SIM swapping is designed to pass every authentication check a financial institution has in place, making the fraudster appear indistinguishable from the genuine account holder. The institutions able to recognize SIM swapping the earliest are the ones also able to continuously analyze what happens inside the session after a successful login.
The challenge
SIM swapping and device-compromise attacks give fraudsters control of a customer's mobile identity, allowing them to intercept one-time passwords, bypass multi-factor authentication, and reset account credentials. Once control is established, attackers can initiate payments, enroll new devices, or lock genuine customers out entirely. Because access appears legitimate and authentication succeeds as expected, these attacks are difficult to detect until after the fraudster has already made away with the stolen funds.


How we solve for it
Stopping SIM swapping requires looking beyond a successful login. BioCatch correlates behavioral signals such as changes in interaction rhythm, navigation confidence, and session familiarity with device telemetry and authentication context to detect loss of device ownership or external manipulation. These deviations surface even when one-time passwords are intercepted and logins succeed. At the device level, DeviceIQ tracks device identity persistently across sessions, identifying when a new or unfamiliar device environment appears behind a known account, providing an additional layer of detection before fraudulent activity can escalate.

How intent reveals itself
Device identity shift
A new or unfamiliar device profile combined with behavioral changes suggests potential account takeover.
Behavioral discontinuity
Interaction patterns that do not match prior sessions indicate a different operator behind the device.
Location and
network mismatch
Inconsistent IP or location signals suggest the account is being accessed from an unfamiliar or potentially compromised environment.
Synthesized intelligence:
Unified Collection. Continuous Telemetry. Behavioral Sequencing. Predictive Analysis. Real-time Decisioning.
No vendor has ever deployed behavioral intelligence at the scale we've proven possible. We continuously analyze more user sessions (16 billion and counting), collect more signals (3,000 plus), deliver more trusted insights, and protect more digital banking customers (more than half a billion) than any other behavior-centric digital-fraud-prevention solution provider. And we do it in the context of their device, the applications they use, and their transactional tendencies to deliver a trusted and accurate signal for a frictionless and secure customer experience.
