SSL Monitoring Software for Certificate Expiration Tracking

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.

The Problem

Small misses turn into public failures fast.

"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.

Subdomains get missed

Root domains get remembered; www, app, and staging subdomains on separate certificates are the ones that quietly expire unnoticed.

Expiry is invisible until a visitor sees the warning

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

1

Add your domain

Enter the website, subdomain, or client property you need to protect.

2

MonitorMojo checks it

Run a real reachability, HTTPS/SSL, response time, and configured health check.

3

Review what needs attention

Use the returned signals to decide what to fix before a browser error or complaint.

Features

Website health checks built for the signals teams forget until they hurt.

verified_user

Certificate validity checks

Confirm whether a certificate is currently valid, not just whether a renewal was scheduled.

event

Expiry window visibility

See how much runway is left before a certificate expires, across every hostname you track.

domain

Every hostname, not just the root

Check root domains, www, and subdomains individually, since each can carry its own certificate.

speed

Checked alongside response time

Review SSL status next to response time and reachability, since certificate problems can look like a slow or broken site.

api

API access

Pull SSL status into your own tools or automation.

search_check

Proactive detection

Catch a certificate nearing expiry before a visitor's browser shows a security warning.

Who This Is For

Built for teams closest to the website.

Agencies managing client certificates

Track certificate status across every client domain and subdomain, not just the ones you remember.

Website maintenance teams

Add SSL expiry tracking to a recurring maintenance check.

Anyone burned by an expired certificate before

Stop relying on renewal emails that might land in the wrong inbox.

Why MonitorMojo

Simple checks for real website risk.

Checks actual validity, not just a renewal calendar

A live check confirms current certificate status, catching cases where an automatic renewal silently failed.

Credit-based pricing

Track certificate status across as many hostnames as needed without a fixed per-domain subscription.

Every hostname counted separately

Root domains, www, and subdomains are each tracked on their own, since certificate coverage often varies between them.

Workflow Guide

What this workflow means

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.

Who should use this

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.

Detailed step-by-step workflow

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.

Checklist and template

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.

Common mistakes

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.

Practical example

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.

How MonitorMojo helps

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

Questions teams ask before they check website health.

Why would a certificate expire if auto-renewal is supposed to be on?

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.

Does this check subdomains separately from the root domain?

Yes. Root domains, www, and other subdomains are each checked individually, since they can be issued on separate certificates with different expiry dates.

How much warning do I get before a certificate expires?

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.

Can I pull SSL status into my own tools?

Yes. A public API is available for retrieving certificate status programmatically. Documentation is available at /api-docs.

How much does it cost to track SSL across many domains?

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.
