Prowler is an open-source cloud security platform that automates security and compliance auditing across AWS, Azure, GCP, and other cloud environments.
Prowler addresses the challenge of maintaining consistent security posture and compliance across multi-cloud infrastructure by running automated security checks against cloud resources. The tool evaluates configurations, permissions, and security settings against established benchmarks and compliance frameworks, identifying misconfigurations and policy violations that could expose organizations to risk. It operates by connecting to cloud provider APIs to inspect resources and compare them against predefined security checks and compliance standards.
Organizations should adopt Prowler if they operate across multiple cloud providers and need centralized visibility into security and compliance status without building custom auditing infrastructure. The tool suits teams managing AWS, Azure, or GCP environments who want to enforce CIS benchmarks, GDPR compliance, or other regulatory requirements at scale. It is particularly valuable for DevSecOps workflows where continuous security monitoring needs to integrate into existing deployment pipelines. The project provides thousands of ready-to-use checks covering common security concerns like IAM configuration, encryption, logging, and access controls, reducing the effort required to establish baseline security assessments.
The project maintains active development with regular updates to checks and compliance frameworks. The codebase shows ongoing refinement of existing functionality rather than major architectural shifts. The tool receives consistent attention to expanding cloud provider coverage and adding new compliance standards. Integration capabilities are actively developed to support diverse deployment scenarios and downstream security tools.
