Certimon: The Free SSL Certificate Monitor That Never Sleeps
Have you ever experienced the panic of a website going down because an SSL certificate expired? It’s happened to the best of us. That’s why I built Certimon - a completely free SSL monitoring service that runs through Telegram and ensures your certificates never expire unnoticed again.
Why SSL Certificate Monitoring Matters
When SSL certificates expire, the consequences can be severe. Your visitors see scary security warnings that drive them away. Search engines like Google immediately downrank your site, destroying months of SEO work. Worse yet, expired certificates leave your users’ data vulnerable to interception. For businesses, even a few hours of downtime can mean thousands in lost revenue.
How Certimon Works
Certimon takes a refreshingly simple approach to SSL monitoring. Instead of complex dashboards and expensive subscriptions, everything happens through a Telegram bot. You can check any certificate instantly, set up smart reminders, and receive notifications right on your phone - all with simple commands that take seconds to learn.
Here’s what makes Certimon special:
Instant Certificate Checks
Type /check example.com and within seconds you’ll see everything about that site’s SSL certificate - who issued it, when it expires, what encryption it uses. No login required, no waiting for reports.
Smart Reminder System
Set custom alerts with /remind example.com 30 to get notified 30 days before expiry. Choose any timeframe that works for your renewal process. Certimon checks your certificates every hour, 24/7, so nothing slips through the cracks.
Unlimited Domain Monitoring
Whether you manage 5 domains or 500, Certimon handles them all for free. View all your monitored domains at a glance with color-coded status indicators showing which certificates need attention.
Built for Real People
I designed Certimon for the people who actually deal with SSL certificates:
- Developers managing multiple client projects who need reliable notifications without another dashboard to check
- System administrators tracking certificates across development, staging, and production environments
- Small business owners and startups who can’t afford enterprise monitoring solutions but can’t risk downtime either
Getting Started Takes 30 Seconds
- Open the Certimon Telegram bot
- Send
/remind yourdomain.com 30to start monitoring - Relax knowing you’ll get alerts before certificates expire
That’s it. No signup forms, no credit cards, no trial periods that expire. Just reliable SSL monitoring that works.
The Technical Details
For those interested, Certimon performs comprehensive SSL/TLS validation including:
- Certificate chain verification
- Hostname matching validation
- Expiry date tracking
- Signature algorithm analysis
- Detection of self-signed certificates
- Identification of common SSL misconfigurations
All monitoring happens from Certimon’s servers, so you don’t need to install anything or open any ports.
Free Forever, No Catch
You might wonder how Certimon can be completely free. The answer is simple: SSL monitoring should be accessible to everyone. By leveraging Telegram’s infrastructure and keeping the service focused on what matters most, Certimon remains sustainable without charging users.
Stop worrying about SSL certificate expiry. Let Certimon watch your certificates so you can focus on building great websites. Your future self will thank you the next time a renewal reminder saves you from an expired certificate crisis.
