Best SSL Monitoring Tools To Choose From

Every SSL monitoring tool has different prices, features, and a range of SSL updates it can catch. But these are not the only factors we’ve considered in our list.

1. UptimeRobot

UptimeRobot SSL certificate monitoring

UptimeRobot is an advanced uptime monitoring tool that comes with many features. With UptimeRobot, you can choose from HTTP(S), keyword, ping, port, and cron job monitoring. 

While monitoring your SSL certificate, precise monitoring intervals will also let you know when your website is down, no matter the reason. 

UptimeRobot alerts you when there’s any SSL error and 30/14/7 days before your SSL certificate expires

You’ll also receive notifications via up to 12 different integrations whenever there’s something wrong with your SSL certificate.

2. TrackSSL

TrackSSL SSL monitoring

TrackSSL is a simple tool used mainly to monitor certificate expiration. It also checks for SSL changes, which include updates made to the certificate by your provider. Unfortunately, it doesn’t mention any SSL errors.

When it comes to notifications, only e-mail, SMS, Slack and MS Teams are available – but in order to use MS Teams you’ll have to upgrade to a paid plan. 

Considering the limits of this service, the monthly price is not very tempting. While the first two domains are free, monitoring 20 domains requires a $17 per month (paid annually) upgrade. To monitor 80 domains it’s $35. 

Pros Cons
✅Easy to use ❌Price
✅Nice design ❌Only 4 integrations
❌Limited monitoring

3. Sematext

Sematext SSL monitoring

Sematext offers SSL monitoring under their Synthetics service. Therefore, it is more complicated and technical, and the price is high compared to other SSL certificate expiration monitoring options.

It’s a better option when you’re looking for more feature than just an SSL monitoring. The monthly price starts at $29 for 40 monitors.

Notifications are also limited. You need to upgrade to a higher plan for $99 per month to use webhooks or ChatOps integrations (that can send alerts to platforms like Slack and PagerDuty). 

Another downside of this SSL certificate monitoring service is that support is only available for paid plans. 

Pros Cons
✅SSL errors monitoring ❌Price
✅Checks certificate authorities ❌Limited integrations
❌Complicated interface
❌Limited support

4. SSL Certificate Expiration Alerts 

SSL Certificate Expiration Alerts SSL monitoring

SSL Certificate Expiration Alerts is the most minimalistic solution available. 

You guessed it, SSL certificate expirations are the only alerts this tool can send you. You won’t get any alerts regarding updates or issues to your certificate.

Additionally, it only offers e-mail notifications. However, it is completely free

On the other hand, this means that you can’t manage and edit your alerts. The only way to remove them is through the e-mail alerts you’ll receive. 

Pros Cons
✅It’s free ❌Only expiration alerts
✅Enough for hobby projects ❌No dashboard and editing
❌Only e-mail alerts

5. Datadog

Datadog SSL monitoring

Datadog offers SSL monitoring as part of their complex and very technical monitoring service. 

Therefore, it’s also not the best option to monitor SSL expiration if you’re not interested in their other solutions. They have multiple pricing plans, which can get quite confusing for a newcomer. 

SSL certificate monitoring from Datadog starts from $5/month per 1 monitor.

One plus from Datadog is that they’ll alert you about common SSL errors. Although the interface is one of the most complex and technical out there.

Pros Cons
✅All SSL alerts ❌Very complicated
✅Detailed incident reports ❌High price

Honorable Mentions: Open-source SSL monitoring

If you enjoy preparing your own solution, here are some SSL certificate monitoring open-source solutions worth mentioning.

These two projects stand out, starting with Certificate Expiry Monitor which you can find on GitHub.

6. Certificate Expiry Monitor

Available on GitHub, Certificate Expiry Monitor is a simple project that exports the expiration dates of SSL certificates to Prometheus – an open-source project used for monitoring and alerting. 

7. SSL Certification Expiration Checker

SSL Certification Expiration Checker is simply a shell script you can run from a cron job. After it reports on expiring SSL certificates, an e-mail will be sent through Nagios to warn you. 

How to Choose the Right Tool? 

Consider these rules of thumb when choosing an SSL certificate monitoring tool.

Don’t rely on SSL expiration monitoring only. Your SSL monitoring tool should also cover updates and errors.

Make sure you’re paying a reasonable price for what you get

Monitor SSL certificates that renew automatically, they could have issues too.

Consider additional features and monitor types as a plus. Monitoring other errors associated with your URL adds great value to your SSL monitoring.

Conclusion

Don’t settle for SSL expiration alerts only. Choose the best SSL certificate monitoring tool for the right price. 

Many tools only focus on the SSL expiration date, while UptimeRobot offers you much more for a better price. Starting from 10 monitors, you’ll get up to 12 notification integrations along with many other features – including status pages and uptime monitoring.

Start monitoring your SSL certificates for just $7/month and see how simple yet effective it is.
