Top free cloud security tools include Prowler (AWS security auditing), ScoutSuite (multi-cloud auditing), Checkov (IaC scanning), Trivy (container vulnerability scanning), and Falco (runtime security). These cover configuration auditing, compliance, and threat detection across major cloud providers.
Use Prowler for automated AWS security auditing, CloudTrail for logging, and Config for compliance monitoring. Open source tools like ScoutSuite and Steampipe provide comprehensive visibility into misconfigurations without cost.
Cloud Security Posture Management (CSPM) tools continuously monitor cloud infrastructure for misconfigurations and compliance violations. Free CSPM tools include Prowler, CloudSploit, and ScoutSuite. They check against CIS Benchmarks, NIST, PCI DSS, and other frameworks.
Tools like Checkov, tfsec, Terrascan, and KICS scan Terraform, CloudFormation, Kubernetes manifests, and other IaC files for security misconfigurations before deployment. Integrating these into CI/CD pipelines prevents insecure infrastructure from reaching production.
