- Designed specifically for RAG architectures: retrieval manipulation and context poisoning attacks are RAG-specific vectors that generic LLM tools do not cover.
- The invisible Unicode Tags checks (RAG-002) and source attribution bypass (RAG-005) detect attacks that evade conventional input filters.
- Compatible with
vamp-orchestratorvia--llm-endpoint: RAG-NNN findings are automatically aggregated into the unified engagement report. - The automatic OWASP LLM Top 10 2025 mapping (LLM01, LLM06, LLM07, LLM08, LLM09) is included in the JSON output with no additional configuration.
