Use AI at work without leaking company data.

Staff paste customer details, contracts and spreadsheets into ChatGPT every day. Nesgate hides the sensitive parts before anything is sent, so your company keeps the benefits of AI without the risk.

Animated example in three steps. One: a message typed into an AI chat contains an email address, a card number and an access key; Nesgate highlights them as they are typed and replaces them with labels before the message is sent. Two: a photo of a sample identity card is attached; Nesgate blacks out the ID number, name, date of birth, address, face photo, signature and machine-readable lines before the image is sent. Three: a payroll spreadsheet is attached; names, ID numbers and bank accounts are replaced with labels and the file stays a spreadsheet.

A typed message. The email address, card number and access key are spotted as they are typed and replaced with labels. The AI still understands the request.

Everything staff send to AI is checked first

Most leaks are honest mistakes: someone wants a quick answer and pastes in more than they should. Nesgate hides the sensitive part and lets the rest through, so the work still gets done.

Typed text

Words and numbers people type or paste

Passwords, bank and card numbers, ID numbers, email addresses, phone numbers and your own project names are hidden and replaced with a label such as “[CARD_1]”. The AI still understands the question.

Files

Documents people attach

Contracts, offer letters, payroll sheets and other Word, Excel, PowerPoint and PDF files are sent as a copy with the sensitive details hidden. A spreadsheet stays a spreadsheet.

Photos

Photos, screenshots and ID cards

Text inside pictures is read and the sensitive parts are blacked out, including the photo and signature on ID cards. Nesgate checks the result again so nothing readable is left.
