CST VerdictBased on our analysis of available product data, here is our conclusion:
AWS-native security teams with limited budgets should start with Amazon GuardDuty; it catches account compromise and lateral movement in AWS without the cost of a third-party tool, and the free tier covers threat detection across EC2, IAM, and S3 with no commitment. GuardDuty integrates natively with AWS Security Hub and EventBridge, meaning findings flow directly into your existing automation without connector overhead. Teams needing visibility beyond AWS or prioritizing response automation over detection should look elsewhere; GuardDuty detects threats well but leaves most remediation to you.
AWS security teams with thin staffing will find immediate value in SyntheticSun's automated threat response; it collects and acts on security signals without requiring manual tuning or constant alert triage. The free pricing and serverless architecture mean you can deploy detection and response across your AWS environment without licensing friction or infrastructure overhead. Skip this if your threat model requires visibility outside AWS or if you need forensic-grade response workflows; SyntheticSun prioritizes speed and automation over detailed post-incident investigation.
