What Onesecondbefore CMP is
Onesecondbefore CMP is a consent management platform from Onesecondbefore CMP in Amsterdam, The Netherlands. It manages consent for websites and mobile apps, with interfaces covering purposes, legitimate interests, special features, and vendors. The maker says it supports IAB TCF 2.2 and is accredited by the IAB, and integrates Google Consent Mode v2 by mapping TCF choices to Google signals. Consent records can be stored in a customer’s own data lake, while analytics, profiles, and consent can be handled in one place. A central consent page can serve multiple sites and return visitors with consent information. Websites can load the CMP through the JavaScript library and osb-cmp.min.mjs module, or use a REST API configured by the maker. Android and iOS SDK source code is released under the Mozilla Public License. The free plan is available, with other pricing on request.
Who it suits
