Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
No <main> landmark found
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
45 third-party resources (100% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
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.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
$717 investment → $13,092/month returns + USD 157,500 risk avoided
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
8 barrier(s) likely increasing bounce by ~28%.
- Page takes 9.5s to loadUsers abandon at ~3s — you're 7.0s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- High main-thread blocking timePage is non-interactive for 468ms after first paint→ Defer third-party scripts and split large bundles
- No HSTS headerReturning visitors are briefly exposed to downgrade attacks on first request→ Set Strict-Transport-Security: max-age=31536000; includeSubDomains
- No Content-Security-Policy headerHigher XSS blast radius — one compromised script can exfiltrate the checkout form→ Ship a reporting-only CSP first, then enforce once violations are clean
- Viewport disables user zoomVisitors with low vision can't read the page — and some jurisdictions treat this as a legal risk→ Remove user-scalable=no; drop maximum-scale if it's below 2

Observations (3)
No build tool detected
A framework (Backbone.js) 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.
jQuery version may be outdated
Detected jQuery 2.2.3. The current major version is 3. Consider updating for security patches and new features.
Complex technology stack detected
19 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
