What does Basis Technologies do?
What Basis Technologies is
Basis Technologies, formerly known as Centro, is an omni channel programmatic advertising platform that combines a demand side platform (DSP), an ad server, planning and workflow tools. Brands and agencies use it to plan, deliver and measure display, video, native, search, social and connected TV campaigns from a single interface.
What data Basis collects
Basis sets advertising cookies, captures the IP address, user agent, page URL, conversion events and audience segment membership through a tracking pixel installed on advertiser sites. The platform exchanges identifiers with downstream supply side platforms during real time bidding.
GDPR and ePrivacy implications
Cookie storage triggers Article 5(3) of the ePrivacy Directive and requires prior consent. Programmatic profiling across multiple channels and the IAB TCF v2.2 signal must be passed through the entire chain, with the publisher and the advertiser remaining responsible for the consent collection.
Consent requirements
Block the Basis pixel until marketing or advertising consent has been collected. Pass a TCF v2.2 TC string. Honour withdrawal by stopping events and clearing cookies set by Basis or its partners.
Data transfers
Basis Technologies is a US company. Transfers from the EEA require certification under the EU US Data Privacy Framework or Standard Contractual Clauses with a transfer impact assessment that addresses the FISA 702 risk surface for US adtech operators.
Practical compliance steps
Sign a Data Processing Agreement, document Basis Technologies and its sub processors in your record of processing activities, run a DPIA, gate the pixel through your CMP, restrict events to those needed for measurement and offer a user level opt out.
Basis Technologies and the GDPR
Basis Technologies is classified as “Marketing”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy.
- Legal basis
- Article 6(1)(a) GDPR (consent) and Article 5(3) ePrivacy Directive for cookie storage and reading
- Risk level
- high
- Applicable regulations
- GDPR, ePrivacy Directive, PECR, IAB TCF v2.2
Impact assessment (DPIA)
A DPIA is required because Basis combines cross site profiling, programmatic auctions across multiple channels and US transfers, all factors that meet the EDPB criteria for high risk processing.
