A whistleblower is a person who discloses evidence of wrongdoing, such as fraud, corruption, regulatory violations, discrimination, harassment, or threats to public safety. Whistleblowers are often protected under federal and state laws that prohibit retaliation and provide avenues for confidential or anonymous reporting. In the U.S., major protections come from laws such as the Whistleblower Protection Act, Sarbanes‑Oxley (SOX), Dodd‑Frank, and various industry‑specific regulations.
Whistleblowers play a critical role in corporate accountability, government transparency, and risk management, helping organizations identify internal failures before they escalate into legal, financial, or reputational crises.
