Key Benefits
Protect growth and experience for real users
Validate real human history before sending an OTP. Block artificial traffic and premium-rate exploitation at the source to prevent unnecessary authentication costs.
Use tenure, ownership continuity, and authentication history to distinguish humans from automation — protecting downstream models and enabling smarter decisions.
Stop automated abuse early while allowing legitimate users to move through signup, login, and high-value flows without unnecessary step-ups or blanket friction.
Use Cases
Precision Bot Control Across Critical Flows
Block non-human OTP requests before messages are sent — preventing SMS toll fraud and runaway authentication costs.
Detect low-tenure and newly provisioned numbers to stop repeat re-entry and prevent bad actors from cycling through new accounts.
Continuously measure phone-level identity strength to flag scripted accounts lacking tenure or authentication history.
Business Impact
For Your Customers and Your Bottom Line
Eliminate SMS pumping and OTP abuse to stabilize spend and avoid sudden cost spikes
Make durable, identity-backed decisions that reduce false positives and stop bots earlier
Keep real customers moving through critical flows while blocking bots before they degrade funnels
How it Works
How Prove Human Assurance works to create
a seamless, secure experience
Why Prove?
Why Prove brings confidence to every interaction
Prove validates the phone number itself as a real human authenticator — not surface signals like IP or device fingerprints — enabling deterministic separation of humans from automation
Built on 2.5B+ known identities, Prove connects devices, keys, authentication history, and longitudinal phone tenure into a persistent identity foundation bots can’t replicate
Prove’s Global Fraud Policy transforms identity intelligence into consistent, real-time decisions — enabling precise bot blocking without fragmented rules or regional blind spots
“SMS pumping has quickly become one of the most costly and overlooked fraud vectors—where bots generate massive volumes of fake verification requests, driving up messaging costs and straining infrastructure. Without strong identity signals, businesses are left paying to engage attackers instead of real customers.”
