WASHINGTON—Federal regulators are considering a requirement that publicly traded companies disclose data breaches and other significant cybersecurity incidents within four days, as they seek to strengthen financial markets’ resilience to online attacks.
The Securities and Exchange Commission is set to propose a rule that would impose mandatory reporting for companies around cybersecurity. The agency’s four commissioners—three Democrats and one Republican—will vote on the proposal in a public meeting Wednesday. If the proposal is approved, it could be finalized after the agency receives and analyzes feedback from the public.
