SSL Certificate Monitor
Track every certificate.
Never get caught expired.
Stop discovering expired certificates after the fact. Cert monitors every domain you care about, checks DNS health, and alerts you before expiry — so you stay ahead of outages and security warnings.
TLS certificate tracking
Live checks for every domain — issuer, expiry date, days remaining, protocol version, and cipher suite. Detects renewals automatically.
DNS health audits
Checks SPF, DKIM, DMARC, DNSSEC, MX records, and DNS propagation. Scores each domain and surfaces critical issues.
Subdomain scanner
Discovers certificates on common subdomains (www, vpn, remote, rdgw…) so nothing falls through the cracks.
Expiry alerts
Email and Microsoft Teams notifications at configurable thresholds. Set per-domain alert schedules or use global defaults.
Customer organisation
Group certificates by customer with customer numbers. Generate per-customer reports with DNS summaries and renewal history.
CSV export & reports
Export all certificates to CSV at any time. Generate branded HTML reports per customer — ready to send directly to clients.
