Which AWS service should the company use to meet these requirements?

Explanations:

Amazon GuardDuty is a threat detection service that monitors for malicious activity and unauthorized behavior, but it does not provide a centralized dashboard for managing security alerts from multiple sources.

Amazon Inspector is a security assessment service that helps improve the security and compliance of applications deployed on AWS, but it focuses on vulnerability assessments rather than consolidating alerts.

Amazon Macie is a data security service that uses machine learning to discover, classify, and protect sensitive data in AWS, but it does not serve as a centralized dashboard for managing security alerts.

AWS Security Hub is designed to aggregate, organize, and prioritize security alerts from multiple AWS services and partner products into a single dashboard, making it the correct choice for managing security alerts effectively.
