NULLO - Scan anything. Stay private.

Three ways to scan

Give NULLO anything

No matter what format your data is in, NULLO can read it and find the risks.

Drop in source code, config files, environment variables, or any raw text. NULLO scans every line.

Provide any public web address. NULLO fetches and analyzes the page for trackers, exposed data, and insecure headers.

Upload a .env, .json, .yaml, .pdf, or any document. NULLO reads it and reports every risk it finds.

Process

Paste text, enter a URL, or upload a file - any format, any size.
