Free security check
Enter your website address. In a minute you see how your site and e-mail domain look to an attacker.
What the check does
- Opens your page once, like an ordinary visitor, and reads the security headers.
- Checks HTTPS, the certificate and TLS versions.
- Looks up e-mail protection (SPF, DKIM, DMARC) in public DNS records.
What the check doesn't do
- It doesn't scan ports or probe for vulnerabilities.
- It doesn't store your IP address. We keep only the domain and the result.
- It's no substitute for a pentest: it's a first overview.
