Secrets & PII Leakage Prevention
Prevent sensitive data leaks through logging, prompts, retrieval, and tool outputs.
// Delivery pattern
This page describes a representative engagement of this shape — how the system is scoped, built, and handed over. Specific figures reflect typical outcomes of the pattern when delivered with the operational discipline described on the About page. Named customer engagements are shared under NDA on request.
Engagement shape
Typical outcomes
- ✓ Reduced leakage risk
- ✓ Safer observability
- ✓ Clear data boundaries
Stack
- — Redaction
- — Data minimization
- — Retention controls
- — Access control
Typical timeline
2–3 weeks
kick-off to handover
Risks & guardrails
- Over-redaction creating observability blind spots — calibrate rules with the ops team
- RAG retrieval scope too broad — define document boundaries per use case before setup
Problem
Leaks often happen through “normal” engineering: logs, traces, prompts, retrieved documents, and tool outputs. Teams want observability, but accidentally store PII or secrets — creating compliance and security issues.
Solution
We implement practical data-boundary controls:
- Redaction in logs and traces (PII/secrets)
- Prompt and context minimization
- Retrieval boundaries and provenance for RAG
- Access control and retention policies
What we deliver
- Data classification and boundary map
- Redaction pipeline + safe logging defaults
- RAG guardrails: document scope, retrieval validation, provenance
- Secure incident workflow and audit documentation
Measurement (typical)
- Reduced sensitive payloads in telemetry
- Clear retention periods and access controls
- Repeatable audits of “what gets stored where”
CTA
If you need observability without leakage, we’ll set safe defaults and data boundaries end-to-end.
