Sensitive data protection for AI tools

Stop sensitive company data from leaking into AI tools.

Your team uses AI tools every day. Mudcor catches the moment sensitive information is about to be shared with one, and steps in before it leaves the computer. It is built to prevent accidents, which are the overwhelming majority of data leaks, not to police people.

Content never leaves the deviceThe check happens on each computer. The text itself never comes to us.
Protection runs locallyIt keeps working on each computer even if our servers are unreachable.
Never in the way of workChecks finish faster than you can notice, and if anything fails, browsing continues normally.
The everyday risk

The dangerous moment is the ordinary paste.

Most leaks are not attacks. They are a card number, a customer list, or a password pasted into an AI tool by someone just trying to get their work done.

When that happens, Mudcor checks it right there in the browser, before anything is sent. If it finds a card number, customer records, a password, or one of your own watch-words, it removes just those parts, or shows a calm message and lets the person decide, depending on how you set it up. Everything else is left untouched, so people carry on working.

Privacy by design

We never see what your team types.

The things your team types, paste, and upload never leave their computers. Mudcor records only the facts about what happened: when, which AI tool, what kind of information was involved, and the outcome. Not the content itself. We could not show you what someone shared even if you asked, because we never have it.

Set up in minutes. Meaningful from day one.
