Amazon GuardDuty

Amazon GuardDuty continuously monitors AWS accounts, workloads, and data for malicious activity and anomalous behavior. It ingests logs from services such as CloudTrail, VPC Flow Logs, and DNS logs, then applies AI/ML models and integrated threat‑intelligence feeds to identify potential security incidents. When a finding is generated, the service provides detailed information that can be used for investigation and remediation.

The service is aimed at security engineers, operations teams, and administrators who need automated, scalable threat detection across a range of AWS compute resources, including EC2 instances, serverless functions, containers, and managed services. It supports protection for storage (S3, EBS), databases (RDS), and backup workloads, offering a unified view of security findings without requiring additional infrastructure.

GuardDuty is a fully managed, continuously operating solution that scales with the number of accounts and resources. It delivers real‑time alerts, correlates events, and supplies remediation guidance, helping organizations respond more quickly to threats while reducing manual analysis effort.
