AI Risk Scoring Targets Digital Banking Fraud
On May 20, 2026, National Bank of Canada partnered with Sardine to strengthen digital banking security and improve fraud operations. National Bank selected Sardine after a live evaluation where the platform improved fraud detection and reduced false positives.
The bank will deploy Sardine’s device intelligence and real time risk scoring across retail, commercial, and wealth solutions. Fraud controls are no longer only a back office defense. They now also affect onboarding, payment approvals, customer friction, and trust across the full digital banking relationship. National Bank serves approximately 2.7 million clients globally and reported $606 billion in assets as at January 31, 2026.
National Bank is also leading a $25 million Series C extension in Sardine, bringing Sardine’s total funding to $170 million. That makes this a commercial partnership with one of Canada’s six systemically important banks.

Soups Ranjan, CEO and co-founder of Sardine:
“Sardine was built for banks that need to stop fraud without slowing down their loyal customers,”
False Positives Are A Growth Problem
Banks need to stop attacks without blocking good customers. False positives creates unwanted friction, cost, abandoned journeys, and damages trust. Sardine’s platform combines device intelligence, real time risk scoring, fraud controls, and financial crime automation.
It also uses a fraud consortium, a shared risk network built from activity across many customers and channels. That network spans more than 6 billion profiled devices, 800 million consumers, and 3 million businesses worldwide. For banks, outside risk data can help spot suspicious behaviour faster than internal data alone.
Fraud infrastructure is evolving from rule based screening toward live risk decisions across the customer journey. The optimum systems will reduce losses without punishing legitimate customers.
Agentic Risk Moves Into Banking Operations
Sardine describes itself as an agentic risk platform for fighting financial crime. That means software that helps risk teams detect fraud, score behaviour, and automate parts of fraud and AML operations. National Bank’s release also references agentic AI in the risk and compliance sector.
The need for AI in banking is now well beyond customer service chatbots and internal productivity tools. Some of the strongest use cases are within risk operations, where firms need speed, evidence, and better decisions under pressure.

Joshuah Lebacq, Partner, NAventures, National Bank of Canada's corporate venture capital arm:
“After closely following Sardine’s growth and hearing strong feedback from existing customers, we decided to conduct an extensive evaluation of their platform. The results gave us confidence to make Sardine a strong addition to our financial crime prevention operations and expand our commercial relationship.
We’re excited about the potential of agentic AI, especially in the risk and compliance sphere, and Sardine’s financial crime agents are setting the standard for the category,”
The release didn't disclosure any loss reduction or false positive reduction rates from their evaluation, so keep your eyes out for those metrics in the future.
Talking Point
As AI driven fraud systems enter deeper into banking, will the best institutions win by blocking more bad actors, or by approving more good customers with less friction?
