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

Explanations:

AWS Firewall Manager enables the centralized management of security policies across multiple AWS accounts, allowing the company to configure and manage Amazon VPC security groups effectively across its organization.

Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior, but it does not manage VPC security groups or provide centralized configuration.

Amazon Detective helps analyze and investigate security incidents and potential security issues, but it does not provide capabilities for managing security groups across multiple accounts.

AWS WAF (Web Application Firewall) is focused on protecting web applications from common web exploits and does not offer functionality for managing VPC security groups across multiple AWS accounts.
