15 Tools for Effective SSL Certificate Expiry Monitoring

Without active SSL certificates, communication between the website and the user is no longer encrypted, meaning any malicious party can get access to sensitive user data. However, it is unlikely that users will continue using the website after seeing a security warning, e.g. it is known that 85% of shoppers avoid unsecured websites. Using an effective, automatic SSL certificate expiry monitoring tool is the easiest way to keep track of your site certificates’ validity. 

When you have a monitoring system, you are notified of the months or days left until your SSL certificate expires. This automatic system provides you with a dashboard that contains all relevant information about your license and alerts you to revalidate your website’s certifications before or as soon as they expire. Also, some tools, such as TrackSSL alert you whenever a new SSL Certificate is changed, renewed, and issued for your domain. However, not all SSL certificate monitoring tools are equal. There are monitoring tools that send alerts before the actual expiry date, while others will simply show that the website is down due to SSL certificate expiry. Moreover, some tools that are specifically developed to track SSL certificate expiry will simply send you a series of alerts, whether or not you’ve renewed the certificate. Tools that are not designed primarily for SSL certificate monitoring often do not provide information about the certificates themselves. If you want more transparency into SSL certificates and advanced features on monitoring – sign up for TrackSSL for free.

Otherwise, here’s a quick side-by-side comparison of the 15 most popular tools that help you not miss the SSL certificate expiry date.

TrackSSL keeps tabs on your SSL and TLS certificates and expiry dates. This platform helps you track all SSL certificates used by your organization’s domain, services, and applications, and checks for unusual changes, fraudulent certifications, weak signatures, and other issues on the website. 

TrackSSL immediately notifies you when a website’s SSL certificate is updated or replaced. Users can receive notifications via SMS, email, Slack, and Teams. Additionally, alerts can be set up for separate users depending on the certificates they monitor. The cadence of the individual alerting can also be set up.

Among other features that are rarely available with other tools, TrackSSL offers bulk adding and management of SSL certificates.

TrackSSL Pricing for SSL Certificate Monitoring

TrackSSL is free if you’re operating a small-scale business with less than three domains to track.
