SSL certificate expiration monitoring
Understanding SSL Certificate Expiration Monitoring
In 2024, there are over 292 million active SSL certificates used worldwide. These certificates, issued by various Certificate Authorities (CAs), include a massive number from Let’s Encrypt, which manages about 301.1 million active certificates and issues around 3.16 million new ones daily.
Since SSL certificates typically last around 397 days, many expire daily. For Let’s Encrypt alone, 1 to 1.5 million certificates need renewal daily. However, many website owners must remember to renew their certificates, leading to problems like website downtime, security vulnerabilities, and loss of customer trust. High-profile cases like LinkedIn and the US government have faced significant disruptions due to expired certificates.

Despite the importance of timely renewal, human error often leads to expiration, primarily in organizations that need automated systems.
What Are SSL Certificates?
SSL certificates authenticate a website’s identity and encrypt data between the site and the user’s browser. This encryption keeps sensitive information like credit card details and login credentials secure from malicious actors.

- Data Encryption: Data encryption makes data unreadable to unauthorized users by encoding it.
- Authentication: Verifies the legitimacy of a website.
- Trust and Credibility: Displays a padlock icon in the browser, signaling a secure connection.

What Happens When an SSL Certificate Expires?
For WordPress sites, expired SSL certificates can cause significant issues:
- Security Warnings:
- Browsers display warnings about unsecured connections, deterring users.
- These warnings disrupt the user experience and can increase bounce rates.
- Loss of Trust:
- Expired certificates make a site look neglected, reducing user trust.
- Data security concerns arise since the connection is encrypted with a valid certificate.
- Search Engine Rankings:
- Expired certificates can lower search engine rankings, reducing organic traffic.
- The combination of lower rankings and browser warnings can lead to a significant traffic loss.
