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.
91 third-party resources (100% of weight)
Informational: third-party resource count and their share of page weight. High share caps perf gains from frontend optimization.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.

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 17.4s to loadUsers abandon at ~3s — you're 14.9s 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
- 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
- 145 link(s) with generic text ("click here", "read more")Screen-reader users navigating by link list see no context — and search engines can't infer relevance→ Rewrite with descriptive phrases that identify the destination

Observations (4)
Server version exposed in headers
The Server header reveals 'Apache 2.4.65'. Exposing exact server versions helps attackers target known vulnerabilities. Consider configuring your server to hide version information.
Runtime exposed via X-Powered-By header
The X-Powered-By header reveals 'PHP 8.4.15'. Remove this header in production to reduce information leakage.
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
13 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
