Osano Compliance Checker Verify Your Setup Is Working
Osano is a trusted consent management platform built for small and mid-size businesses. Its simple setup makes it easy to get started - but third-party scripts, tag manager rules, and embedded widgets can still fire outside Osano's control, silently dropping cookies with no warning from the Osano dashboard.
We work alongside Osano - not against it
Osano manages your consent configuration and vendor disclosures. We independently verify that configuration produces the right outcome in a real browser - catching issues that Osano cannot see from inside the page.
What we verify that Osano alone cannot confirm
Osano controls what it controls. These six checks require independent observation from outside the page.
| Check | Why Osano alone cannot confirm it |
|---|---|
| Pre-consent cookies | Osano provides a simple consent manager - but third-party scripts loaded via tag managers, embedded widgets, and CDN-hosted libraries can fire before Osano's blocking logic runs. |
| Google Consent Mode v2 signals | Osano can generate Consent Mode signals, but signal timing and the presence of all 4 v2 signals (ad_user_data, ad_personalization) must be verified from outside the page. |
| Reject All enforcement | A site update, new integration, or tag manager deployment can add scripts that fire regardless of the consent state Osano tracks - with no alert from the Osano dashboard. |
| GPC signal handling | Global Privacy Control requires a browser-level test. Osano can be configured to honor GPC signals - but the dashboard setting does not confirm it works in a real browser session. |
| Dark pattern checks | Osano provides the consent dialog framework and configuration options. The implementation choices - button prominence, dismiss behavior, category labels - are outside Osano's enforcement scope. |
| Multi-region behavior (up to 15 regions) | Osano uses geo-targeted rules for different privacy frameworks. We test from actual EU, California, UK, and other jurisdiction IPs to verify that region-specific flows work as configured. |
