Value-aware security framework for enterprise RAG

A security framework for retrieval-augmented generation systems focused on improving trust, reliability, and robustness against retrieval failures and adversarial manipulation. Incorporates trust signals and retrieval quality analysis for enterprise RAG deployments. Under review at HICSS 2026.

• Trust-aware retrieval analysis over enterprise knowledge bases
• Context quality evaluation for generated responses
• Retrieval security mechanisms against adversarial manipulation
• Adaptive defense strategies tuned to enterprise RAG pipelines

Open-source RAG security toolkit

An open-source toolkit for protecting RAG applications against retrieval attacks and prompt injection threats. Ships as a drop-in middleware layer: analyze retrieval context and detect adversarial patterns before they reach the model.

• Retrieval context analysis before generation
• Attack detection mechanisms for common RAG threats
• Security middleware that drops into existing RAG pipelines

Persistent memory for AI coding agents

A memory and checkpointing system for AI coding agents that preserves goals, decisions, blockers, and progress across sessions so an agent resumes exactly where it left off instead of rediscovering state.

• Session checkpointing with goals, decisions, and blockers
• Cross-session context restoration on startup
• Progress tracking to prevent repeated failures across sessions
