Frequently asked questions
▸How do I scan my website for vulnerabilities for free?
Enter your site address in the bar above and run the audit. In seconds, CheckCyber checks 24 security points (SSL certificate, HTTP headers, DNS, exposed files, mixed content, script integrity…) and returns a score out of 100 with every finding and its fix. It is free, anonymous and requires no signup.
▸What kinds of security flaws does CheckCyber detect?
It detects expired or weak SSL/TLS certificates, obsolete protocols (TLS 1.0/1.1), missing security headers (HSTS, CSP, X-Frame-Options), exposed sensitive files (.env, .git, backups), dangerous HTTP methods, email protection gaps (SPF, DMARC, CAA) and JavaScript libraries running a known-vulnerable version.
▸Do I need technical skills to use CheckCyber?
No. You only enter a site address. The report translates every problem into plain language and gives you the exact fix for each finding, with ready-to-paste configuration examples for Apache/.htaccess and nginx. Nothing to install.
▸Does CheckCyber work on WordPress, Shopify or a custom site?
Yes. The audit relies on the public server configuration (TLS, headers, DNS), independently of the underlying technology. It works on any publicly reachable site: WordPress, Shopify, Wix, PrestaShop or a fully custom build.
