Amazon GuardDuty

Amazon GuardDuty is a managed threat detection service provided by AWS. It helps users identify potential security issues within their cloud environment. This tool is designed to monitor and analyze activity to spot malicious behavior or unauthorized access. It serves as a foundational layer for maintaining visibility into network and account security without requiring complex manual setup or extensive configuration by the user.

You should choose this service when you need an automated way to detect threats in your AWS infrastructure. It is particularly useful for teams looking to enhance their security posture with minimal operational overhead. However, note that while the pricing model is listed as free, a free trial is available, which suggests that ongoing usage beyond the trial period may incur costs or require specific eligibility checks.
