HTTPS Security Checker

We'll check HTTPS, redirects, security headers and mixed content.

 

What Each Check Means

HTTPS

Checks whether your site is using a secure connection.
Why it matters: It protects data between your site and your visitors. Modern browsers expect every site to use HTTPS.

HTTP → HTTPS Redirect

Checks if visitors are automatically sent to the secure version of your site.
Why it matters: Without this, people can land on an insecure page without realising.

Mixed Content

Checks if a secure page loads any images, scripts or files over an insecure link.
Why it matters: Mixed content weakens security and can trigger browser warnings that put people off.

Strict-Transport-Security (HSTS)

Checks if your site tells browsers to always connect securely.
Why it matters: It stops anyone accidentally using the insecure version of your site.

Content-Security-Policy (CSP)

Checks whether your site controls where scripts and other files can load from.
Why it matters: CSP helps block attackers from injecting malicious code.

X-Content-Type-Options

Checks if the browser is prevented from guessing file types.
Why it matters: This avoids attacks where harmful files pretend to be something safe.

X-Frame-Options

Checks whether other websites are allowed to embed your site inside a frame.
Why it matters: Blocking framing prevents “clickjacking,” where users are tricked into clicking hidden buttons.

Referrer-Policy

Checks how much information your site shares when someone clicks a link to another site.
Why it matters: A good policy protects user privacy.

Permissions-Policy

Checks whether your site controls access to things like cameras, microphones or location data.
Why it matters: It limits your site to only the features it actually needs, improving safety.
