These three are the names that come up most often when a site needs a consent-management platform. They solve the same core problem — show a banner, record a decision, block scripts until consent — but they're built for different sizes of company, and picking the wrong one is a common source of avoidable compliance gaps.
Cookiebot: best for small-to-mid sites that want it done fast
Cookiebot (by Usercentrics, confusingly — more below) leans on an automated scanner to detect cookies and pre-fill the banner's category list. Setup is genuinely fast, pricing is accessible for a single site, and the free tier covers very small sites outright. The tradeoff: the automated categorization isn't perfect, and a site with a lot of custom or agency-added scripts often needs manual cleanup of what Cookiebot's scanner missed or miscategorized.
Usercentrics: the enterprise sibling, built for complexity
Usercentrics (the parent company now owns Cookiebot too) targets larger organizations — multi-brand portfolios, complex consent workflows, deeper CMS/tag-manager integrations, and more granular reporting for a legal or compliance team. It's more capable, and priced accordingly; most single-site small businesses are paying for capability they don't need.
OneTrust: the enterprise-privacy-suite option
OneTrust isn't really a cookie-banner tool that happens to have other features — it's a full privacy/GRC platform (DSAR management, vendor risk, data mapping) where cookie consent is one module among many. It shows up most often where a company already has (or needs) broader privacy-program tooling, not just a banner. For a standalone site that just needs a compliant banner, it's usually more platform than necessary.
What none of the three guarantee
All three are genuinely good at the thing they're built for: showing a compliant banner and recording a decision. None of them automatically verify that every script on your site actually respects that decision after the fact. A GTM container with a misconfigured trigger, an agency-added pixel outside the CMP's script-blocking system, or a Consent Mode v2 signal that never fires correctly — all of these can sit underneath a perfectly well-configured CMP of any of the three, invisible unless something actually checks the live network traffic.
The practical takeaway
Picking a CMP answers "how do we ask for consent." It doesn't answer "does everything on our site actually obey the answer." That's a separate, ongoing check — worth running after any site update, new plugin, or agency change, regardless of which of the three you use.
Bannerproof runs that check automatically against any CMP — it doesn't care which banner tool you use, only what actually happens on the network before and after "Reject." First scan is free.
