Nexio Watch
SSL monitoring

Monitor SSL expiration for clients before browsers block traffic

Auto-renew fails, staging certs prod-pointed, and wildcard gaps take sites offline quietly. Get warned on every client hostname—not when a user sends a screenshot of NET::ERR_CERT_DATE_INVALID.

  • Dedicated SSL expiry monitor type per URL
  • Works alongside uptime and DNS on the same dashboard
  • Alerts to Slack, email, or SMS before expiry day

Takes ~60 seconds to set up

SSL expiry is the outage agencies forget until it’s urgent

Renewal emails go to the client’s IT alias you don’t see. A lapsed cert trashes trust faster than a slow page—and it’s always “your guy who manages the site.”

  • Let’s Encrypt failures on multi-domain hosts
  • Client moved DNS; cert still on old infrastructure
  • No calendar reminder tied to the actual certificate

Why calendar reminders and host panels fail

Manual spreadsheets don’t survive team churn; host SSL widgets don’t cover every hostname you manage.

  • One cert covers apex and www—monitors only watch one
  • SAN certificates expire on different dates than the “main” site
  • No alert routing to the agency Slack that actually responds
  • Uptime green while HTTPS is already broken for users

SSL monitoring inside your client uptime stack

Add certificate expiry monitors next to HTTP, DNS, and screenshot checks—one login for the whole agency roster.

  • Per-URL SSL monitors
    Track client apex, www, API subdomains, and staging—each with its own threshold and alert policy.
  • Bundled with uptime & DNS
    See cert, resolution, and availability issues together when triaging—not three separate tools.
  • Multi-region HTTP checks
    Confirm outages before paging—separate real downtime from a single-region blip.
  • Free tier for the long tail
    Ten monitors free covers smaller clients while paid plans handle minute-level checks for revenue sites.

Certificate warnings beside uptime timelines
