What it catches

The 7 things small sites get wrong

Most breaches don't come from elite hackers, they come from boring, fixable mistakes. This skill checks for all of them.

🔓

Missing / broken HTTPS

No SSL, expired certs, no HTTP→HTTPS redirect, outdated TLS, and missing HSTS.

📋

Weak security headers

Missing CSP, X-Frame-Options, nosniff and more, the easy wins that block XSS and clickjacking.

📂

Exposed files

Publicly reachable .env, .git, backups, and config files leaking your secrets.

🔑

Hardcoded secrets

API keys, tokens and passwords sitting in your code, and in your git history.

📦

Vulnerable dependencies

Known CVEs in your npm / pip / composer packages, mapped to severity.

💉

Risky code patterns

SQL injection, XSS, weak cookies, wide-open CORS, and debug mode left on in production.

🚪

Open admin & access control

Unprotected admin panels, default credentials, and publicly exposed cloud storage.
