Free tool · Passive website security check

Is your business website safe for your customers?

Enter your website address. We visit your public pages like a careful visitor would and check them for security problems: missing protections, unsafe scripts, hidden iframes, risky redirects, certificate issues and links to known malicious sites.

Start a check

Full web-check graphs, DNSBL / geo tiles, and animated posture radar — no scan required.

What we check

Passive scan plus web-check-style analytics graphs — still read-only, no attacks.

Encryption

HTTPS, certificate validity and expiry, TLS version, and whether HTTP redirects to HTTPS.

Security headers

HSTS, Content-Security-Policy, clickjacking protection, nosniff, Referrer- and Permissions-Policy, cookie flags.

Scripts & content

Obfuscated or encoded JavaScript, crypto miners, card-skimmer patterns, hidden iframes, mixed content, missing Subresource Integrity.

Reputation & files

Redirect chains, other domains your pages use, open threat-intelligence lists, and hashes of linked files scanned for malware.

Web-check analytics

DNS, DNSSEC, TXT/CAA/MX, WHOIS age, carbon estimate, trackers, CDN hints, archives and more with animated gauges. Port scan, traceroute and Shodan stay off by policy.

Questions

Will this harm or slow down my website?

No. We fetch at most 15 public pages, one at a time with a pause between requests, and stop at any path your robots.txt disallows. It is the same traffic as one visitor clicking through your site.

Is this a penetration test?

No. A penetration test actively tries to break in. This check is passive: it reads what your site already shows to everyone and flags known warning signs. For a full test, hire a qualified security firm.

Can I check someone else's website?

Only with their permission. You must confirm you own the site or are allowed to check it before a scan starts.

Do you store my results?

Interactive tool results are kept in memory for about an hour so you can view them, then deleted. Download the JSON report if you want to keep it. Separately, the Wordle crawler publishes automatic OSINT security checks for software websites — those saved reports appear in the registry above (review page + security-report anchor) and at /your-domain/.

A finding seems wrong. What now?

Automated checks look for patterns, so some findings need a human look. Use the evidence shown with each issue to confirm it with your web developer.
