Smart SSL/TLS Certificate Expiration Tracking
SSL/TLS certificate expiration is one of the most preventable incidents in infrastructure. Yet it happens constantly. Teams get distracted, processes break down, and suddenly you're explaining to customers why their browsers are showing security warnings.
ZoneWatcher now prevents this.
The Problem
Traditional certificate monitoring is noisy. You set a threshold and you get alerts at that threshold. 30 days out, you get an alert. 14 days out, another alert. The problem is, you might have already renewed. Now you're ignoring alerts because half of them are for certificates that are no longer a risk.
That's alert fatigue. That's why renewal reminders end up in a folder you never check.
The Solution
Our new Smart Certificate Expiration Tracking uses Certificate Transparency logs to monitor when replacement certificates have been issued. Here's how it works:
You get proactive alerts at 7, 5, 2, and 1 day before expiration. But here's the smart part: if a replacement certificate has already been issued for the same set of domains with the same issuer, we suppress those alerts. You only hear about expirations that actually need action.
It's the difference between being notified about problems and being notified about things that require your attention.
Built Into Your Monitoring
This isn't a separate tool. It integrates directly with your ZoneWatcher DNS monitoring. The same interface that shows you record changes now shows you certificate status and renewal readiness.
You get a single pane of glass for your entire domain infrastructure: DNS records, nameservers, and certificates. All monitored. All integrated.
For organizations running dozens or hundreds of domains, this approach scales. Each domain gets the right level of attention based on whether the renewal has actually been issued.
