Top Priorities (5)

Sorted by impact
Critical: 1

Content-Security-Policy header is missing

Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.

Security › Security Headers
Critical: 2

HSTS header is missing

Without HSTS, a network attacker can downgrade the very first connection to HTTP and steal the user's session.

Security › Security Headers
Critical: 3

No Content-Security-Policy header found

Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.

Security › Content Security Policy
Warning: 4

65 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.

Performance › Page Weight Inventory
Warning: 5

Cross-Origin-Embedder-Policy header is missing

COEP enforces that all embedded resources opt-in to cross-origin embedding — required for cross-origin isolation features.

Security › Security Headers
What fixing these means. Your site performs reasonably well, but a few targeted fixes could meaningfully improve results. Your LCP of 13.2s exceeds Google's 2.5s 'Good' threshold and the 1 performance issue below directly contributes to it. Addressing the critical issues below would have the most immediate impact on your user trust.
4 security gaps detected — browsers may warn visitors about your site.
Your LCP is 13.2s — fixing the 1 performance critical could bring it under Google's 2.5s 'Good' threshold.

  • Page takes 13.2s to load

    → Optimize render-blocking resources, preload the hero image, and compress images
  • 19 broken link(s) on the page
    Clicks land on 404s — trust drops and the session often ends
    → Fix or remove the broken destinations surfaced on the Content tab
  • No HSTS header
    Returning visitors are briefly exposed to downgrade attacks on first request
    → Set Strict-Transport-Security: max-age=31536000; includeSubDomains
  • No Content-Security-Policy header
    Higher XSS blast radius — one compromised script can exfiltrate the checkout form
    → Ship a reporting-only CSP first, then enforce once violations are clean

Observations (3)

No build tool detected

A framework (Apple) 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Bootstrap version may be outdated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 3.3.1. The current major version is 5. Consider updating for security patches and new features.

Complex technology stack detected

18 technologies identified. A complex stack increases maintenance burden and attack surface. Consider whether all components are actively needed.
