(Financial Risk and Compliance)

The financial ecosystem has been facing substantial changes. Financial institutions are struggling to meet the requirements of regulators, and current anti-money laundering solutions are falling short of their needs. At the root of financial crime are felonies involving drugs, human trafficking and terrorism. 

But there’s hope! Artificial intelligence and machine learning offer the promise to help effectively detect criminals. The Sentinels team is building a cutting-edge transaction monitoring platform to help financial institutions meet pressing regulatory requirements, improve compliance workflow, maximise their customer experience, and balance the fight against financial crime.
