Prowler
TOP PICKOpen-source cloud security posture scanning with framework check packs.
Scans AWS, Azure, GCP and Kubernetes against hundreds of checks and maps them to compliance frameworks including CIS, SOC 2, HIPAA, GDPR and NIST. Runs as a CLI in CI or as a self-hosted app, and produces the technical-control evidence a compliance platform would otherwise gather for you.
Wazuh
Open-source SIEM and XDR with compliance reporting built in.
Agent-based security monitoring with file integrity checks, vulnerability detection, log analysis and prebuilt compliance reporting for PCI DSS, HIPAA, NIST 800-53 and GDPR. Covers the continuous-monitoring requirement that auditors ask about, on infrastructure you run.

Prowler
Strengths
- +Framework mappings are built in — SOC 2, CIS, HIPAA, GDPR, NIST and more, not just raw findings
- +Runs in CI, so posture is checked on every change rather than the week before an audit
- +Covers the part of compliance that is genuinely automatable: technical control state
Trade-offs
- −Produces evidence, not an audit — no auditor relationship, no report
- −No policy management, security training tracking or vendor review workflow
- −Someone has to own the findings; the tool will not chase them
Wazuh
Strengths
- +Genuine SIEM capability, not just configuration scanning
- +Compliance report templates map findings to named framework controls
- +Large deployed base and active development
Trade-offs
- −Real operational weight — agents, indexers and storage to run and tune
- −Overkill if you only need cloud posture and have no on-host estate
- −Again: monitoring and evidence, never the audit itself
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Prowler
if a lower exit cost matters more to you than any single feature, and framework mappings are built in — SOC 2, CIS, HIPAA, GDPR, NIST and more, not just raw findings.
Choose Wazuh
if genuine SIEM capability, not just configuration scanning.
Neither, yet
if both carry a real cost you should weigh first — produces evidence, not an audit — no auditor relationship, no report, and real operational weight — agents, indexers and storage to run and tune. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
Prowler vs Wazuh — common questions
Is Prowler a better fit than Wazuh for compliance automation & security posture?
It depends on what you are optimising for, and the honest split is this: Prowler scores 92 to Wazuh's 88 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Wazuh earns its place on a different axis — genuine SIEM capability, not just configuration scanning. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Prowler keeps its data local or in open formats, so leaving is an export rather than a negotiation. Wazuh is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Prowler or Wazuh?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Prowler and Wazuh both alternatives to Vanta?
Yes — both appear in our Vanta comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Vanta and now choosing between the two replacements, which is a narrower and much easier question.
