SSL, Domain & DNS Monitoring·certly.dev

Certly monitors SSL certificates, domain expiry, and DNS/DNSSEC records across a user's sites, checking what the server actually serves rather than just registry paperwork. It sends staged alerts (30, 14, 7, and 1 day before expiry) via Slack, Discord, email, or webhook, and tracks a timeline of DNS record changes to flag dangerous ones. It also checks domain suspension status and email spoofing exposure (DMARC/SPF).
