What is an SSL Certificate?
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. It's a crucial security measure that ensures sensitive data transmitted between a web server and a browser remains private and integral.
Why Check SSL Certificates?
Regular SSL certificate checks are essential for several reasons:
- Verify certificate validity and expiration dates
- Ensure proper configuration and implementation
- Check for potential security vulnerabilities
- Maintain compliance with security standards
- Build trust with website visitors
