Abstract: This research paper explores significant cybersecurity incidents that have impacted global firms and industries, pointing to weaknesses in digital infrastructure. Through the examination of high-profile case studies like Equifax, Facebook, JW Marriott, and Sony, the paper looks at causes, effects and operational disruptions that followed. The study focuses on how companies can enhance their security models, adopt proactive approaches, and reduce risks in an increasingly interdependent world. Finally, it emphasizes the need for strong defenses to deter further attacks.
