Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
Cookie 'PHPSESSID' is missing the Secure flag
A cookie without the Secure flag can leak over HTTP — in HSTS-protected sites, this is still a defense-in-depth gap.
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 13.8 MB (7.9 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.
18 image-in-link without alt text
Image-only links with no alt create empty links — screen-reader users hear 'link' with no destination context.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
CZK 7,425 investment → CZK 77,503/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
9 barrier(s) likely increasing bounce by ~31%.
- Page takes 47.1s to loadUsers abandon at ~3s — you're 44.6s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- 166 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
- 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
- 2 form field(s) without a labelScreen readers skip unlabeled fields; autofill can't identify them; checkout abandonment spikes→ Associate every input with a visible <label for="…">; add autocomplete attributes

Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.
PHP is a general-purpose scripting language used for web development.
HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.
Hammer.js is a JavaScript library for adding touch gestures like swipe, pinch, and rotate to web applications.
Open Graph is a protocol that is used to integrate any web page into the social graph.
Svelte is a free and open-source front end compiler created by Rich Harris and maintained by the Svelte core team members.
YouTube is a video sharing service where users can create their own profile, upload videos, watch, like and comment on other videos.
jQuery is a JavaScript library which is a free, open-source software designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax.
jQuery UI is a collection of GUI widgets, animated visual effects, and themes implemented with jQuery, Cascading Style Sheets, and HTML.
Matomo Analytics is a free and open-source web analytics application, that runs on a PHP/MySQL web-server.
Matomo Tag Manager manages tracking and marketing tags.
Observations (3)
jQuery loaded alongside a modern framework
Both jQuery and Svelte are loaded. Modern frameworks handle DOM manipulation natively. jQuery may be unnecessary and adds ~30KB to the page weight. Check the Performance tab for bundle analysis.
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.
Complex technology stack detected
15 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
