Prowler
Open-source multi-cloud security posture and compliance platform with hundreds of controls mapped to CIS, NIST, and ISO 27001.
Technical Architecture & Overview
Prowler is an open-source cloud security platform that automates security and compliance checks across AWS, Azure, GCP, Kubernetes, Microsoft 365, GitHub, and other cloud environments. It contains hundreds of controls mapped to CIS, NIST, PCI DSS, ISO 27001, SOC 2, HIPAA, and other frameworks. Prowler was created by Toni de la Fuente and is maintained by ProwlerPro, Inc. and contributors. It is available as a CLI, SDK, and self-hosted platform, with an optional managed SaaS called Prowler Cloud.
