Prowler vs CloudQuery
Both are alternatives to Vanta. Here's how they stack up — verified facts, no spin.
Also searched as CloudQuery vs Prowler — same comparison, one verdict.
Both are compliance automation & security posture tools with the same broad shape, but Prowler scores 92 against CloudQuery's 80 on data ownership and exit cost — the gap is in how easily you could leave.
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.
CloudQuery
Sync cloud infrastructure into your own database, then ask compliance questions of it.
An ELT framework that pulls cloud, SaaS and identity configuration into Postgres or a warehouse you own. Compliance becomes a query against your own data rather than a feature of somebody's platform, which also makes the evidence yours to keep.
Side by side
6 points of comparison, every one read from a verified field. Green marks the side that wins a row outright. A dash means we do not hold that fact — never that it is zero.

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
CloudQuery
Strengths
- +The evidence lands in a database you control and can retain for years
- +Broad source coverage beyond cloud — identity, SaaS, code hosting
- +Fits teams that already have a warehouse and BI layer
Trade-offs
- −You build the compliance logic; it ships the data, not the verdict
- −Several plugins and features sit behind the commercial tier
- −Furthest of these from anything an auditor would recognise unaided
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 CloudQuery
if the evidence lands in a database you control and can retain for years.
Neither, yet
if both carry a real cost you should weigh first — produces evidence, not an audit — no auditor relationship, no report, and you build the compliance logic; it ships the data, not the verdict. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
Prowler vs CloudQuery — common questions
Is Prowler a better fit than CloudQuery for compliance automation & security posture?
It depends on what you are optimising for, and the honest split is this: Prowler scores 92 to CloudQuery's 80 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. CloudQuery earns its place on a different axis — the evidence lands in a database you control and can retain for years. 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. CloudQuery 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 CloudQuery?
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 CloudQuery 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.
