SEC Cybersecurity Disclosure Rule (2023)

Why it Matters

The SEC Cybersecurity Disclosure Rule enhances accountability in cybersecurity risk management and transparency around material incidents for publicly traded companies.

Key benefits include:

• Strengthen board oversight

Improve executive engagement by requiring the board and management to oversee cybersecurity strategy and risk management processes.

• Enhance investor transparency

Ensure investors receive timely, consistent disclosures about cybersecurity incidents that may impact financial performance or operations.

• Support regulatory compliance

Align information security practices with SEC requirements, reducing risks of enforcement actions and reputational harm.

• Improve incident response accountability

Mandate formal incident response planning and reporting, which leads to more effective organizational response and recovery from cyber events.

• Promote risk-informed governance

Integrate cybersecurity risk assessments into overall governance structures, supporting stronger decision-making and resource allocation.

How it Works

The SEC Cybersecurity Disclosure Rule (2023) structures its requirements around governance, risk management, and incident disclosure obligations for publicly traded companies. The framework focuses on regulatory requirements mandating that registrants disclose their cybersecurity risk management strategies, oversight mechanisms, and any material cybersecurity incidents. It integrates governance domains by emphasizing board and management involvement, as well as ongoing processes for identifying, assessing, and addressing cybersecurity risks.

Organizations implement the SEC Cybersecurity Disclosure Rule by establishing security practices, such as conducting risk assessments, documenting cybersecurity policies, and aligning security controls with regulatory requirements. Compliance teams collaborate with IT and executive leadership to monitor ongoing cybersecurity posture, prepare for disclosure reporting, and develop incident response plans that support timely and accurate regulatory filings. Regular reviews of risk management activities and governance measures ensure continued adherence to the rule.

With SmartSuite, companies can operationalize the SEC Cybersecurity Disclosure Rule through capabilities such as maintaining a control library mapped to SEC requirements, using risk registers to document and track cybersecurity risks, and centralizing policy governance.
