Pingdom (SolarWinds) monitors from 100+ locations, from $16.50 per month billed annually ($18 monthly) for 10 uptime checks. Review Visual Sentinel vs Pingdom for monitoring capabilities.
Datadog syncs data via webhooks. Review the supported integration settings for the tools you use.
API Configuration Basics
Review API authentication in the documentation for each tool. Visual Sentinel SSL reminders default to 13, 3, and 1 days before expiry (optional 20 and 6).
How Does SSL Expiration Monitoring Prevent Website Security Lapses?
SSL expiration monitoring reports approaching certificate expiry. Teams renew and install certificates, then verify secure access. Monitoring does not replace correct server configuration.
Pair SSL expiration monitoring with DNS Monitoring, which checks records on a schedule. Review certificate errors alongside the DNS records being served.
Tools like UptimeRobot flag approaching expiry. Teams still need to review renewal results.

How to Test SSL Expiration Monitoring Setup for Reliability?
Use staging certificates to test the expiry reminders supported by your monitoring tool. Website Checker provides a separate on-demand website availability check.
Simulation Techniques
Generate self-signed certificates valid for 7 days using OpenSSL in a staging environment. UptimeRobot's Solo plan costs $13 per month ($12 billed annually). Review how the tool handles untrusted certificates before relying on the expiry test.
Use Speed Test for correlated performance checks during simulations.
Validation Metrics
Measure alert delivery during test runs and investigate missed or delayed notifications. Keep the results for later review.
Run quarterly validations after setup and after changes to the delivery path.
DevOps engineers implement SSL expiration monitoring to review upcoming expiry dates. Start with a scheduled SSL monitor, for example UptimeRobot Solo at $13 per month ($12 billed annually). Configure SSL Monitoring reminders and verify certificate renewals.
