Expired certs cause browser warnings
When SSL certificates expire, browsers display security warnings that damage trust and drive traffic away.

SSL Check
Check the SSL certificate of any HTTPS website to verify it is valid, properly configured, and not expired. MonitorMojo inspects SSL alongside uptime, response time, and security headers.

The Problem
When SSL certificates expire, browsers display security warnings that damage trust and drive traffic away.
Many teams rely on auto-renewal, but it can fail silently. Manual verification catches renewal failures.
Search engines may rank HTTPS sites lower if certificates have configuration problems.
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
Verify the certificate is valid for the current domain and date.
See exactly how many days remain before the certificate expires.
Review which certificate authority issued the certificate.
Who This Is For
Check SSL for client sites and ensure certificates are always current.
Verify SSL on maintained sites without separate certificate management tools.
Check your own SSL certificate status anytime.
Workflow Guide
Check SSL certificate status and expiry date for any HTTPS website. Verify validity, issuer, and days remaining before renewal.
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. When SSL certificates expire, browsers display security warnings that damage trust and drive traffic away. 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. Verify the certificate is valid for the current domain and date. 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 check ssl certificate: verify ssl status and expiry date — 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.
