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.
Page weighs 17.6 MB (16.5 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
38 link(s) with no accessible text
Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
CHF 878 investment → CHF 9,278/month returns + CHF 250,000 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 ~29%.
- Page takes 85.0s to loadUsers abandon at ~3s — you're 82.5s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- 53 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
- High main-thread blocking timePage is non-interactive for 400ms 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
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

Observations (3)
No build tool detected
A framework (Bootstrap) 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Bootstrap version may be outdated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 3.4.1. The current major version is 5. Consider updating for security patches and new features.
Complex technology stack detected
14 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
