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

✅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.

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

However, to access some of the more advanced integration features, a higher-tier plan is necessary.

Pricing might be a sticking point for some, even though there is a free plan available. Starting at $25/month (billed annually) for the most basic monitoring package, the cost escalates with the addition of more sophisticated features and higher monitoring frequencies.

Pros Cons
✅ Comprehensive SSL and performance monitoring ❌ Can be complex for beginners
✅ Vulnerability detection and configuration checks ❌ Higher-tier plans can be pricey
✅ Customizable alerts and integrations

For businesses needing tailored monitoring solutions, Smartbear provides custom pricing, which could be a hurdle for budget-conscious users.

On the upside, you can have a free trial for every one of their tools.

✅ In-depth SSL certificate analysis ❌ Custom pricing can be unclear

What Happens When Your SSL Certificate Expires?

The expiration of an SSL certificate is not just a minor inconvenience; it can lead to a series of adverse outcomes that impact both the user experience and the website’s credibility. 

Here’s what can happen if you neglect your SSL certificates.

Browser Warnings

The most immediate effect of an expired SSL certificate is the browser’s display of security warnings to visitors. This alert suggests that the connection is not secure, prompting many users to leave the site immediately to protect their data.

Decreased Trust

Trust is a cornerstone of digital interactions. An expired SSL certificate signals neglect and can significantly erode users’ trust in your brand, leading to a loss of customer loyalty and potential revenue.

Impact on Transactions

For e-commerce sites, an expired SSL certificate is particularly detrimental. Modern web browsers may block transactions, or users may choose not to proceed with purchases due to security concerns, directly affecting your bottom line.

SEO Penalties

Search engines prioritize user security. An expired SSL certificate can result in lower search rankings, reducing your site’s visibility and leading to fewer visitors.

Vulnerability to Attacks

Beyond the immediate impacts, an expired SSL certificate leaves your website more vulnerable to man-in-the-middle attacks and data breaches, compromising user data and further damaging your reputation.

Given these consequences, it’s clear that proactive SSL certificate monitoring and renewal are essential to maintaining the security, trustworthiness, and user experience of your website.

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.


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.
