The U.S. Securities and Exchange Commission has censured New York-based broker-dealer OTC Link LLC and ordered it to pay a $575,000 civil penalty for longstanding violations of Regulation Systems Compliance and Integrity (SCI). The enforcement action stems from the firm's failure to establish, maintain, and enforce required written policies and procedures for its alternative trading system, OTC Link ATS, between August 2016 and March 2025. These deficiencies specifically concerned system security, access control, and application vulnerability management, testing, and remediation.

According to the SEC’s settled order, staff in the Division of Examinations repeatedly identified these gaps during multiple examinations over the relevant period, noting that certain policies remained in draft form or were not finalized. Despite these repeated flags, OTC Link LLC failed to promptly remediate the issues. The Commission found that this lack of adequate policies violated Rules 1001(a)(1), 1001(a)(2), and 1001(a)(3) of Regulation SCI, which mandate that SCI systems possess sufficient capacity, integrity, resiliency, availability, and security to ensure fair and orderly markets. Without admitting the findings, OTC Link agreed to a cease-and-desist order alongside the censure and monetary penalty.
