Tenant Isolation Patterns for Multi-Tenant LLM Infrastructure
When a single LLM endpoint serves multiple internal departments or external clients, tenant bleed is not theoretical — it is an architectural inevitability without explicit isolation.
PII Handling in Retrieval-Augmented Generation Pipelines
RAG pipelines introduce a new PII surface: the retrieved context. We examine where personal data leaks into retrieved chunks and how entity-level redaction must handle partial-name and indirect identifiers.
EU AI Act Readiness Checklist for Enterprise Deployments

Audit Log Design for AI Systems: What Auditors Actually Ask
After sitting through three enterprise compliance reviews, we catalogued the exact log fields auditors request — and which ones most teams are missing.
Prompt Injection Defense in Production LLM Systems
Prompt injection remains the top exploitable surface in enterprise LLM deployments. We break down detection strategies, proxy-layer interception, and log signatures that distinguish genuine jailbreaks.
