As payment channels have multiplied, so have the routes open to fraudsters; increasing banks’ potential liabilities. Adoption of real-time payments, Open Banking and digital-led interactions exacerbates these problems. Traditional anti-fraud practices find it all but impossible to efficiently prevent payment fraud. Most rely on hundreds of static, reactive rules that fail to detect new fraud patterns and trigger too many poor hits. Leveraging award-winning 3D artificial intelligence (3D AI) technology, NetGuardians’ platform NG|Screener monitors all of the bank’s payment transactions in real-time catching more fraud with fewer false positives. It identifies suspicious payments coming from social engineering techniques or scams (such as invoice redirection, love scams, CEO-fraud) and ties this in with digital banking fraud indicators (such as eBanking/mBanking sessions redirected by malware, hijacked by hackers or account takeover fraud resulting from identity theft). -
