Trust is
Computed.

Sentinel establishes absolute trust at the edge. We bypass legacy CAPTCHA friction and probabilistic guessing, replacing them with cryptographic intent verification and structural telemetry.

// ABOUT THE ENGINE

We built the trust layer the internet was missing.

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.

Node.js / ExpressCOPY
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' });
}
Next.js Edge MiddlewareCOPY
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');
}
V2 Policy DSLCOPY
// Dashboard-configurable rules
const config = {
  vpn_action: 'challenge',
  datacenter_action: 'block',

  exempt_server_requests: true
};
// POST /v2/evaluate → live verdict
// WHY SENTINEL

Not another WAF. Not another CAPTCHA.

ZERO USER FRICTION

No puzzles. No image grids. No interruptions. Humans pass silently. Bots get annihilated structurally.

SUB-50MS VERDICTS

In-memory ASN matrices, LRU-cached intelligence, and a Redis-distributed velocity engine. Speed is our architecture.

API-FIRST DESIGN

Single POST endpoint. Structured JSON verdicts. Works with any language, any framework, any infrastructure stack.

GDPR NATIVE

Stateless, no PII stored. Privacy mode redacts all granular geodata. RFC1918 local IPs auto-whitelisted.

The Intelligence Perimeter
Behavioral Work Tokens (BWT) & Intent Cryptography
When abstract heuristics fail, we inject a highly specific, computationally intensive SHA-256 challenge mapped directly to the User's physical DOM events. Human intent is mathematically proven through structural complexity—bots stall instantly.
VERDICT: CHALLENGE ACTION: require_pow PREFIX: c8a9fc... DIFFICULTY: target_level_3
Global Threat Pub/Sub
Connected directly to a Redis backbone. When a single Sentinel node isolates structural abuse, the payload signature and ASN are broadcast horizontally to every edge node globally in under 2ms.
Absolute "Humans Only" Mode
A zero-tolerance logic gate. The V2 Engine instantly discards math-based risk scores, enforcing an unyielding Boolean requirement: Verified Residential Context AND Computated Behavioral Work. Anything else is annihilated.
High-Velocity DSL Evaluation
Deploy granular security rules natively from the dashboard using our minimal, regex-compiled Domain Specific Language. Evaluated locally on the Edge in <5ms.
// Synced directly via Supabase / Redis Cache const tenantRules = [ "IF signal == 'VERIFIED_BOT' THEN ALLOW", "IF signal == 'HIGH_VELOCITY' THEN BLOCK" ]; const override = this.evaluateRules(tenantRules, rawSignals); if (override) return override;
Economic Resistance
Sentinel scales from hobbyist infra to enterprise-grade API economies.
Pay for authority, never for friction.
