Why it matters
An expired certificate takes your whole site down
A lapsed SSL certificate doesn't slow a site — it stops it. Traffic, signups, and checkouts halt the moment the browser refuses to trust your domain. Monitoring SSL certificate expiration is the difference between a calm renewal and an outage.
100%
of visitors are blocked
The instant a certificate expires, browsers throw a full-page security warning and stop people reaching your site.
Weekends
are when certs quietly lapse
Expiry dates rarely land on a convenient Tuesday. Without monitoring, you find out from an angry customer.
Dozens
of certs per team to track
Between client sites, subdomains, and internal tools, manually remembering renewal dates simply doesn't scale.
What we monitor
Everything an SSL certificate monitoring tool should watch
Uptura tracks the expiry, issuer, trust, and TLS version of every certificate on every check — and routes any warning straight to email and Slack.
Expiry countdown & renewal alerts
Track the exact expiry date of every certificate and get an early reminder as it approaches — so a renewal never slips past you.
Issuer & trust validation
On every check Uptura reads the issuing CA and validates that the certificate is trusted — so an untrusted or broken chain is caught immediately.
Unified alerting
Route certificate warnings to email and Slack alongside your uptime and DNS alerts — one stream, no separate tool to check.
TLS version & protocol health
Read the negotiated TLS version on every check and alert the moment it's downgraded to a weaker, outdated protocol — before a scanner or a customer's browser flags it.
How it works
Set it once, then stop thinking about renewals
SSL expiry monitoring shouldn't be a chore. Point Uptura at your domains and it handles the watching from there.

Add your domains
Point Uptura at the sites and endpoints you manage. It discovers the certificate on each hostname automatically — no agents, no manual cert uploads.
- 2
We check on a schedule
Uptura inspects each certificate around the clock, reading its expiry date, issuer, and trust status on every run.

You get alerted early
The moment a certificate nears expiry or something about it changes, we notify your team — with enough lead time to renew calmly, not in a fire drill.
One platform
SSL is just one signal Uptura watches
A certificate is only healthy if the site behind it is too. Uptura pairs SSL certificate monitoring with uptime, DNS, SEO, performance, accessibility, and more — so every part of a website's health lives in one dashboard and one alert stream.
Uptime Monitoring
Around-the-clock scheduled checks catch outages the instant they happen — before your customers do.
DNS Monitoring
Watch DNS records for unexpected changes, hijacks, and misconfigurations in real time.
API & Endpoint
Test REST endpoints for status codes, latency, and JSON validity — and watch business-critical endpoints separately.
SEO Monitoring
Catch metadata, canonical, robots.txt, and sitemap regressions that quietly tank rankings — the moment they ship.
Core Web Vitals
Track LCP, CLS, and TBT over time with PageSpeed Insights scans, and get alerted when performance regresses.
Synthetic & Forms
Run scripted checks on logins, checkouts, and contact forms so broken user journeys never go unnoticed.
Visual Regression
Capture daily screenshots and highlight visual differences between deployments before anyone else spots them.
Accessibility
Continuous WCAG and Axe scans with historical reports, so accessibility regressions get caught — not shipped.
Plus everything else that keeps a website healthy
- Domain & WHOIS monitoring
- robots.txt monitoring
- Sitemap monitoring
- Broken link scanner
- Lighthouse scans
- Screenshot diffing
- Deployment comparison
- Email & Slack alerts
- Daily digests & PDF reports
FAQ
SSL certificate monitoring, answered
What is SSL certificate monitoring?
SSL certificate monitoring is the practice of continuously checking the SSL/TLS certificates on your websites for expiry, misconfiguration, issuer changes, and validity. Instead of remembering renewal dates manually, a monitoring tool inspects each certificate on a schedule and alerts you before anything lapses — so visitors never hit a browser security warning.
How do I monitor SSL certificate expiration?
The reliable way is to have a tool check each certificate's expiry date automatically and warn you well ahead of the deadline. With Uptura you add your domains once, and it tracks the exact expiry date of every certificate, sending an early reminder as expiry approaches across all your sites at once.
How can I check when an SSL certificate expires?
You can check a single certificate's expiration date in a browser by clicking the padlock and viewing the certificate details, or with a command-line tool like openssl. That works for one site on one day — but to keep dozens of certificates from expiring, you need continuous SSL expiry monitoring that watches every domain and alerts you automatically.
How can I continuously monitor SSL certificates across many sites?
Continuous monitoring means every certificate you manage is re-checked on a schedule, not just when you remember to look. Uptura is built for exactly this: agencies and teams add all their client and internal domains, and every certificate is watched side by side in one dashboard with a single alert stream.
Is there a free SSL monitoring tool?
Yes. Uptura includes SSL certificate monitoring in a complete website operations platform, and it's free during our public beta — no credit card required. Create an account, add your domains, and every certificate is watched automatically with expiry alerts.
What happens when an SSL certificate expires?
When a certificate expires, browsers show a full-page security warning and block access to the site, which halts traffic, signups, and sales instantly. Search engines and integrations may also stop trusting the site. SSL expiry monitoring exists to make sure that moment never arrives unannounced.
