Monitoring Modules

NOB.center is organized into monitoring modules. Each module covers a specific layer of your domain's trust plane and operates independently — you can use any combination depending on your needs.

Available modules

CT Log Certificate Transparency Monitoring
Watch every certificate issued for your domains across all public CT logs. Configure domain filter patterns, view matching certificates, and get alerted on unauthorized issuances or suspicious activity.
DNS DNS Monitoring
Track changes to your DNS records. Add domains, select which record types to watch, and receive alerts when changes are detected. Includes a history viewer and snapshot diff tool.
RDAP RDAP / WHOIS Monitoring
Monitor domain registration data from RDAP registries. Detect changes to registrar, nameservers, expiry dates, and domain status. Includes a snapshot viewer and diff tool.
Cert Certificate Deployment Monitoring
Actively scan your servers to verify the certificates they present. Monitor expiry, TLS protocol support, cipher suite strength, and chain validity across multiple IP targets.
Reports Reports
Weekly audit snapshots combining findings from all modules into a scored report (A–F). Downloadable as PDF and deliverable by email.

Shared capabilities

Every module shares the same alerting infrastructure:

  • Alert rules — CEL-based conditions that evaluate against each incoming event
  • Alert templates — delivery configuration (email or webhook, immediate or batch)
  • Alert history — a log of every dispatched alert with status and event data

See Alerting Model for a complete reference.

Each module also respects the same Roles & Permissions model — users get Viewer or Editor access per module independently.
