About 47DayCerts

Hey, I'm Ramesh.

For 14 years I worked in SSL and PKI. Certificates, audits, outages, renewals. I've seen what happens when something small breaks trust on a large scale.

Now the web is about to change again. By 2029, SSL certificates will last just 47 days. That means automation stops being a convenience and becomes survival.

I built 47DayCerts to help teams see what's coming. You enter your domain. It scans your certificate setup and gives you a readiness score, a full renewal timeline through 2029, and alerts when it's time to renew.

Checking any domain is free forever — no signup, no limits. Continuous monitoring across many domains is a paid tier that funds the service. No funding, no investors, no sales team. Just a tool I built because this industry gave me 14 years of career and I wanted to give something back.

If this helps you avoid even one outage, it's worth it.
