Top Priorities (5)

Sorted by impact

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers

HSTS header is missing

Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

Security › Security Headers

No favicon or icon links detected

Without a favicon, your tab shows a blank icon and bookmarks look unbranded — amateur signal in every browser surface.

Accessibility › Favicon & Branding

16 inline style attribute(s) detected

Inline style attributes force `style-src 'unsafe-inline'` in any CSP -- effectively negating CSP's XSS-mitigation value for stylesheets.

Security › CSP Inline-Style Readiness

Cross-Origin-Embedder-Policy header is missing

COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.

Security › Security Headers

What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Addressing the critical issues below would have the most immediate impact on your user trust.

4 security gaps detected — browsers may warn visitors about your site.

1 accessibility issue excludes users who rely on assistive technology.

Content

Nav

Page takes 7.3s to load
Users abandon at ~3s — you're 4.8s over the 2.5s threshold
→ Optimize render-blocking resources, preload the hero image, and compress images
Severe layout shift during page load
Users mis-click when content jumps — converting intent into frustration
→ Reserve space for images, ads, and embeds with explicit width/height
No HSTS header
Returning visitors are briefly exposed to downgrade attacks on first request
→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
No Content-Security-Policy header
Higher XSS blast radius — one compromised script can exfiltrate the checkout form
→ Ship a reporting-only CSP first, then enforce once violations are clean
No Open Graph tags
Links shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop
→ Add og:title, og:description, og:image, og:url to the page head

Observations (2)

No build tool detected

A framework (Ubuntu) was detected but no bundler was identified. The build tool may not be detectable from output patterns, or the site may use the framework's built-in bundler.

Minimal technology footprint

Only 2 technologies detected. This suggests a simple setup with minimal dependencies — excellent for performance and security.
