Why SSL Certificates Matter
SSL (Secure Sockets Layer) certificates are essential for website security. They establish an encrypted connection between your browser and the server.
Encryption: SSL certificates encrypt data transmitted between users and the website, protecting sensitive information.
Authentication: They verify that you're connecting to the legitimate website and not an imposter.
Trust: Browsers display a padlock icon for sites with valid SSL, building user confidence.
Certificate Types
Domain Validated (DV): Basic encryption, verifies domain ownership only. Suitable for blogs and small sites.
Organization Validated (OV): Verifies organization identity. Better for business websites.
Extended Validation (EV): Highest level of validation with strict verification. Shows organization name in browser.
