Hardening your website security headers

HTTP security headers add defense-in-depth on top of TLS (SSL) to reduce risks like code injection, data leakage, and clickjacking.

How security headers protect your site

Always-HTTPS forces browsers to use HTTPS only, blocking insecure connections and downgrades
Allowlisted content only tells the browser where it’s allowed to load code, styles, images, and frames from, stopping most injection and XSS tricks
No clickjacking prevents your pages from being placed in someone else’s iframe to steal clicks or data
Less data leakage limits what referral information visitors’ browsers share with other sites
Powerful features off by default means camera, microphone, geolocation, and sensors are off unless explicitly needed
Origin isolation keeps your site’s browsing context separate and stops other sites reusing your resources without permission
No file-type spoofing blocks the browser from guessing MIME types, reducing drive-by download risks
Sane caching ensures public pages revalidate with the server, while logged-in, admin, REST, and AJAX responses aren’t cached

Reducing clues that assist targeted attacks

Strip fingerprints hides server and software versions and other about-this-server hints
Kill long-TTL HTML caching by removing long expiry headers on pages so they don’t get stuck in caches
Session hygiene when used, ensures cookies are secure, HTTP-only, and same-site to resist theft and CSRF

Does my site have hardened security headers?

You can check your site on securityheaders.com – a free scanner that grades your HTTP response headers and is a useful indicator of what’s missing or misconfigured (but it’s not a complete security review).

If your site doesn’t score an A+, contact Creative Passion®.

We’ll fine-tune your headers and security settings to reduce attack risks, limit data exposure and add protective guardrails — all while avoiding version leaks.

Ask us about regular maintenance to keep your site’s protections current, consistent and cared for.
