Antitrust review is a regulator’s examination of a merger, acquisition, or business coordination to determine whether it could reduce competition, limit consumer choice, or weaken innovation. Authorities may assess market concentration, barriers to entry, and the parties’ incentives and ability to restrict rivals.
In strategic technology sectors, review can also consider how a deal may affect investment, innovation, and reliance on a small number of suppliers. These factors can matter to cybersecurity because reorganizing critical providers may change dependencies, oversight, and resilience planning. Antitrust review does not itself establish that a merger is harmful or beneficial; it is a process for evaluating potential effects before regulators decide whether to approve it, impose conditions, or block it.
