Top Priorities (5)
Content-Security-Policy header is missing
Without a CSP, a single XSS bug can exfiltrate everything your users type — including credentials.
No Content-Security-Policy header found
Without a CSP, a single XSS bug can exfiltrate everything users type — credentials, payment data, session tokens.
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.
Cross-Origin-Opener-Policy header is missing
COOP isolates your top-level browsing context from cross-origin windows — without it, popup-based side-channel attacks remain possible.
DMARC policy is none — monitoring only
DMARC p=none collects reports but doesn't actually block spoofed mail — phishing emails still reach inboxes.
Business case
What fixing the audit's findings is worth -- and what ignoring them keeps costing.
Return on investment
CHF 1,008 investment → CHF 6,614/month returns + CHF 250,000 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
2 barrier(s) likely increasing bounce by ~21%.
- No viewport meta tagMobile browsers render at desktop width and shrink — text unreadable, tap targets miniature→ Add <meta name="viewport" content="width=device-width, initial-scale=1">
- 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
Preliminary CRO audit — each barrier links to the tab with detailed analysis.

6How you compare
Where this site stands against peers running the same stack.
Top 10% of Amazon Route 53 sites score 68+ on Accessibility; you're at 28 — closing this gap is the highest-leverage improvement.
Top 10% of Google Workspace sites score 70+ on Accessibility; you're at 28 — closing this gap is the highest-leverage improvement.
Technology stack
Amazon Route 53, on Apache, hosted on Apache HTTP Server
Stack Architecture
All Detected Technologies (6)
Apache is a free and open-source cross-platform web server software.
HTTP Strict Transport Security (HSTS) informs browsers that the site should only be accessed using HTTPS.
OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end.
Observations (2)
Server version exposed in headers
The Server header reveals 'Apache 2.4.64'. Exposing exact server versions helps attackers target known vulnerabilities. Consider configuring your server to hide version information.
No build tool detected
A framework (Amazon Route 53) 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.
