National Bank of Canada has announced a multi-year partnership with Sardine to improve digital banking security and fraud operations. The bank will use Sardine’s device intelligence and real-time risk scoring across retail, commercial, and wealth services after an evaluation showed improved fraud detection and fewer false positives.

National Bank of Canada is partnering with Sardine, a financial crime prevention platform, to strengthen its digital banking fraud detection and risk operations.

The multi-year agreement will see National Bank deploy Sardine’s device intelligence and real-time risk scoring across its retail, commercial, and wealth services. The bank said the decision followed an evaluation in which Sardine improved fraud detection while reducing false positives, helping limit unnecessary friction for legitimate customers.

False positives are a significant issue in fraud prevention. When legitimate transactions are incorrectly flagged as suspicious, customers may face delays, account interruptions, or additional verification steps. Banks must balance preventing fraud with ensuring that regular customers can continue banking without unnecessary disruption.

Sardine describes its platform as an agentic risk system designed to help financial institutions detect financial crime in real time, prevent AI-driven attacks, and automate fraud and anti-money laundering operations. Its technology includes device intelligence, risk scoring, fraud consortium data, and automation tools intended to support risk and compliance teams.

National Bank of Canada, one of the country’s six systemically important banks, serves approximately 2.7 million clients globally. The bank said Sardine’s platform will become part of its financial crime prevention operations as digital banking threats continue to evolve.

The announcement also includes a further investment by National Bank. The bank is leading a US$25 million Series C extension round in Sardine, bringing Sardine’s total funding to US$170 million.

The partnership reflects a broader shift in the financial sector toward faster, data-driven fraud detection systems. As scams, account takeovers, synthetic identities, and AI-enabled attacks become more sophisticated, banks are increasingly looking for tools that can identify suspicious behaviour without disrupting legitimate customers.

For Canadian banking customers, the announcement is another sign that fraud prevention is becoming a major operational priority for financial institutions. While technology can help detect suspicious activity, customers should still remain cautious when receiving unsolicited calls, texts, emails, or account alerts claiming to come from a bank.

Banks generally warn that customers should not provide passwords, PINs, one-time codes, or security credentials to anyone who contacts them unexpectedly. Customers who notice suspicious activity should contact their financial institution directly using a trusted phone number or official banking app.
