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.
2 software version(s) disclosed in HTML: Elementor 4.2.4; features: e_font_icon_svg, additional_custom_breakpoints; settings: css_print_method-external, google_font-enabled, font_display-auto, WordPress 7.1
Each disclosed version enables direct CVE lookup -- attacker reads the version, searches the CVE database, targets the site with a tested exploit.
20 render-blocking <script src> tag(s) without async/defer
Performance issues directly impact user engagement and conversion rates.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment

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 ~24%.
- Page takes 5.9s to loadUsers abandon at ~3s — you're 3.4s 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
- 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 (3)
WordPress detected — review security configuration
WordPress sites benefit from: protecting wp-login.php, disabling XML-RPC if unused, restricting REST API access, and keeping all plugins and themes up to date. Check the Security tab for specific findings.
No build tool detected
A framework (Animate.css) 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
20 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
