Security controls are integrated into platform behavior, not bolted on after deployment. The focus is scoped access, sensitive-data discipline, event trust, and reviewable operations.
Every callback is signature-verified, freshness-checked, and replay-deduplicated before it touches money state. The pattern is enforced by the contract, not left to integrator memory.
const signature = req.headers["zentra-signature"];
const timestamp = req.headers["zentra-timestamp"];
if (!verifyHmac(payload, signature, secret)) {
return res.status(401).end(); // reject before state mutation
}
if (isStale(timestamp) || seenBefore(event.id)) {
return res.status(200).end(); // replay converges to no-op
}enforced posture
Role-scoped authentication and tenant-aware authorization boundaries.
Security controls for transport, storage, and operational handling.
Operational pathways for anomaly detection and response execution.
Enterprise teams want to understand access, sensitive data, event verification, and incident response before launch. For production onboarding, request a formal security architecture review — the evidence is already structured for it.
Who can act, on what, in which tenant — enforced by role and scope boundaries rather than convention.
Secrets, tokens, PAN, CVV, and full identity records never reach logs. Sensitive fields stay masked in operator and support surfaces.
Callbacks are signature-verified and freshness-checked before any state mutation. Unsigned or malformed events are rejected outright.
Escalation follows runbooks, and every incident leaves a reviewable trace for post-incident hardening.
