provided contact information for further inquiries, including a phone number, email address, and website. No additional details regarding remediation efforts undertaken by SIS, such as patching vulnerabilities, implementing enhanced monitoring, or offering identity protection services, were included in the source material. The narrative concludes with the ongoing legal investigation and the advised precautionary measures for affected individuals.
