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 'LocChecked' 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.
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.
Page weighs 17.8 MB (6.3 MB transferred)
Informational: total page weight (uncompressed) and bytes actually transferred over the wire.

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
8 barrier(s) likely increasing bounce by ~29%.
- Page takes 4.3s to loadUsers abandon at ~3s — you're 1.8s over the 2.5s threshold→ Optimize render-blocking resources, preload the hero image, and compress images
- Page feels frozen for 17.9sClicks 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
- 1 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
