SSL certificate monitoring & expiry alerts

Track TLS certificate expiration and get reminders at 30, 14, and 7 days before the deadline — so renewals happen before browsers show warnings.

Why expired SSL is risky

Browsers block or warn users when certificates lapse. That means lost conversions, broken trust, and support noise. Monitoring expiry dates turns renewal into a scheduled task instead of an emergency.

What SSL monitoring checks

SitePuls inspects the certificate served by your hostname and counts down to expiration. You see upcoming renewals alongside your other monitors instead of relying on calendar reminders alone.

Alerts that reach the right owner

Send notifications by email or Telegram so whoever owns DNS or hosting can renew or reissue in time. Combine with website monitors to correlate cert issues with user-facing errors.

Who needs certificate monitoring

Anyone shipping HTTPS — marketing sites, SaaS apps, APIs, and client projects where multiple people touch infrastructure. Especially teams juggling dozens of hostnames across registrars and CDNs.

How alerts help avoid outages

Lead time beats firefighting. When reminders arrive early, you can renew through your CA or hosting flow without rushing a broken deploy Friday night.

Pair with domain monitoring

Certificates and domain renewals are different clocks. Track both so neither surprises you — domain lapses can break DNS before SSL even matters.

Related checks

Add website or API monitors for the same host to catch mis-issued certs or broken chains when responses still return 200 but clients see errors.

Quick setup

Add the hostname, confirm alert contacts, and let SitePuls track the not-after date. No agent installation — checks run from our infrastructure like your other monitors.

Frequently asked questions

What is SSL certificate monitoring?

SSL certificate monitoring checks your domain's HTTPS certificate and warns you before it expires. You get alerts at 30, 14, and 7 days before expiration so you have time to renew and avoid security errors for users.

When should I renew my SSL certificate?

Renew before the expiry date. SitePuls sends reminders at 30, 14, and 7 days so the right person can renew in time. Many certificate providers allow renewal while the current certificate is still valid.

What happens if my SSL certificate expires?

Browsers will show security warnings and some users may not be able to access your site. Monitoring helps you avoid this by alerting you in advance. Combine it with website and uptime monitoring for full visibility.

Does monitoring replace my certificate authority’s reminders?

CA emails help, but they’re easy to miss. SitePuls keeps expiry visible next to uptime incidents so operational teams see it in the same workflow as other alerts.

Can I monitor wildcard certificates?

Add monitors for each hostname you need to watch. SitePuls evaluates the certificate presented on those connections — match hostnames to how users reach your services.

Will I get alerted about short-lived certs?

Yes — the countdown is based on the actual not-after date, whether the cert is annual or rotated more frequently.

What channels support SSL alerts?

Email and Telegram for SSL-specific reminders, consistent with other monitor types.

Should I also monitor the domain?

Yes. Domain expiry can take a site offline even when SSL is valid. Use domain expiry monitoring alongside SSL checks for complete coverage.
