Everything about vendors, in a single control panel
TCF Vendor Explorer is a free platform that gives you a complete view of the vendor ecosystem: discover what each one declares, which markets it operates in, for what purposes, and which mechanisms it uses to transfer data to non-European countries.
More visibility, more control and better decisions: analyze the ecosystem, discover new vendors, filter the most relevant ones and speed up decision-making.

The vendor ecosystem has grown faster than the ability to control it
Thousands of providers advertise through the TCF, but few teams know how many are actually active.
Undeclared vendors
Active providers that aren’t properly listed in the TCF, or that operate without truly being signed up to the framework.
Exposure to the DPA
An outdated vendor list is one of the most common reasons for review by data protection authorities.
Slower page load
The more vendors declared, the longer the page takes to load and the CMP takes to register consent.
Save time with a single panel
Easily download your vendor queries and their attributes for better analysis: all in a single panel, with export options.
Having a thousand vendors in your CMP isn’t transparency for the user. It’s noise. — That’s why TCF Vendor Explorer exists
