Expired Certificates Cost You Everything
Every year, thousands of websites go down because of forgotten SSL certificates. The cost? Lost revenue, damaged trust, and hours of panic.
Browser Warnings
Expired certificates trigger scary "Not Secure" warnings that instantly destroy visitor trust.
Revenue Loss
Every hour of downtime costs you customers, sales, and damages your brand reputation.
Domain Hijacking
Forgot to renew? Domain squatters are waiting to steal your brand's digital identity.
Up and Running in 30 Seconds
No complex setup, no server access needed. Just add your domains and we handle the rest.
Add Your Domains
Enter your domain names — one by one or bulk import via CSV. No server access or DNS changes required.
We Monitor 24/7
CertGuard checks your SSL certificates, TLS configuration, SAN entries, and WHOIS data automatically.
Get Alerted
Receive email notifications at 30, 14, 7, and 1 day before expiration. Fix issues before they become problems.
Everything You Need to Stay Protected
Features that no other free SSL monitoring tool offers. Built for sysadmins, DevOps teams, and agencies who need more than just expiry alerts.
Security Score (A-F)
Every domain gets an instant SSL health grade based on TLS versions, key strength, signature algorithm, and chain validation. Continuous monitoring, not a one-time scan.
Certificate Change History
Track every certificate renewal, issuer change, and TLS config update in a visual timeline. Know exactly when and what changed — no surprises.
TLS Security Warnings
Proactive alerts when TLS 1.0/1.1 is still enabled or weak configurations are detected. Critical issues flagged instantly — no other free tool does this.
Calendar Feed (iCal)
One URL — drop it in Google Calendar, Outlook, or Apple Calendar. All your cert and domain expiry dates, synced automatically with smart reminders.
Embeddable SSL Badge
An SVG badge showing your SSL grade for your README or website. One line of markdown or HTML — free trust signal for visitors, free marketing for you.
WHOIS & Domain Monitoring
Track domain registrar, expiry dates, and renewal countdowns. Included free on all plans — most competitors charge extra for this.
See Everything About Your Certificates
More than just expiry dates. CertGuard gives you a complete view of your SSL security, TLS configuration, and domain health — all in one dashboard.
