Sentinel is a deterministic behavioral trust API. We do not guess. We do not score probabilistically. We analyze structural network data and return a mathematically-grounded verdict in under 50 milliseconds.
CAPTCHAs became obsolete the moment AI could solve them faster than humans. WAFs became brittle the moment attackers learned to rotate IPs. Rate limiters became hostile the moment legitimate users shared infrastructure.
We spent years watching these hacks compound into systems that simultaneously failed against real attackers while punishing real users. Sentinel is the answer we wished existed.
Our approach is radical in its simplicity: every IP address is a compressed packet of structural truth about its origin. We decode that packet, cross-reference it against real-time ASN topology and behavioral entropy matrices, and return a verdict that no CAPTCHA solver, VPN rotation, or residential proxy farm can fake.
Most security systems gather evidence, delay, and then guess. Sentinel decodes. The ASN, the carrier type, the infrastructure class, the velocity signature — these are deterministic facts, not probabilistic guesses.
We made a conscious trade-off: Sentinel's FastPath runs in under 50ms with no external API call. Deep enrichment runs async and never blocks your users. You get a real verdict, at wire speed, every time.
Sentinel V2 is a ground-up rebuild of the original RiskSignal intelligence engine, redesigned for multi-tenant deployments, enterprise SLAs, and deterministic behavioral cryptography.
One API key. Five minutes. 92% fewer automated attacks from day one.
