CMP vendors who sell the consent banner also grade your compliance — a structural conflict of interest. We are an independent scanner with no CMP affiliation, detecting issues that CMP tools are incentivised to downplay.

Comparison based on publicly available documentation and our own testing as of March 2026. Features may have changed.
CMP vendors grade compliance with their own product. Issues caused by their banner configuration are often omitted or downplayed — you are relying on the vendor to audit themselves.
Built-in CMP scanners typically check only cookies they manage. Third-party trackers loaded by ad scripts, analytics pixels, or tag managers often fall outside their scanning scope entirely.
As an independent scanner, we have zero incentive to minimize findings. If your site leaks data before consent or makes reject buttons hard to find, we report it — regardless of which CMP you use.
Run a free scan and compare the findings with what your CMP dashboard shows. Most teams find issues their current tools missed.
