Top Priorities (5)
HSTS header is missing
Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.
241 HTTP requests — consider bundling or reducing
High HTTP request count — bundling, sprite-ing, and HTTP/2 server push can reduce per-request overhead.
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.
Cross-Origin-Opener-Policy header is missing
COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.
External script from analytics.tiktok.com lacks integrity attribute
External resource without SRI — if the third-party CDN is compromised, your site executes attacker-controlled code.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
€510 investment → €6,003/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
7 barrier(s) likely increasing bounce by ~27%.
- Page takes 20.7s to loadUsers abandon at ~3s — you're 18.2s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 1.4sClicks on the primary CTA are ignored while JavaScript runs→ Break up long tasks; defer non-critical JavaScript to post-hydration
- 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
- Content is hard to readGraduate-level reading difficulty — limits the addressable audience for product or blog pages→ Shorten sentences; replace jargon with plain language; target Flesch ease ≥60

Compliance figures represent the statutory maximum fine for the most severe triggered category, capped per regulation — not the sum of per-finding penalties. Based on published regulatory fine ranges. This is not legal advice.

Observations (2)
No build tool detected
A framework (FingerprintJS) 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
23 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
