A real-world example

Which accounts will experience an unauthorized login in the next 14 days?

ATO is the fastest-growing fraud vector — up 72% year-over-year. Current rules trigger after 10 failed logins, but by then the attacker has already tried credential-stuffing. Banks need to predict which accounts are being targeted before the attack succeeds. Average ATO costs $12K per incident. At scale, 500 prevented ATOs = $6M saved.

How KumoRFM solves this

Graph-powered fraud intelligence

Kumo analyzes the relational graph of login events, device fingerprints, IP networks, and account relationships. When Account A002 shows login attempts from IPs that have attacked other accounts in the network, Kumo detects the cross-account signal that single-account rules miss.

Bottom line: Preemptive MFA step-up on 3% of accounts prevents 60%+ of ATO losses. Average ATO costs $12K per incident — preventing 500 saves $6M.
