What does the website scanner check?
A complete website scan is more than one test. The scanner runs every check below against your domain at once and combines them into a single security check with a grade from A to F. Need only one aspect? Each area also has its own dedicated tool.
TLS certificate, validity, cipher.
SPF, DMARC, DKIM and MX records.
HSTS, CSP, X-Frame-Options & co.
A, AAAA, MX, NS, TXT, CAA, SOA.
Registrar, expiry, status, name servers.
20 common TCP ports, critical ones flagged.
Set-Cookie headers, flags, tracker detection.
Want everything in one report? The full Webscan Radar security scan combines all areas plus GDPR audit, CMS detection and CVE matching — also free, no account. Or browse all single-check tools.
Website scanner — frequently asked questions
What does the website scanner check?
The website scan covers your SSL/TLS certificate, HTTP security headers (HSTS, CSP, X-Frame-Options and more), DMARC/SPF/DKIM email protection, DNS records, open ports, cookies and known CVEs in detected software — a full security check in one pass.
Is the website scanner free?
Yes. You can scan any domain for free without an account. A free email registration only unlocks the full PDF report and your scan history.
Is it a website scanner or a domain scanner?
Both. You enter a domain (e.g. example.com) and the scanner checks the website and the domain's DNS, mail and certificate setup in a single website scan.
How long does a website scan take?
Usually 10 to 20 seconds. Complex domains with many subdomains or slow DNS servers can take up to a minute.
