Madrid/Barcelona, 15 June 2026.
FrauDfense, a company owned by Banco Santander, BBVA and CaixaBank, today announces the go-live of FrauDfense Check, its first operational service. This initiative highlights the pioneering and innovative role of the three institutions in promoting sector-wide collaboration models, positioning the Spanish financial industry as an international benchmark in fraud prevention.
FrauDfense has developed an advanced, high-performance technology platform designed to operate in line with the most demanding banking standards. Building on this foundation, the company is launching a service aimed at preventing fraud befare it occurs through the secure exchange of information between financial institutions.
Opening to other financial institutions
In this context, FrauDfense is opening participation to the entire Spanish financial sector, making the service available to new institutions and marking a milestone in the collective fight against financial crime.
The addition of new participants will expand the reach and effectiveness of the collaborative model, strengthening customer protection and reinforcing a robust and coordinated response to financial crime.
A service tested in real use cases with proven results
Over the past year, Banco Santander, BBVA and CaixaBank have tested FrauDfense Check, applying it to multiple use cases relevant to day-to-day banking operations, including customer onboarding, product contracting, credit transfers, instant payments, Bizum payments and card transactions.
As a result of this pilot, the capacity to prevent fraud worth millions of euros was demonstrated, highlighting the value of sector-wide collaboration and shared intelligence as key levers in addressing new fraud typologies.
A collaborative ecosystem to fight financial crime?
FrauDfense has built a collaborative ecosystem in which financial crime leaders and experts from majar Spanish financial institutions exchange information, analyse common patterns and design and promete joint actions against emerging threats.
This collaborative model also provides key support in anticipating and facilitating compliance with the upcoming regulatory requirements under the European Payment Services Regulation (PSR), currently in the approval phase, which strengthens the obligation for payment service providers to share fraud-related information. The FrauDfense approach enables this to be done in a structured, secure and privacy-preserving manner, raising the overall level of protection across the financial system.
