DomainCat information
What is DomainCat?
DomainCat is a clean, purpose-built SSL and domain monitoring platform for infrastructure professionals and MSPs who manage certificates on behalf of clients. Unlike generic uptime tools that bolt on SSL checks as an afterthought, DomainCat is built around the MSP workflow — track certs you own, certs you host for others, and alert the actual cert owner when action is needed. Key features:
SSL certificate monitoring with escalating alerts at 30, 14, and 7 days Full domain health: WHOIS, DNS records, SPF, DKIM, DMARC, blacklist checks MSP mode — manage certs on behalf of clients with owner-direct alerting Grafana-compatible REST API No agents, no firewall holes — outbound port 443 only
