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 limited budgets or flat headcount should start with Varna to detect anomalous CloudTrail activity without another tool subscription. Its free pricing and native Event Query Language approach mean you get detection logic you can actually read and modify in-house, which matters when your vendor support budget is zero. Skip this if you need response automation or visibility across multi-cloud environments; Varna is AWS-only and built for detection, not remediation.
