SSL Certificate Monitors
Avoid surprise HTTPS outages.
Track SSL/TLS certificate expiry and get alerts before certificates expire.
SSL monitoring
SSL monitors connect to your host on port 443 (or a custom port) and read certificate metadata. SurePing alerts when expiry falls within your warning window.
Expired certificates cause browser errors and API failures even when your app process is running fine.
Best practice
Add an SSL monitor for every production hostname. Set alerts at 30 and 14 days before expiry. Automate renewal with Let's Encrypt or your CA, and keep the monitor to catch failed renewals.
