Data Leak Prevention for AI
Your AI apps are leaking sensitive data right now.
Sensitive data leaks out through the documents your AI reads, the tools it calls, and the answers it sends back — not just what users type in. Protecto stops every path, without changing how your AI works or what it says.

The Problem
Your AI is sharing sensitive data. You probably don't know where.
Most teams focus on what goes into the AI. But sensitive data can come out through the documents it reads, the tools it uses, and the answers it sends back.
You don't know what sensitive data your AI is using or sharing — and every run is a risk
Your AI reads documents, calls tools, and writes answers — all with sensitive data moving through it. Without any visibility, there is no way to track what was shared, or prove your system is safe when a regulator asks.
Manual filters break your AI's answers — and still miss sensitive data
Simple text-matching rules remove too much, so the AI loses the context it needs to answer well. They also miss sensitive data that's written differently — names spelled wrong, numbers with spaces, or data in unexpected formats.
When a regulator asks which AI calls touched sensitive data, you have no answer
GDPR, HIPAA, and CCPA all require you to show exactly how your AI handles private data. Without a clear log of every time sensitive data was found and blocked, you cannot pass an audit.
How it works
Add one line of code. Protecto handles the rest.
Protecto sits between your AI and your data. Nothing changes in how you built your app.
Detect
Protecto watches what goes into and comes out of your AI — user messages, documents it reads, answers from tools it calls, and its final responses. It scans for over 50 types of sensitive data across 28 languages.
Transform
When sensitive data is found, Protecto replaces it with a safe label like <SSN>...</SSN>. The AI still gets the full context it needs to answer well — it just never sees the real value.
Re‑identify
Before the AI's answer reaches the user, Protecto does a final check. Every piece of sensitive data found and removed is logged — what it was, where it came from, and when. Your compliance team gets a clear record they can export.

Capabilities
Three ways Protecto protects your data.
Protecto works at every stage — when data comes in, when the AI processes it, and when it sends an answer back.
Catch every leak the moment data moves
Protecto checks every piece of data that moves through your AI — what users type, the documents it reads, the tools and APIs it calls, data stored in agent memory, and the answers it gives. It catches sensitive data at every step, not just at the front door.
- Watches all 6 places sensitive data can appear — messages, documents, tools, APIs, memory, and responses
- Finds sensitive data even when it's written differently — misspelled names, numbers with spaces, or unusual formats
- Works in real time, so nothing slips through while your AI is running
Keep AI accuracy intact while removing sensitive data
Most tools delete sensitive data completely — and that breaks the AI's ability to answer. Protecto replaces it with a safe label instead. The AI reads <SSN>...</SSN> instead of the real number, keeps the full context, and answers just as well.
- Labels like [SSN_001] keep the sentence intact so the AI still understands what it's reading
- The original data can be recovered by systems that are allowed to see it — the AI never gets it
- Less than 1% change in AI answer quality, tested across GPT-4 and Claude 3
Block sensitive data before users ever see it
Even when you've cleaned up what goes into the AI, it can still repeat sensitive details in its answer. Protecto checks every response before it reaches the user — so nothing slips through at the end.
- Scans every model output before it reaches the UI or API caller — zero user-facing exposure
- Finds sensitive data even when the AI rephrases it instead of copying it directly
- You choose what happens when something is found — block it, mask it.
Customer story
How one healthcare AI team went from zero control to zero incidents
Challenge: A major health insurance provider was building a RAG-based AI assistant to help subscribers make proactive health decisions. With 50M+ records containing structured and unstructured PHI, two prior data privacy tools failed — each degraded model accuracy to the point of making the AI unusable. Without a fix, the team estimated 6 to 9 months and over $1M to resolve the problem manually.
PHI protected across 50M+ records — recommendation accuracy maintained at scale
“Generic masking tools couldn’t maintain data integrity. Protecto was the only solution that kept the AI accurate while meeting our HIPAA requirements.”

Common Questions
Questions from security and AI teams
Where can sensitive data leak in an AI app?
Sensitive data can show up in many places — what users type, documents the AI reads, answers from tools it calls, data stored across a conversation, logs, and the final answer it sends back. Protecto watches all of these, not just the input.
Does blocking sensitive data break the AI's answers?
No. Protecto replaces sensitive data with a safe label — it doesn’t delete the surrounding text. The AI still sees the full context it needs and answers just as well. Tests show less than 1% change in answer quality.
How long does it take to get started?
Most teams are up and running in under 15 minutes. You add one function call to your code — nothing else changes. No new servers, no changes to your AI model, no rebuilding your app.
Which privacy laws does Protecto help with?
Protecto helps you meet GDPR, HIPAA, and CCPA requirements by keeping a clear record of every time sensitive data was found and blocked. You can export these records to show regulators exactly how your AI handles private data.
Does Protecto work with LangChain, LlamaIndex, and OpenAI?
Yes. Protecto works with LangChain, LlamaIndex, OpenAI, Azure OpenAI, Amazon Bedrock, and Anthropic. You add one function call — that’s it. Nothing else in your setup needs to change.
Can the systems that need to see the real data still access it?
Yes. When a system that is allowed to see the original data needs it, Protecto can give it back. You control which systems get access. The AI itself never sees the real value — only the safe label.
