SSL Monitoring So a Certificate Never Expires Quietly
SSL monitoring checks your certificate on a schedule, not just whether it's valid right now, but how long it has left. Zunoy Uptime tracks expiry, chain integrity, and issuer details, and alerts you well before a visitor ever sees a browser warning.
What to Check
Check Any Certificate That Matters
Main Website
The certificate visitors see the moment they land on your homepage.
API Endpoint
A certificate securing traffic between services, not a browser tab.
Custom Domain
A client's own domain pointed at your platform, still needs its own valid certificate.
Wildcard Certificate
One certificate covering every subdomain under it, watched as a single check.
Getting Started
Start Monitoring in Under A Minute
Create your monitor
Name your monitor and select SSL as the type.
Point it at your domain
Enter the domain, and set a check interval, from every 30 seconds to once a day.
Set your alerts
Choose in-app, email, or both, and set how often to resend alerts if a check keeps failing.
Turn on Incidents
An expiring or invalid certificate opens an incident automatically, ready to be assigned and tracked.
Built-In Checks
It Checks More Than "Valid or Not"
Expiry Countdown
Know exactly how many days a certificate has left, not just whether it's still technically valid.
Chain Validation
The full certificate chain audited, not just the leaf certificate.
Issuer & Algorithm Details
See who issued it and what encryption it's actually using.
Domain Mismatch Detection
Catch a certificate that doesn't actually match the domain it's serving.
Here's Everything It Connects To
A SSL monitor has more has much more to offer. Track its workflow in the rest of the platform
Status Pages
Show Certificate Health, Not Just Uptime
Link a SSL monitor to a status page, so certificate status is visible alongside everything else you're watching.
Incident Response
An Expiring Cert Opens a Real Incident
A certificate crossing your expiry threshold triggers an incident automatically, tracked and assigned instead of forgotten in a calendar reminder.
Analysis
See Your Renewal History, Not Just Today's Status
Every check builds into a record of when certificates were renewed, and how close to the deadline it happened.
AI Features
Let AI Set It Up For You
AI SRE keeps watching in the background so a renewal never sneaks up on you.
Integrations
Alert your Team in Real Time
Connect Slack, Discord, MS Teams, Webhooks or any channel where your team is active.
Benefits
What Every Check Actually Verifies
A certificate being valid right now isn't the same as being safe for long. Here's what gets verified on every single check.
Warned before a browser warns your visitor
Days of runway instead of a red-screen surprise. That gap is exactly what turns a scramble into a routine renewal.
Catches a certificate problem early
An intermediate certificate issue gets caught too. A single weak link anywhere still breaks trust for a visitor.
Confirms the certificate matches the domain
Not just that a certificate exists, but that it's the right one. A mismatch gets rejected by browsers regardless of validity.
A renewal history you didn't have to keep yourself
Every past expiry and renewal, already on record. Useful the moment an audit or a client actually asks.
You'll Probably Want One More Check
Real Scenarios
This Is What It Actually Catches
- DEVOPS
DevOps Teams
A certificate auto-renewal script fails quietly, and the countdown alert catches it before the old cert actually expires.
- TEAMS
Compliance Teams
A documented history of every certificate renewal, ready whenever an audit asks.
- SAAS
SaaS Companies
An API integration silently breaks because a partner's certificate lapsed, and the alert tells you exactly which one.
- ENTERPRISE
Multi-Vendor Services
A dozen client domains, one dashboard, and you're the one who catches an expiry before the client does.
Quick Answers
What is SSL monitoring?
SSL monitoring checks your certificate on a schedule, tracking its validity, expiry date, and chain integrity, and alerts you before it becomes a problem.
How far in advance will I be warned before a certificate expires?
You choose the threshold, 30, 14, or 7 days before expiry, whatever gives your team enough time to renew.
Can it catch a certificate that doesn't match my domain?
Yes. Domain mismatch detection flags a certificate serving the wrong domain, which browsers reject even if the certificate itself is technically valid.
How is this different from the SSL check inside HTTPS monitoring?
HTTPS monitoring verifies the certificate as part of a broader connection check. SSL monitoring is dedicated entirely to the certificate itself, expiry countdown, chain validation, issuer details.
Does it check the full certificate chain, or just the main certificate?
The full chain, so an issue with an intermediate certificate gets caught, not just a problem with the leaf certificate.
What happens when a certificate crosses the expiry threshold?
You're alerted, and an incident can open automatically if Incident Management is turned on.
Stay Ahead
Never Miss an Expiring Certificate
Stop finding out about an expired certificate from a customer. Watch the countdown instead, days before it actually becomes a problem. Set your threshold once, and every renewal deadline takes care of itself from there.
