About CertAvert and CertNotify

In their own words, as submitted to SaaSHub.

CertAvert
CertNotify

Features and specs

What each product offers, as listed by its team.

CertAvert 8 features
CertNotify 5 features
  • Expiry alerts
    Emails before a certificate expires; alert days scale to short-lived certificates
  • Problem detection
    Finds expired, revoked and untrusted certificates, broken chains, hostname mismatches and old TLS versions
  • Certificate change alerts │
    Tells you when a certificate is replaced, and whether it looks routine or unexpected
  • Every address checked
    Checks the certificate on every IP a domain resolves to, on any port
  • Slack and Discord alerts
    Alerts in Slack or Discord channels on paid plans, plus several email addresses
  • Free tools
    SSL/TLS, SANs, chain, TLS and DNS checks, no account needed
  • Certificate and CSR decoder
    Reads a pasted certificate, chain or CSR; a chain comes back in order
  • Audit reports
    Pro: a dated PDF/CSV report of every certificate, with report IDs anyone can verify
  • Focused purpose
    CertNotify is built around monitoring SSL/TLS certificate expiration and sending alerts. A narrow focus like this usually means a simple setup, with no need to learn a large monitoring suite.
  • Prevents outages
    Advance expiry warnings help teams renew certificates before they lapse. This avoids browser security warnings, broken APIs and lost customer trust.
  • Low operational overhead
    As a hosted service, it needs no self-hosted infrastructure or scripts to maintain. You add your domains or endpoints and receive notifications.
  • Useful for multiple domains
    Centralized tracking suits teams or agencies that manage many certificates across domains, subdomains and clients. Everything is visible in one place instead of in scattered calendar reminders.
  • Alerts to the right people
    Notification-based workflows let you reach the relevant people, such as sysadmins, DevOps or account owners, before a certificate expires. This reduces the risk of one person's forgotten renewal.
