What We Solve

AI leakage rarely comes from one bug. It comes from too many weak boundaries in sequence.

We look at how sensitive data enters the system, what can retrieve it, how long it lives, what agents can do with it, and how it can escape through logs, outputs, or tool calls.

This matters when teams are moving fast with RAG, copilots, internal assistants, or agent workflows but have not yet hardened the real data paths.

  • Over-broad retrieval that returns more context than the user or agent should see
  • Cross-tenant exposure in indexes, caches, or memory layers
  • Secrets or credentials leaking into prompts, traces, or debugging artifacts
  • Unsafe output handling that re-exposes sensitive internal content
  • Prompt composition problems that mix public and restricted context
  • Tool-using agents that can exfiltrate data through actions or connectors
  • Weak role boundaries between user permissions and AI permissions
  • Retention surprises in logs, prompt stores, analytics, or memory features
  • Vendor and processor uncertainty around where data actually travels
  • Enterprise sales blockers when customers ask how leakage is prevented

If the AI system cannot prove data discipline, trust will eventually fail.

What You Get

  • Data-flow map showing where sensitive content enters, moves, persists, and exits
  • Leakage risk register prioritized by impact, likelihood, and exploit path
  • Boundary design for retrieval scope, tenant isolation, and permission checks
  • Output protection strategy including redaction, escalation, and review points
  • Operational recommendations for memory, logs, analytics, and vendor exposure
  • Evidence pack security, engineering, and procurement can all use

Controls and Delivery

Data Boundary Design

  • Classification-aware routing for prompts, retrieval, memory, and outputs
  • Least-privilege context assembly for user and agent workflows
  • Tenant separation rules for indexes, caches, histories, and shared services
  • Secrets handling and token scope review across tool-connected AI flows

Leakage Prevention Controls

  • Retrieval filters, scoped indexes, and pre-output checks
  • Redaction patterns and controlled disclosure logic
  • Approval gates for sensitive actions or high-risk responses
  • Log and trace hygiene to avoid creating new leak surfaces

Validation

  • Scenario-based leakage tests across user roles and tenant boundaries
  • Prompt and workflow abuse cases for internal and external actors
  • Verification of runtime controls under realistic usage patterns
  • Retest loops after guardrails, routing, or policy changes

Typical Outcomes

  • Cleaner AI architecture for sensitive data environments
  • Better answers to customer security questionnaires
  • Lower internal risk from support, knowledge, and agent tools
  • A workable path to scale AI without constant leakage anxiety
