Blind.
Legacy systems look at one transaction at a time. They evaluate a single sender and receiver in isolation.
Coordinated fraud activity, account abuse, velocity patterns, device overlap, and AML signals can slip past when each transaction is reviewed alone.
Structural.
We see the full transaction context. Account behavior, device overlap, payment velocity, counterparty patterns, and unusual flow paths.
Before funds clear, Sent1nel checks whether the payment fits the account, the device, the counterparty, and the behavior that came before it.
Latency vs Depth.
Solved.
Stop high risk transactions in milliseconds. Review the full risk picture overnight. Both, without trade offs.

Real Time Decisions
Every payment is evaluated against fraud vectors, account behavior, device and session signals, counterparty activity, and previous transaction context before funds clear.
Forensic Review
Every flow is replayed overnight. Forensic models learn from historical behavior and feed better risk decisions back into the real time layer.
One Event Stream
One event stream captures every transaction and routes it to both real time decisioning and forensic review, without delay.
What Sent1nel
assesses
in real time.
Account &
Counterparty Context
Understand who is transacting, how accounts relate, and whether the relationship fits previous behavior.
Payment Flow
Behavior
Detect unusual movement patterns, repeated transfers, rapid pass throughs, velocity changes, and unexpected payment paths.
Account Activity
Signals
Monitor account behavior, access patterns, transaction timing, locations, and available session or device signals.
Where Sent1nel
works.
-
01 / Real Time Transaction Decisions
Assess, approve, review, or block transactions before funds clear.
-
02 / Fraud Vector Monitoring
Detect linked account activity, device and session overlap, velocity risk, counterparty anomalies, and unusual payment paths.
-
03 / Forensic Review & AML Support
Replay events, explain risk decisions, support AML workflows, and give fraud, risk, operations, and compliance teams an auditable view of what happened.
The transaction
is just a symptom.
The network
reveals the risk.
Stop chasing individual anomalies.
Sent1nel turns transaction context into real time risk decisions.
