SiteGuardian monitors websites, scores their security posture, and documents everything for the auditor. SSL certificates expire at 3 AM. Domains lapse because the renewal email hit spam. SPF breaks during a DNS migration and invoices land in junk for two weeks. Most teams find out from their customers — not their tooling. SiteGuardian watches uptime, SSL, domains, DNS, email health (SPF/DKIM/DMARC), security headers, and response times around the clock. Every site gets a continuously updated A-to-F security posture score. Checks run as fast as every 30 seconds. The compliance engine maps monitoring data against 17+ EU regulatory frameworks — GDPR, NIS2, CRA, EAA, DORA, and their national implementations. Every check, every alert, every incident is logged and timestamped in a tamper-evident evidence vault. When the auditor asks for proof of continuous monitoring, you hand them a PDF — not a spreadsheet you assembled overnight. Supply chain monitoring for NIS2 Art. 21. Accessibility scanning for the European Accessibility Act. SLA reporting. Cookie compliance. DPA/AVV digital signing built in.
