AI data loss prevention for LLM workflows.
Purpose-built AI DLP that detects PII, masks sensitive entities, and prevents document leakage across ChatGPT, Copilot, and API workflows. Traditional DLP was not built for AI — PromptWall is.
Why traditional DLP fails for AI
Traditional DLP tools monitor file transfers, email attachments, and clipboard operations. They have zero visibility into AI prompt content — sent via HTTPS to external providers, often through browser interfaces that bypass network-level inspection entirely.
How AI DLP works
PromptWall intercepts AI prompts before they reach the provider and runs entity recognition, pattern matching, and document similarity analysis. Detected sensitive data can be masked, flagged, or blocked — all governed by tenant-level policy.
