Wissen Sie es, bevor Ihre Kunden es wissen.
A deployment overwrites a security header. A DNS migration drops a record. A cookie banner regresses to set tracking before consent. Monitoring catches it — and alerts you on change, not at month-end.
10 monitors under full coverage. Uptime every minute, weekly browser-side deep scans with drift alerts on cookie / a11y / pre-consent / perf changes. EU-hosted in Germany.

Wie oft wir prüfen
Unterschiedliche Dinge ändern sich unterschiedlich schnell.
Uptime can fail in seconds. Cookies regress with each release. A certificate renews every 60-90 days. Each check runs at the right cadence — caught fast where it matters, efficient where it doesn't.
Uptime & Antwortzeit
HTTP/HTTPS-Erreichbarkeit, Statuscode, Antwortzeit, Keyword-Abgleich
Sicherheitslage-Note
Headers (HSTS, CSP, X-Frame), DNSSEC, CAA, A-F grade with degradation alerts
SSL-Zertifikat
Ablauf, Aussteller, TLS-Version, Forward Secrecy, OCSP
E-Mail-Authentifizierung
SPF-, DKIM-, DMARC-Einträge, Blacklist-Prüfungen
DNS-Konsistenz
Erkennung von Eintragsabweichungen, Hijack-Schutz, Resolver-Abgleich
Cookie + accessibility deep scan
Real-browser audit, drift alerts on regression
Domain-Registrierung
WHOIS, Ablaufdatum, Registrar, Nameserver-Änderungen
Jeder Sicherheitsalarm wird vor dem Versand durch eine zweite Prüfung bestätigt — keine Fehlalarme durch kurzzeitige Störungen.
What's included in Pro
The full continuous-monitoring toolkit for production sites — uptime, security, drift detection, CSP, multi-channel alerts.
10 Monitore
Cover up to 10 websites or services with full security + uptime coverage on each.
1-minute uptime
HTTP/HTTPS checks every minute. Response time tracking, status codes, confirm-on-change before paging.
Drift-Alerts
Cookie banner regresses? CSP weakens? Pre-consent tracker appears? You're alerted within hours of the change, not at the next audit.
Pre-consent drift = critical
A site that suddenly sets analytics cookies before consent is a GDPR / ePrivacy violation. We flag it as critical, not just informational.
Performance regression
Core Web Vitals tracked weekly. LCP, INP, CLS regressions alert before they hit your SEO ranking.
CSP-Reports — 100k/Tag
HMAC-signed ingest URL, aggregated dashboard, recommendation engine. Catch rogue scripts before users do.
TCF + CMP drift monitoring
Validate the IAB TCF string emitted by your CMP. Detect when a CMP misconfiguration breaks downstream consent signalling.
All alert channels
Email, Slack, Microsoft Teams, Discord, Telegram, generic webhook. Severity routing rules included.
Status page
Public status page with subscribed updates. "Powered by SiteGuardian" stripe — full white-label is on Compliance.
API read + MCP server
REST API key for read access, plus the MCP server tool surface for AI clients (Claude, Cursor, etc.).
Subdomain-Erkennung
Automatic discovery of subdomains for one-click monitor creation.
90 Tage Verlauf
Three months of trend data — long enough to catch quarterly regressions.
