"Auto-renew" doesn't always mean it happened
Auto-renewal fails silently more often than expected — a billing issue, a DNS validation problem, or a host migration can all quietly break it.
SSL Monitoring Software
MonitorMojo helps you track SSL certificate expiration dates across all your domains. Each health check includes SSL status alongside reachability, response time, and security headers.

Website health signals, not live monitoring data
The Problem
Auto-renewal fails silently more often than expected — a billing issue, a DNS validation problem, or a host migration can all quietly break it.
Root domains get remembered; www, app, and staging subdomains on separate certificates are the ones that quietly expire unnoticed.
There's no gradual warning sign before expiry — the certificate is valid, then suddenly a visitor sees a full-screen browser error.
How It Works
Enter the website, subdomain, or client property you need to protect.
Run a real reachability, HTTPS/SSL, response time, and configured health check.
Use the returned signals to decide what to fix before a browser error or complaint.
Features
Confirm whether a certificate is currently valid, not just whether a renewal was scheduled.
See how much runway is left before a certificate expires, across every hostname you track.
Check root domains, www, and subdomains individually, since each can carry its own certificate.
Review SSL status next to response time and reachability, since certificate problems can look like a slow or broken site.
Pull SSL status into your own tools or automation.
Catch a certificate nearing expiry before a visitor's browser shows a security warning.
Who This Is For
Track certificate status across every client domain and subdomain, not just the ones you remember.
Add SSL expiry tracking to a recurring maintenance check.
Stop relying on renewal emails that might land in the wrong inbox.
Why MonitorMojo
A live check confirms current certificate status, catching cases where an automatic renewal silently failed.
Track certificate status across as many hostnames as needed without a fixed per-domain subscription.
Root domains, www, and subdomains are each tracked on their own, since certificate coverage often varies between them.
Workflow Guide
SSL monitoring software that tracks certificate expiration dates, verifies HTTPS configuration, and helps prevent browser security warnings across your website portfolio.
In practice, that means reviewing SSL certificate status, certificate expiry windows, renewal ownership, and post-renewal confirmation from one repeatable process instead of waiting for site owners and small teams to hear about a problem secondhand. A check can show whether a URL is reachable, whether SSL appears valid, how quickly the server responds, and whether selected headers are present — it does not replace a security audit or an incident-response team, but it makes the underlying signals visible before they turn into a bigger issue.
This is built for site owners and small teams — specifically for the moment of running a routine check before a visitor finds the problem first. Auto-renewal fails silently more often than expected — a billing issue, a DNS validation problem, or a host migration can all quietly break it. The same workflow is reusable by anyone with a public URL tied to revenue, leads, or reputation.
Start by listing the URLs that actually matter for running a routine check before a visitor finds the problem first — not every page on the site, just the ones tied to revenue, signups, or trust. Define the check types for each: reachability, HTTP status, HTTPS/SSL status and expiry window, response time, redirects, and security header presence.
Set a cadence that matches the risk: a monthly review for low-traffic pages, a check right after every deploy for anything tied to revenue. When something fails, triage before assuming cause — hosting, DNS, SSL, code, cache, or a third-party script could all be responsible. Record an owner and a next review date, then re-check after the fix ships.
Use this template for every review: [URL], [Check Type], [Status], [Issue], [Priority], [Owner], [Detected Date], [Next Review Date]. Describe what the check observed before assigning a root cause — 'response time increased' is a fact, 'hosting is the problem' is a guess until confirmed.
For a recurring report, group findings by reachability, SSL, response time, and security headers, and say plainly when a signal showed no issue rather than implying full coverage.
The most common miss for site owners and small teams is checking only the homepage while a checkout, signup, or booking flow silently breaks. A close second is assuming SSL auto-renewal always works — it can fail quietly, and an external check is the only way to catch it before a browser warning does. The biggest framing mistake is treating one clean check as proof the whole site is covered.
Picture running a routine check before a visitor finds the problem first. A scheduled check flags that a key page is slower than its usual baseline and a security header is missing. Confirm whether a certificate is currently valid, not just whether a renewal was scheduled. Instead of guessing, the team logs the observation, assigns an owner, and re-checks after the fix — turning "something feels off" into a closed-loop task with a timestamp attached.
MonitorMojo runs the checks behind ssl monitoring software for certificate expiration tracking — reachability, SSL, response time, and security headers — from one dashboard, with an API and CLI for teams that want it scripted into an existing workflow. Credit-based checks make it practical to run a review exactly when it matters: before a client call, after a deploy, or the moment someone asks whether the site is healthy.
FAQ
Auto-renewal can fail silently due to a billing issue, a DNS validation problem, or a host migration that doesn't carry the renewal setting over — a live check catches this even when the renewal email said everything was fine.
Yes. Root domains, www, and other subdomains are each checked individually, since they can be issued on separate certificates with different expiry dates.
Checks surface the expiry window directly, so you can see how much time is left rather than being caught by surprise when a browser shows a warning.
Yes. A public API is available for retrieving certificate status programmatically. Documentation is available at /api-docs.
MonitorMojo uses credit-based pricing — you pay for checks you run, which scales with however many domains you're tracking. View current rates at /pricing.
