AI Data Loss Prevention
AI Data Loss Prevention (DLP) for ChatGPT, Claude, and Copilot
Traditional data loss prevention was built for files and email. It never sees the chat box, which is exactly where your team now pastes customer lists, API keys, and source code. StileAI is DLP built for AI: it inspects every request to an AI tool and stops sensitive data before it leaves your company.
Why classic DLP misses AI
Your firewall, CASB, and email DLP watch attachments, uploads, and outbound mail. An employee pasting a spreadsheet into ChatGPT does none of those things, so nothing in your stack records it or stops it. The data is gone the instant they hit enter, to a server you do not control, sometimes into a model you will never see.
How StileAI does AI DLP
StileAI sits in the path between your team and the AI tools they use, and gives every request one of three outcomes:
- ▸ALLOW: safe and in-policy, sent straight through with no friction.
- ▸HOLD: sensitive, held for an admin to approve before it can be sent.
- ▸BLOCK: against policy, stopped before it ever leaves the browser or client.
What it detects
Detection runs in layers so disguised and reworded leaks are still caught, not just tidy keywords.
- ▸Secrets: API keys, passwords, tokens, and private keys, including novel formats caught by entropy and shape.
- ▸Personal data (PII): emails, phone numbers, national IDs, and valid payment-card numbers.
- ▸Customer and client records, financial data, and legal documents.
- ▸Source code and proprietary configuration.
- ▸Meaning-based detection for paraphrased, unlabeled, or non-English content that pattern matching misses.
Audit-ready by default
Every decision is logged, who sent what, which policy caught it, and the outcome, with sensitive values redacted. The categories map to SOC 2, GDPR, HIPAA, PCI-DSS, and ISO 27001, so an AI leak you stopped becomes evidence you can hand an auditor.
Frequently asked questions
What is AI DLP?
AI data loss prevention checks the prompts and requests your team sends to AI tools and blocks or holds anything sensitive before it leaves, the same idea as classic DLP but built for the chat box and AI APIs that traditional tools cannot see.
Does StileAI replace my existing DLP?
No. It covers the gap your existing DLP cannot: outbound requests to AI tools. It runs alongside your firewall, CASB, and email DLP.
Does my data get stored?
Content that is blocked or held is never stored, only the decision and category are logged, with sensitive spans redacted. Your AI provider keys pass straight through and are never saved.
Which AI tools does it cover?
ChatGPT, Claude, and Gemini in the browser via an extension, plus Cursor, Claude Code, and any OpenAI- or Anthropic-API app via a one-line gateway setup.
