Your data stays in India. Always.
CrewCheck inspects AI traffic without persisting prompts, training on your data, or creating unauditable evidence. Built for teams that answer to DPDP, RBI, and SEBI.
Latest production measurement: sub-100ms added gateway overhead at P95. Total round-trip latency depends on your chosen upstream LLM provider.

Security Architecture
Six pillars of trust
Every design decision in CrewCheck starts with one question: how do we protect customer data while still delivering governance value?
Zero Persistence
Raw prompts exist only in RAM during inspection. Nothing is written to disk, stored in a database, or logged. The value is gone within a millisecond.
India Data Residency
All processing happens on Railway (Asia-Southeast) and Supabase (Indian region). Your data never leaves India's jurisdictional boundary.
Tamper-Evident Logs
Audit logs are hash-chained. Any modification is cryptographically detectable during verification — no silent edits possible.
Deterministic Detection
PII detection uses regex, Verhoeff checksums, and word-digit normalization. No black-box AI — your security team can inspect every rule.
Key Isolation
Your API keys are used only for your LLM workload. Guardrail evaluations run on CrewCheck's own keys and infrastructure, at our cost.
VPC / Air-Gap Option
For zero-trust requirements, deploy CrewCheck inside your own VPC. No raw prompt ever leaves your private network.
Latency Methodology
What we measure, and what we do not
CrewCheck reports gateway overhead separately from upstream model time. The number we publish is the internal request path inside CrewCheck: auth, app and policy resolution, PII scanning, policy evaluation, and response serialization. Provider latency is real, but it belongs to your chosen LLM vendor and region.
Current production result
81ms P95 gateway overhead on May 11, 2026, measured on the live production gateway.
Buyer-safe claim
We describe this as sub-100ms added gateway overhead at P95. We do not fold provider time into that claim.
Latency SLO
CrewCheck currently targets gateway overhead under 250ms at P95 during business hours.
How It Works
What happens to your prompt
Prompt arrives at CrewCheck gateway
Your app sends the request to CrewCheck's Indian-resident endpoint instead of directly to OpenAI/Anthropic.
In-memory PII inspection
Deterministic detection (regex + Verhoeff checksums) identifies Aadhaar, PAN, UPI, IFSC values. No disk writes. No database storage.
Redaction & policy enforcement
Detected PII is replaced with safe tokens. DPDP policy packs enforce purpose limitation and consent requirements.
Clean prompt forwarded to LLM
The redacted prompt is sent to your chosen provider using your API key. The provider never sees raw PII.
Audit record created
A hash-chained log entry records the action taken — never the raw value. The original prompt is discarded from RAM.
