Frequently Asked Questions
What does the website security checker scan for?
We run 50+ automated checks covering SSL/TLS configuration, HTTP security headers (CSP, HSTS, CORS, X-Frame-Options), DNS and email authentication (SPF, DKIM, DMARC), content vulnerabilities (outdated JS libraries, exposed files), and cookie security.
Is the security check free?
Yes. The free tier runs all 58 security checks for free. Upgrade to the paid plan to unlock unlimited scans on multiple domains and continuous monitoring with alerts.
How often should I check my website security?
We recommend running a security check after every deployment, when you change hosting or DNS settings, and at least monthly. Security configurations can drift over time as dependencies update and infrastructure changes.
Is this scanner safe to use on my website?
Absolutely. Our scanner is completely non-intrusive — it only makes standard HTTP requests that any browser would make. We never attempt to exploit vulnerabilities or perform penetration testing.
