Who it is for
Pros
- Free open-source core with wide framework coverage
- Read-only, agentless access that does not change your environment
- Prioritization cuts the noise of thousands of raw findings
Limitations
- The cloud trial is 15 days and paid pricing can change
- The volume of findings needs triage before it becomes useful
- Setup requires cloud credentials and permission decisions
What Prowler Cloud is
Prowler is an open-source cloud security platform. It scans multiple environments, including AWS, Azure, Google Cloud, Kubernetes, GitHub, and Microsoft 365, from one control plane, and it carries more than 2,500 security checks mapped to over 70 compliance frameworks such as CIS, NIST, PCI, and GDPR. Findings are sorted by risk severity, context, and business impact so a team starts with what matters instead of a wall of alerts. Each finding comes with remediation guidance, and AI assistance can generate explanations and suggested fixes. Access is read-only through IAM roles or service principals, no agents are deployed into the environment, and the project is SOC 2 Type II certified. The open-source version is free, and the cloud version has a 15-day trial.
What you can do with it
- Scan multiple clouds and services from one place
- Map results to compliance frameworks automatically
- Prioritize findings by severity and business impact
- Follow step-by-step remediation guidance
- Track posture over time with rescans and trend charts
Who it is for
- Security engineers who need automated multi-cloud scanning
- DevOps and platform engineers wiring checks into pipelines
- Compliance and audit staff producing framework evidence
- CISOs and cloud architects needing a cross-account risk view
What to watch out for
The cloud trial lasts 15 days and paid pricing can change, so plan procurement before the trial lapses. More than 2,500 checks produce a lot of output, and without triage the noise can bury the issues that matter. Connecting accounts requires read-only credentials, which still needs a permissions decision and sign-off in most organizations. Remediation is guidance, not automation, so someone has to apply the fixes and rescan.
