Silent verification through carrier signals. Zero friction for legitimate users. Invisible to attackers. The foundation of the Trust Stack.
Traditional verification methods are fundamentally broken.
of 2FA bypasses use SIM swap or SS7 attacks to intercept OTPs before the user sees them.
of users will enter their OTP into a convincing phishing page. Real-time forwarding defeats time limits.
increase in account takeover attacks since 2020. Credential stuffing meets scalable automation.
Why send a code that can be intercepted when the carrier already knows who owns the phone? SilentOTP uses carrier signals to verify identity without any user action.
Zero user friction • No SMS codes required
Every verification request is analyzed across six independent signals. Attackers can't fake them all.
Detect if the SIM was recently swapped
Match device characteristics against known patterns
Detect brute force attempts with rate limiting
Flag impossible travel or location mismatches
Verify the number is on the expected carrier
Validate number type, age, and reputation
Each signal contributes to a weighted trust score. You set the threshold. High-risk actions require higher scores.
The score is returned with every verification result, giving you granular control over your risk policy. Step-up authentication only when needed.
