SSL certificates are critical for website security and trust. Regular monitoring prevents expired certificates that can damage your business. Here's why SSL certificate monitoring is essential:
Expired SSL certificates expose your site to security vulnerabilities. Regular checks ensure continuous HTTPS protection and encrypted data transmission.
Browser warnings for expired certificates scare visitors away. Valid SSL certificates show the padlock icon, building confidence and credibility.
Google penalizes sites with expired or missing SSL certificates. HTTPS is a ranking factor - expired certificates hurt your search visibility.
Security warnings block visitors from accessing your site, leading to lost sales and conversions. Monitoring prevents costly downtime.
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. It ensures data transmitted between web servers and browsers remains private and secure.
SSL certificates contain the website's public key and identity information. When a browser connects to a secure website, the SSL certificate enables the encrypted link, showing the padlock icon in the address bar.
