Xitoring's SSL monitoring is deep. The choice is really about focus and how you pay.
Verified 19 Aug 2026
Xitoring's SSL monitoring is genuinely deep, and this page will not pretend otherwise. Its own SSL page documents expiry warnings at 30, 14, 7, and 1 day, full chain validation from root to leaf, Certificate Transparency tracking, wildcard and SAN coverage, OCSP and CRL revocation checks, and A+-to-F TLS grading. If you want that depth folded into one platform that also does server and uptime monitoring, Xitoring is a strong choice, and this page is not going to pretend otherwise.
CertPost is the opposite bet: it competes on focus and flat pricing.
Xitoring's SSL monitoring is one pillar of a broader server-and-uptime platform. CertPost does certificates and the things immediately around them — nothing else — so the product, the dashboard, and the alerts are built for the one job. It adds the layer a general platform's SSL check tends not to: domain-registration expiry (the name lapses, not the certificate), DNS record drift, and the mail and admin ports — SMTP 465/587, IMAPS 993, panels on 8443 — checked on the wire from outside, so a renewal that succeeded on disk but never reloaded is caught. There is also a free agent-readiness check for how your site presents to AI crawlers.
On pricing, Xitoring is priced per monitor — your plan buys a monitor count, and SSL checks draw from it, so cost rises with the number of certificates. CertPost is flat: three certificates free forever, then $29/month for unlimited certificates. If you watch a lot of certificates, a flat price is the whole argument.
If SSL is one part of a wider monitoring platform you already want, Xitoring covers it well. If certificates are the job, a focused tool at a flat price — with the domain, DNS, and mail ports around them — is less to run and cheaper to scale.
Trying CertPost alongside Xitoring:
1. Paste your certificates into CertPost free — no card, three watched forever.
2. Add the hostnames Xitoring's SSL page does not cover by default: mail and admin ports, and the apex domain for registration expiry.
3. Compare the two dashboards on the certificates you care about most, then decide per-certificate where each belongs.
Import your domain list in 2 minutes — 3 certificates free, no card.
