SEC’s New Cybersecurity Rules Now in Effect


US-listed companies must now disclose breaches within 4 days.

New cybersecurity rules from the US Securities and Exchange Commission (SEC) went into effect on December 15, 2023, reports Todd Ehret.

The rules “introduce mandatory cyber-incident reporting requirements for all US-listed companies.”

These rules represent a significant shift in disclosure requirements, as “disclosures must be filed within four business days after a company determines that it has experienced a material cyber-incident,” Ehret says.

Companies also must “ensure that best practices are in place across the enterprise to prevent cyberattacks and ensure that a proper response plan is in place that effectively stops or quickly remediates real threats when attacked,” he notes.
