Sentinel establishes absolute trust at the edge. We bypass legacy CAPTCHA friction and probabilistic guessing, replacing them with cryptographic intent verification and structural telemetry.
Sentinel was engineered by infrastructure security veterans who were tired of watching CAPTCHAs fail, WAFs misfire, and rate limiters punish legitimate users. We took a different approach: deterministic trust from structural data alone.
Every connection to your API is a packet of raw infrastructure intelligence — ASN topology, behavioral entropy, carrier-level provenance. We parse it all in under 50ms and return a single, mathematically-grounded verdict.
const result = await sentinel.check(req.ip, { profile: 'signup', user_agent: req.headers['user-agent'] }); if (!result.allow) { return res.status(403) .json({ action: 'blocked' }); }
export async function middleware(req) { const ip = req.headers.get( 'x-forwarded-for' ); const trust = await Sentinel.evaluate(ip); if (trust.verdict === 'BLOCK') return Response.redirect('/banned'); }
// Dashboard-configurable rules const config = { vpn_action: 'challenge', datacenter_action: 'block', humans_only: true, exempt_server_requests: true }; // POST /v2/evaluate → live verdict
No puzzles. No image grids. No interruptions. Humans pass silently. Bots get annihilated structurally.
In-memory ASN matrices, LRU-cached intelligence, and a Redis-distributed velocity engine. Speed is our architecture.
Single POST endpoint. Structured JSON verdicts. Works with any language, any framework, any infrastructure stack.
Stateless, no PII stored. Privacy mode redacts all granular geodata. RFC1918 local IPs auto-whitelisted.
