Prowler began as an open-source AWS security tool in 2016 by Toni de la Fuente and is now a commercial company offering Prowler Cloud as SaaS alongside the open-source Prowler OSS CLI and SDK. It covers cloud and Kubernetes posture management and infrastructure-as-code scanning across major providers.
Additional offerings include Lighthouse AI, MCP integration, and a hub of checks. The project shows about 14,000 GitHub stars.
Innovation Matrix Assessment
Expanded from an AWS script to multi-cloud, Kubernetes, M365 and AI features.
Open checks give practitioners transparent, auditable posture findings and compliance mappings.
$6M seed (Feb 2024) plus $6.5M extension (Apr 2025); 14K GitHub stars; broad but unnamed customer base.
Open-source-first model differs from closed CSPM suites, though CSPM itself is a well-served category.
Long open-source track record gives practical credibility, but no named customer cases were reviewed.
Cloud posture and compliance remain core needs.
Why CISOs Should Care
Transparent, community-vetted cloud checks with a managed option.
What Makes It Different
Open-source origin and community-driven check library, with commercial SaaS layered on top.
The Matrix Verdict
62/100 — INCREMENTAL INNOVATOR
Prowler is an Incremental Innovator. Community adoption is a real strength, while disruption is limited in a mature CSPM market.
Editorial Note: Claims vs. Verified Findings
Customer count claims ('thousands of organizations') are vendor-published. Funding was reported by VentureBeat and SiliconANGLE. HQ was not confirmed.
