How does TILDA help financial institutions combat fraud more effectively?
Fraudsters rarely operate within the boundaries of a single bank, organisation, sector or country. Consequently, the information needed to detect and stop fraud is often fragmented. The victim's bank sees a suspicious payment, whilst another institution sees the account into which the money is transferred. Other parties may hold signals about what preceded the fraud. With TILDA, Isabel is developing a new, neutral and secure infrastructure that helps financial institutions detect fraud more quickly, investigate it jointly and share relevant fraud signals safely.
TILDA will take a prominent place within Febelfin's sector-wide fraud action plan(opens in a new window), developed at the request of Rob Beenders, Belgian Minister for Consumer Protection, Social Fraud Prevention, Persons with Disabilities and Equal Opportunities. The platform also helps financial institutions prepare for future European obligations around fraud prevention and information sharing under the Payment Services Regulation (PSR).
Why collaboration is essential
Fraud often follows a chain of events. A victim may first be approached via a fraudulent message, a phone call or an advertisement. A payment is then made to an account held at another financial institution.
When each party involved can only see part of that chain, building a complete picture quickly is not always straightforward. By bringing relevant information together in a secure and structured way, institutions can recognise connections more quickly and take more targeted action.
Tackling fraud starts by speaking the same language. We need to know not only that fraud has taken place, but also what type of fraud it involves and how the fraudster operated.

A common language for fraud
To work together effectively, parties must also be able to describe fraud consistently. Today, organisations do not always use the same terminology when recording fraud cases. This makes it harder to compare cases, identify patterns and accurately map the full scale of the fraud.
TILDA therefore provides a standardised fraud taxonomy and a common framework for describing fraudsters' modus operandi. The fraud taxonomy describes what happened, such as phishing, impersonation fraud, or investment fraud. The modus operandi describes precisely how the fraudster carried out the act.
This helps financial institutions classify cases more consistently, link related fraud incidents and identify recurring methods more quickly.
Conducting fraud investigations jointly
TILDA supports joint fraud investigations between the financial institutions involved. One of the first practical applications is the tackling of money mule accounts.
When a financial institution identifies a suspicious payment, it can use TILDA to request that the beneficiary's institution investigate the relevant account. If that account is confirmed as a money mule account, other participating institutions can be sent a verified fraud signal. They can then check whether related transactions or accounts appear within their systems.
TILDA shares information, not automated decisions. Each financial institution remains responsible for its own risk assessment and for any actions taken in relation to a customer or transaction.
Only when institutions can share fraud information quickly, securely and in a standardised way can they identify connections that would not be visible from within a single organisation.

A platform for the sector, built for the future
TILDA is being developed primarily for financial institutions, with the support of Isabel's shareholders: Belfius, BNP Paribas Fortis, ING Belgium and KBC. The platform is open to all payment service providers in Belgium.
The ambition extends beyond the financial sector. Isabel is exploring collaboration with, amongst others, telecom operators, digital platforms, digital identity providers and the Centre for Cybersecurity Belgium. These parties can contribute additional signals or assist in identifying and taking down fraudulent websites, phone numbers and other criminal infrastructure.
Fraud cannot be tackled by any single bank, technology company or public authority acting alone. TILDA brings the relevant parties together in a neutral and trusted environment, enabling them to exchange information faster and collaborate more effectively.

The TILDA test environment has been available since 26 June 2026. A first pilot with participating financial institutions in a production environment is planned for the fourth quarter of 2026. In doing so, Isabel aims to turn collaboration in fraud prevention into an everyday operational practice and help build a more connected and resilient financial ecosystem.
