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.
1 image-only link(s) without alt text
Image-only links with no alt are unidentifiable to screen-reader users — link's destination is invisible.
21 third-party resources (73% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Certificate expires soon (29 days remaining)
Cert expiry within the renewal window — fix now while there's no user impact, instead of after expiry when there's a full outage.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€560 investment → €742/month returns + EUR 120,500,000 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
6 barrier(s) likely increasing bounce by ~16%.
- 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
- Layout shifts during page loadContent movement causes mis-clicks on CTAs and form fields→ Add width/height to images; reserve space for late-loading embeds
- No Open Graph tagsLinks shared on LinkedIn / Slack / Facebook show bare URLs — referral clicks drop→ Add og:title, og:description, og:image, og:url to the page head
- No structured dataNo rich-result eligibility in Google — lower SERP CTR vs competitors with stars and prices→ Add JSON-LD for your page type (Product, Article, FAQPage, LocalBusiness, …)

Observations (2)
No build tool detected
A framework (Google Search Console) 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.
Complex technology stack detected
11 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
