Features, pricing, ratings, and pros & cons — compared head-to-head.
Amazon GuardDuty is a free cloud application detection and response tool. CrowdStrike Falcon Shield is a commercial cloud application detection and response tool by CrowdStrike. Compare features, ratings, integrations, and community reviews side by side to find the best cloud application detection and response fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, 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.
Mid-market and enterprise teams managing hybrid cloud infrastructure will get the most from CrowdStrike Falcon Shield because it connects cloud misconfigurations directly to identity risk and active threats in a single console, cutting the noise of standalone CSPM tools. Its coverage across NIST ID.AM, PR.AA, and DE.CM reflects real strength in asset visibility and continuous monitoring where most competitors fragment the picture. Worth noting: it's weaker on data classification and residual risk scoring, meaning teams still need a separate DLP layer for sensitive data handling.
