You miss the reminders sent to an always full and often neglected department email address such as [email protected] or [email protected]’ SSL Certificate Monitoring sends you alerts about upcoming certificate expiration. You tell Uptrends how many days in advance you would like a warning, and Uptrends lets you know. Use your Alert definitions to set up reminders going to your phone, email, use an integration to apps such as Slack or PagerDuty, or use webhooks.A word about multi-year expiration datesYou can purchase SSL certificates that have expiration dates two, three, even four years into the future, but don’t do it. Although multi-year expiration dates make your life easier since you renew your certificates less often, browsers may not accept them as valid for much longer. Apple’s Safari browser is the first to enforce a one year limit on expiration dates (learn more). Starting on September 1, 2020, Safari will no longer accept certificates that expire more than 398 days out from the current date. So, your three-year certificate may still have 900 days to go before expiration, but, unless the certificate was issued before 9/1/2020, Safari will display privacy warnings to the user.You may think you don’t need to worry about Safari, but Google isn’t far behind with the same restriction in Chrome. Google has been pushing for the one-year limitation on certificate expiration for a while (Mozilla too), so you can expect announcements to come from other browsers soon. The certificate authorities have introduced subscription plans that automatically renew your certificate every year for a set period allowing you to save on your certificates. However, you will still want to set up reminders for the certificate subscription expiration, and you will want to make sure they have a current credit card number before each automatic renewal.Misconfigured certificate settings and hackersThe issuer of a certificate controls what you can and can’t do when setting up your certificate(s) and if you can make changes to your settings after the fact. Either way, once you’ve set up your regular or wildcard SSL certificate, and it is working, there shouldn’t be any reason that

We can now set up a rule to redirect all HTTP requests to HTTPS. This will redirect all HTTP requests for the website to use HTTPS instead. The wildcard SSL certificate will encrypt and secure the traffic. Step 5 – Enable HTTP Strict Transport Security (HSTS)HTTP Strict Transport Security (HSTS) is an opt-in security enhancement that forces web browsers to use HTTPS for future requests after the initial request. It prevents man-in-the-middle attacks and protocol downgrading.Enabling HSTS ensures browsers only interact with your website over HTTPS going forward. Here is how to enable it: This will set the HSTS header. You can adjust the max-age value as needed. Step 6 – Test the WebsiteThe wildcard SSL certificate is now installed and configured correctly. To test it out: If you see any issues, go back, and review the steps to ensure nothing was missed. The certificate may need to be rebound or the website restarted. Renewing the Wildcard CertificateWildcard SSL certificates are valid for 1-3 years typically. You will need to renew them periodically: Be sure to renew it several weeks or months in advance to avoid any certificate expiration errors. Troubleshooting IssuesHere are some common issues and fixes: Website showing certificate errors or warnings HTTPS site connectivity problems HTTP to HTTPS redirect not working Browsers complaining about HSTS Certificate name mismatch warnings Conclusion on Install Wildcard SSL Certificate on IIS 7 or 8Installing a wildcard SSL certificate on IIS provides an easy way to secure unlimited subdomains for your websites. Following the steps outlined in this guide, you can import the certificate, bind it properly in IIS, redirect HTTP traffic to HTTPS, and enable HSTS for maximum security.Some best practices include using a high-grade 2048 or 4096-bit encryption certificate from a trusted CA, renewing several weeks before expiration, properly securing.

2025-03-30Set up email notifications when renewal is approaching) or put it on your calendar.New Certificates are Agile CertificatesIn the world of technology, legacy is a four-letter word. I’m sure we all know some company or network running Windows XP or some other horribly outdated piece of technology. That's because it is very difficult to force people to upgrade, and supporting those old systems is difficult and often creates security vulnerabilities.A nice side-effect of certificate expiration is that it helps keep SSL practices modern.There was a point where it was possible to get certificates for five years or more. Today, the limit is three years, and the industry may be looking to reduce it even further.Shorter certificate validity makes it much easier to update security standards. Last year the entire internet migrated to the new SHA-2 signature algorithm. It was a bit bumpy because of those really old 5+ year certificates out there.From a policy standpoint, long validity periods are a nightmare. From the day a new policy was enacted, you had to wait up to five years for everyone’s current certificate to expire and start following the new standard, and in the meantime, you needed contingency plans on how to handle those that did not. In some cases that meant forcing users to upgrade mid-cycle.The CA/B Forum is an industry organization which sets best practices and standards for SSL certificate issuance. They are the ones ensuring that new certificates don't continue to use old security measures. One of the goals the CA/B Forum has been working towards is shorter certificate validity. When SSL certificates expire more frequently, it makes it easier to improve security practices.Now, that’s not to say that SSL expiration solves every problem. A huge number of servers have SSL configurations that would make most system admin’s blush. But, at least expiration keeps one part of our industry up-to-date.So, next time you are renewing your SSL certificate, remember that it’s ensuring that all the information in your certificate is accurate, proving to clients that you are still the rightful owner of the domain, and keeping your certificate’s security

SSL monitoring helps identify issues like expired, misconfigured, untrusted certificates in real-time, or other errors, ensuring that all communications remain encrypted and safeguarded against potential threats.It’s also an important part of your SEO as it’s one of the ranking factors.What does an SSL Monitoring tool do?Preventing your SSL Certificate from expiring requires proactive management and timely renewal. Setting up automated reminders or using SSL monitoring tools can alert you well before the expiration date.Many organizations opt for auto-renewal features provided by their certificate authority to ensure uninterrupted certificate validity. It's also advisable to maintain an organized record of the issuance and expiration dates of all certificates and conduct regular audits. By staying ahead of the expiration dates and understanding the renewal process specific to your certificate provider, you can ensure your SSL certificates remain active, maintaining your website's security and trustworthiness.How do you prevent your SSL Certificate from expiring?An SSL Monitoring tool, like the one offered by UptimeRobot, automates the task of overseeing SSL/TLS certificates across various systems and networks. It continuously scans and analyzes the certificates to detect anomalies, expiration dates, and compliance with the latest security standards.Providing alerts and detailed reports assists administrators in proactively managing the certificate lifecycle, preventing downtime, and maintaining adherence to security protocols. Tools like UptimeRobot's SSL Monitoring ensure that all certificates are
