Antitrust refers to a set of laws and regulations aimed at promoting fair competition and preventing monopolistic practices in the marketplace. These laws prohibit companies from engaging in activities that unfairly limit competition, such as price fixing, collusion, or mergers that would create dominant market players. Antitrust regulations are enforced by government authorities to ensure that consumers benefit from competitive prices, innovation, and choice. In the context of cybersecurity, antitrust considerations may arise when large tech companies control critical digital infrastructure or data, potentially impacting market fairness and security.
