+### Known Findings
+
+A small number of findings remain in the published images and cannot be resolved by Prowler: the upstream project has released no fix, the package cannot be removed without breaking the image, or the finding comes from a vendored SBOM rather than from a package that is actually installed. Alternative base distributions have been evaluated and none currently satisfies both the vulnerability profile and the runtime requirements of every supported provider.
+
+Each suppression is recorded in [`.trivyignore`](https://github.com/prowler-cloud/prowler/blob/master/.trivyignore) with the reason it cannot be fixed, why it is not exploitable in Prowler's runtime, and an expiry date that forces re-review. Nothing is suppressed without that rationale, and a build fails on any critical finding that is not listed there.
