SEC Cybersecurity Disclosure Rules (2023)

¿Qué es SEC Cybersecurity Disclosure Rules (2023)?

SEC Cybersecurity Disclosure Rules (2023)U.S. Securities and Exchange Commission rules adopted in July 2023 requiring public companies to disclose material cyber incidents on Form 8-K within four business days and to describe their cybersecurity risk management, strategy, and governance annually on Form 10-K.


The SEC's Cybersecurity Disclosure Rules, finalized 26 July 2023 and largely effective by December 2023, materially changed cyber-incident reporting for U.S.-listed companies. Public registrants must file Form 8-K Item 1.05 within four business days of determining that a cybersecurity incident is material, describing its nature, scope, timing, and material impact (including reasonably likely impacts). Determination of materiality must be made 'without unreasonable delay'. Annually, the 10-K must include Item 106 disclosures on processes for assessing/managing cyber risk, the role of management and the board in cyber oversight, and any material risks from cyber threats. A narrow law-enforcement-delay carve-out exists when the U.S. Attorney General determines that disclosure would substantially threaten public safety or national security. Foreign private issuers face analogous obligations on Form 6-K and 20-F. Since the rule took effect, dozens of 8-Ks have been filed (MGM Resorts, Clorox, Caesars, ScreenConnect/ConnectWise, Halliburton, CDK Global, UnitedHealth, etc.), and the SEC has separately pursued enforcement against issuers for misleading or absent disclosures.
