Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
1 button(s) with no accessible text
Buttons with no accessible text (icon-only, no aria-label) can't be activated by voice control or understood by screen readers.
6 image-in-link without alt text
Image-only links with no alt create empty links — screen-reader users hear 'link' with no destination context.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment

Figures combine localized regulatory fine ceilings, search/conversion value priced against local CPC, and bandwidth waste estimates. Results depend on implementation quality and audience composition. Not legal or financial advice.
Conversion barriers
12 barrier(s) likely increasing bounce by ~37%.
- Page takes 9.7s to loadUsers abandon at ~3s — you're 7.2s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 1.7sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- Severe layout shift during page loadUsers mis-click when content jumps — converting intent into frustration→ Reserve space for images, ads, and embeds with explicit width/height
- 44 broken link(s) on the pageClicks land on 404s — trust drops and the session often ends→ Fix or remove the broken destinations surfaced on the Content tab
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains

Observations (7)
Server version exposed in headers
The Server header reveals 'OpenResty 1.21.4.1'. Exposing exact server versions helps attackers target known vulnerabilities. Consider configuring your server to hide version information.
jQuery loaded alongside a modern framework
Both jQuery and Vue.js are loaded. Modern frameworks handle DOM manipulation natively. jQuery may be unnecessary and adds ~30KB to the page weight. Check the Performance tab for bundle analysis.
No build tool detected
A framework (Babel) 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.
Bootstrap version may be outdated
Detected Bootstrap 3.3.6. The current major version is 5. Consider updating for security patches and new features.
Vue.js version may be outdated
Detected Vue.js 2.4.2. The current major version is 3. Consider updating for security patches and new features.
jQuery version may be outdated
Detected jQuery 2.2.2. The current major version is 3. Consider updating for security patches and new features.
Complex technology stack detected
17 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
