Prowler Cloud Security
Open-source cloud security posture management (CSPM) tool that audits AWS, Azure, and GCP configurations against security benchmarks (CIS, NIST, SOC2, PCI-DSS, HIPAA, GDPR). Prowler runs as a CLI or Python library, executing hundreds of security checks against live cloud environments. Prowler Cloud (SaaS) provides a REST API for managing assessments, findings, and compliance reporting.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Apache 2.0 open-source — fully auditable. CLI uses cloud provider's own IAM — no credential storage. Prowler Cloud SOC2. Strong security-focused community. Open-source version processes all data locally.
⚡ Reliability
Best When
You need open-source cloud security benchmarking across AWS/Azure/GCP with structured output, compliance framework mapping, and API access to findings.
Avoid When
You need commercial-grade CSPM with asset inventory, continuous monitoring, and managed compliance reporting — Wiz or Prisma Cloud offer more enterprise features.
Use Cases
- • Run automated cloud security audits in agent-driven compliance pipelines — scan AWS/Azure/GCP for misconfigurations and compliance gaps
- • Trigger Prowler assessments via API and retrieve structured findings for agent-driven remediation workflows
- • Monitor AI infrastructure cloud resources for continuous compliance against SOC2, PCI-DSS, or CIS benchmarks
- • Generate compliance reports for specific frameworks (CIS AWS, NIST 800-53) as part of agent audit automation
- • Integrate Prowler findings into security dashboards or SIEM systems via API for ongoing cloud security monitoring
Not For
- • IaC scanning of Terraform files before deployment — Prowler audits live cloud resources; use tfsec or Checkov for Terraform-time scanning
- • Runtime container security — Prowler checks cloud configuration, not container workloads; use Falco for container runtime
- • Application vulnerability scanning — Prowler is cloud posture only; use Snyk or Trivy for application and container vulnerabilities
Interface
Authentication
Prowler Cloud API uses API keys for authentication. CLI uses cloud provider credentials (AWS IAM, Azure SP, GCP SA) directly — no Prowler authentication needed for open-source CLI. API keys generated in Prowler Cloud dashboard.
Pricing
Open-source version is Apache 2.0 licensed and fully featured for CLI use. Prowler Cloud SaaS provides managed scanning, API, dashboard, and compliance reporting. The REST API is Prowler Cloud-only.
Agent Metadata
Known Gotchas
- ⚠ Prowler requires appropriate IAM permissions on the scanned cloud account — security-read-only roles are sufficient but must be explicitly configured
- ⚠ Large cloud accounts (1000+ resources) can take 30+ minutes to scan — agents must use async scan triggering and poll for results
- ⚠ Some checks are region-specific — agents must specify regions to scan or accept global scanning with longer runtimes
- ⚠ Muted findings are excluded from severity counts by default — agents must understand muted vs active finding states
- ⚠ Prowler Cloud API requires separate authentication from CLI cloud provider credentials — two different auth mechanisms to manage
- ⚠ Compliance framework mapping (e.g., NIST 800-53) is approximate — Prowler maps its checks to framework controls, but not all controls are covered
- ⚠ Open-source CLI check list evolves rapidly — version-pin CLI in production to avoid check behavior changes between runs
