Pseudonymizing sensitive data for LLMs without losing context

AI Analysis
●●SolidBig BrainSolve My Problem
Proxy pseudonymizes sensitive data so LLMs don't hallucinate like they do with regex.
Strengths
- •Prevents LLM syntax hallucinations by keeping pseudonyms structurally valid.
- •Transparent proxy architecture means zero changes to existing agent prompts.
- •Open-sourcing the DLP layer builds trust for security-sensitive deployments.
Weaknesses
- •Blog post focuses heavily on selling the broader Ghost Analyst SaaS platform.
- •Unclear if the open-source proxy supports providers beyond Anthropic's Claude.
