What is the Security.txt Downloader & Checker?
security.txt is a small file that tells people how to report a security problem on a website. It is an official standard (RFC 9116) and lives at example.com/.well-known/security.txt.
Our tool looks in both allowed places, downloads the file, and lists each field in a table. It also checks the two required fields, Contact and Expires, and warns you if the file has already expired.
How to use it
- Type or paste the website address, like
example.com. You can also paste the full link to the file. - Press the button. We look for
/.well-known/security.txtin the right place on that website. If it is not there, we also check/security.txt. - Read the simple summary to see what the file says.
- Press Download to save the file, or Copy text to paste it anywhere.
