Customer records, health-related secrets, code-related API keys or any personal information gets copy-pasted while using LLMs — it happens every day, without anyone
meaning harm.
PrivaLLM Prime quietly catches it before it leaves the device and swaps it for a placeholder, so your
team keeps using AI and your data stays yours.
LLMs are amazing for productivity, but every prompt is a two-way door: whatever you type goes straight to the AI vendor. Everyone who uses ChatGPT, Claude, Gemini or DeepSeek ends up exposing some private or confidential data along the way — it's not malice, it's just how these tools get used day to day. Even if your team is careful, mistakes happen. And once it's out there, it's out there. You clicked "I agree" and you have no control over what happens next.
Names, emails and contract details pasted in for a "quick summary" of a support ticket or contract.
Company code and access keys dropped into a prompt to "debug this real quick."
Unreleased projects & business plans, earnings, forecasts pasted in for an analysis prompt.
Individuals sharing private details or unpleasant questions while using work devices.
Two parts, one objective. The Agent runs on every device and does the smart filtering. The Core is where company admins configure the rules and see what's being caught. Nobody has to change how they use AI. Think of it as next-gen DLP, built for a world where the leak happens one prompt at a time.
Installed on every device
Centralized Server / Mini PC
Every message is checked against the rules on the device itself. If it contains sensitive information, that part is replaced with a placeholder before it leaves the device. The AI never sees the original data. When the reply comes back, the placeholder is swapped back for the real value, and the user sees the full answer with the original data.
User chats with any supported vendor with private information.
The Agent checks it against the rules in the background & acts on it.
Any sensitive part is swapped for a placeholder, the message is sent.
When the reply comes back, the real value is restored with the original content.
Admins see what was caught but not the original content itself.
The type of the information without the information itself is what gets sent to the Core, so you can see what was caught (the type of the information) without seeing the content itself. The rules are encrypted on disk, and every device proves who it is with a security certificate.
Every device proves who it is with unique security certificate — not a password that could be copied or faked.
The snapshot of rule configuration stored on each device is encrypted, unreadable if the file is ever copied off.
Only the fact that something was caught leaves the device — never the text itself.
A device offline from the server keeps protecting from its last known rules.
