Check any website for missing security headers, HTTPS/HSTS issues, clickjacking protection, and other common hardening gaps — with clear, prioritized fixes.
What this check analyzes
HTTPS & HSTS
Valid encryption and strict-transport-security enforcement.
Security headers
Content-Security-Policy, X-Frame-Options, Referrer-Policy, and more.
Clickjacking & MIME
Protections against framing and content-type sniffing attacks.
Prioritized hardening
Which header to add first and exactly how.
Every check runs a complete Webmatik audit — so alongside security, you also get performance, SEO, GEO, conversion, UX, accessibility, and security, all in one Growth Score.
Frequently asked questions
Is the security checker free?
Yes — run free security checks every month, no credit card required.
What does it check?
HTTPS and HSTS, key security headers (CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy), clickjacking and MIME-sniffing protections, and mixed-content issues.
Is this a full penetration test?
No — it audits the safe, behind-the-scenes hardening signals visible from the front end. It is a fast, useful health check, not a substitute for a full security audit.
