NOB.center Documentation

Platform Guide

NOB.center monitors the trust plane of your internet domains — the infrastructure that determines whether the internet considers your domains legitimate and your certificates trustworthy.

Four monitoring pillars work together to give you a complete picture:

CT Log Certificate Transparency Monitoring
Watch every certificate issued for your domains across all public CT logs. Catch unauthorized issuances, detect CA authorization violations, and track certificate issuance rates.
DNS DNS Monitoring
Track changes to the DNS records you care about — A, MX, NS, TXT, CAA, and more. Get alerted the moment something changes unexpectedly.
RDAP RDAP / WHOIS Monitoring
Monitor domain registration data for changes to registrar, nameservers, expiry dates, and domain status flags.
Cert Certificate Deployment Monitoring
Actively scan your servers to verify certificate validity, TLS protocol support, cipher suite strength, and chain completeness.

Weekly audit reports

All findings are rolled up into a weekly audit report with a letter grade (A–F) and a breakdown by category. Reports are available in the dashboard and can be delivered by email on a weekly schedule.

See Reports for details.

How alerting works

Every module supports custom alert rules written in CEL (Common Expression Language). Rules evaluate against incoming events and dispatch notifications by email or webhook — immediately or in batches. See Alerting Model to understand rules, templates, and destinations.
