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.
3 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
125 HTTP requests — consider bundling or reducing
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
CHF 1,398 investment → CHF 13,139/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
4 barrier(s) likely increasing bounce by ~20%.
- Page takes 7.6s to loadUsers abandon at ~3s — you're 5.1s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- 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
- No skip-to-content linkKeyboard and screen-reader users must tab through the entire header on every page→ Add a visible-on-focus <a href="#main">Skip to content</a> as the first focusable element
Preliminary CRO audit — each barrier links to the tab with detailed analysis.
