About SSL/TLS Certificates
Why SSL Certificates Matter:
- Encrypts data between user and server
- Verifies website authenticity
- Required for HTTPS and modern browsers
- Improves SEO rankings
- Builds customer trust
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) certificates protect sensitive information by encrypting data transmitted between a website and its visitors. Regular SSL monitoring helps prevent security warnings and service interruptions.
Best Practices
- Renew certificates at least 30 days before expiration
- Use certificates from trusted Certificate Authorities
- Enable automatic renewal when possible
- Monitor certificate expiration dates regularly
- Use TLS 1.2 or higher for security
