2
Increase HSTS max-age duration
HSTS is enabled but the max-age (0s) is below the recommended minimum of 15768000s (6 months). A short max-age means browsers forget the HTTPS-only policy quickly, reducing protection between visits.
Compliance impact
PCI-DSS 4.0Req 6.4.1
Application security header configuration
How to fix this
1
Update header: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
2
Verify: curl -sI https://crunchbase.com | grep -i strict
3
Add optional security headers (CSP, Permissions-Policy)
crunchbase.com has most security headers configured. Missing: CSP, Permissions-Policy. These are best-practice additions that reduce the attack surface for client-side vulnerabilities.
How to fix this
1
Add Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: Permissions-Policy: camera=(), microphone=(), geolocation=()
3
Verify with: curl -sI https://crunchbase.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
