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.
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.
//:0 is missing width/height — may cause layout shift
Image without explicit width/height — browser can't reserve space; CLS jumps when image loads.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
PLN 975 investment → PLN 44,968/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 ~25%.
- Page takes 7.2s to loadUsers abandon at ~3s — you're 4.7s 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 280ms 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
- 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

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Bootstrap version may be outdated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 3.3.7. The current major version is 5. Consider updating for security patches and new features.
Complex technology stack detected
11 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
