Cloud Security Posture Management (CSPM) is essential for managing the complexities and security risks of multi-cloud environments, which include platforms like AWS, Azure, Google Cloud, and Kubernetes. CSPM tools provide automation and visibility to help organizations maintain security and compliance across diverse systems with unique configurations and rules. Prowler is an open-source CSPM solution that offers comprehensive coverage, automated compliance checks, and centralized visibility, addressing common challenges such as identity management complexity, configuration drift, and shadow IT. Developed by Toni de la Fuente, Prowler emerged as a scalable, cost-effective platform that aids security teams in identifying and mitigating vulnerabilities early, ensuring consistent security without vendor lock-in. Implementing CSPM requires strategic planning and alignment across teams, with a phased approach recommended to minimize disruption and maximize security benefits.
