Why Organizations Trust Check Vero
Early-access design partners and a security-first architecture.
Invite-only pilots with government and enterprise teams. Tight feedback loops, measurable outcomes.
Raw numbers are never stored (E.164 → Argon2id → SHA-256 + pepper). Encryption in transit/at rest. Fail-closed paths.
Designed to meet SOC 2 Type II controls. Role-based access and comprehensive audit logs.
Targeting 99.9% uptime with rate limiting: configurable defaults (e.g., 5 rps, burst 10) and sub-100ms responses.
Demo Statistics (Simulated)
SimulatedDemo data for illustration; live metrics enabled during pilots.
Real-time style demo metrics. Aggregated sample data for preview purposes.
* Sample data. Production metrics will be published after public launch.
Interactive Spoof Demo
Test our SVC (Signaling Verifier) service with different scenarios to see how cryptographic nonces prevent replay attacks and rate limiting stops abuse.

Safety Reporting & Rewards
Community-driven scam detection with platform credits incentives for protecting others from phone fraud and spoofing attacks.
Users can report suspicious phone numbers with evidence and context for community verification.
Credit-based safety reporting system for verified reports that help protect the community from phone scams (optional feature, under review).
Multiple community members validate reports before numbers are flagged in the registry.
Proactive identification of scam numbers before they can harm more potential victims.
How It Works
A credit-incentivized system for community-driven scam detection and prevention.
Report Suspicious Numbers
Submit phone numbers with evidence of scam activity or spoofing attempts.
Community Verification
Other users validate reports through a consensus mechanism before flagging.
Earn Platform Credits
Credit-based safety reporting system for verified reports that help protect the community from phone scams (optional feature, under review).
This feature is currently in the design phase. Validation mechanisms and community structures are being developed with input from security experts and early access partners. Credits have no monetary value and are only used within the platform to prioritize verification workloads.
