PingWise
SSL & domain expiry

Never let a certificate expire again.

PingWise watches your TLS/SSL certificates and your domain registration and warns you days in advance before either expires — so a lapsed certificate never throws browser security warnings and an expired domain never takes your site offline.

Certificate & domain expiry, handled

SSL expiry warnings

PingWise reads your certificate and alerts you a configurable number of days before it expires — with plenty of time to renew.

Domain expiry monitoring

Looks up your domain registration (via RDAP/WHOIS) and warns you before the domain lapses — the outage nobody sees coming.

Certificate validity checks

Confirms the certificate is present, valid and correctly served on every check, not just that the site loads.

Choose your warning window

Set how many days in advance you want to be warned — per certificate and per domain.

Alerts everywhere

Expiry warnings by email, SMS, Slack, Microsoft Teams, Discord, Telegram, webhook and ClickUp.

Add-on to uptime

Tick “also watch the SSL certificate” on any website monitor, or add a dedicated SSL / domain monitor — your choice.

SSL monitoring FAQ

What is SSL certificate monitoring?

SSL (TLS) certificate monitoring checks that your certificate is valid and correctly served, and warns you before it expires. An expired certificate makes browsers show a security warning and blocks visitors, so early notice is essential.

How far in advance will I be warned?

You choose. Set the warning window in days per certificate (and per domain), so you get alerted with enough time to renew comfortably.

Can PingWise also monitor domain expiry?

Yes. As well as the TLS certificate, PingWise can watch your domain registration and warn you before the domain itself lapses — a common and painful cause of downtime.

Is there a free plan?

Yes. Start free with no credit card. You can watch a certificate on the free plan, and paid plans add more monitors, faster checks and extra alert channels.
