What each tool is for
OneTrust
CookieComply
- Enterprise consent banner and preference center — Core CMPNo banner or consent storage
- Cookie categorization inside the CMP — Yes, for deployed propertiesYes, from a live Chrome capture of any page you open
- Proof of pre-consent loads for audits — Indirect via CMP configYes — extension records what loads before Accept
- Client-ready GDPR cookie report — Policy / CMP exportsYes — inventory, purpose, risk, draft consent copy
- Requires script on every production page — Typical for CMPNo site-wide install; scan per URL in Chrome
When CookieComply fits alongside OneTrust
- Compliance wants a live production capture, not only what the CMP configuration claims.
- You are onboarding a new subdomain or vendor stack and need a fast baseline before updating OneTrust categories.
- Agencies deliver quarterly audits and cannot rely on each client’s OneTrust admin access for every check.
When OneTrust (or similar) stays mandatory
Regulators and users expect a visible consent experience and enforced blocking. OneTrust (and other CMPs) own that surface. CookieComply does not block tags or write consent cookies on your visitors’ browsers.
Running a CMP and CookieComply together
Run a CookieComply scan on staging or production, reconcile findings with your OneTrust cookie dictionary, then fix mis-tagged scripts or missing disclosures. The CMP handles choice; the audit proves behavior matches policy.
