Instead of Amazon GuardDuty
Amazon GuardDuty alternatives
Amazon GuardDuty watches AWS accounts and workloads for malicious activity, combining machine learning, anomaly detection, and threat intelligence. It examines logs and events from CloudTrail, VPC Flow Logs, DNS, S3, Aurora, AWS Backup, runtime activity, and AI workloads. Coverage includes EKS, ECS, Fargate, and EC2, with malware checks for EBS and S3 plus protections for Bedrock and SageMaker. Findings can trigger AWS security and workflow services, while foundational deployment needs no extra security infrastructure.

Alternatives become relevant when AWS-only scope, usage-based billing, or regional availability does not fit. GuardDuty has no permanent free plan, offers a 30-day trial, and charges vary by data source and Region. Its access is through API and web platforms. Compare whether you need multi-cloud coverage, Kubernetes or Linux runtime enforcement, policy controls, compliance reporting, a managed service, or software you operate yourself. Platform support, deployment responsibility, response integrations, and free availability also matter when choosing a replacement.
