How to check if your website is secure
To check if your website is secure, look for four things: a secret key in the shipped JavaScript, a database readable without a login, missing security headers, and leaked source or config. All four are visible from your live URL, so a passive scan tells you in about a minute without touching your code.
What to check
- Secret keys in the browser bundle, which anyone can extract.
- An open database, readable without a login.
- Missing security headers, leaving framing and sniffing open.
- Leaked source or config, like a public .env or source maps.
All four are visible from your live URL, in about a minute.
How to confirm it
You do not need to read your code. Everything above is in what the browser already downloads. Plaintext reads your live URL and reports each item worst first, with a fix. A clean scan means nothing was found in what was tested, which is the honest answer, not a guarantee.
Frequently asked
How do I check if my website is secure?
Check for a secret key in the shipped JavaScript, a database readable without a login, missing security headers, and leaked source or config. A passive scan of your live URL reports all four in about a minute, no code access needed.
How can I tell if my website has been secured properly?
Scan the live URL and confirm no secret keys ship to the browser, the database is not readable without a login, security headers are present, and no .env or source maps are public. That covers the openings that matter most.
Check your own app in about a minute. Paste your URL and Plaintext reads the shipped JavaScript, the public endpoints, and the database rules for the exact holes AI code generators leave open. The first scan is free.
