Monthly Website Health Report
Prepared for DutchBike Rentals · generated 1 June 2026
Executive summary
DutchBike's site stayed online with strong uptime. The main risk is email security: no DMARC record was found, leaving the domain open to spoofing.
Security & reliability health
| SSL / TLS | Valid · 167 days |
| DNS | Stable |
| Email security (SPF/DMARC) | SPF present · DMARC MISSING |
| Security headers | B (78%) |
Recommendations
- Add a DMARC record (start with p=none, then enforce).
- Add a Content-Security-Policy header.
Technical appendix
Checks are passive and read-only (HTTP/HTTPS uptime, SSL certificate, DNS records,
SPF/DMARC, HTTP security headers) on the schedule configured for DutchBike Rentals. Uptime is measured from
external probes; the risk score is a weighted blend of all signals (0–100).
