SSL certificates come in various types, each catering to different security needs. Domain Validation (DV) certificates offer basic encryption, ideal for personal websites. Organization Validation (OV) certificates provide higher assurance by verifying the organization behind the site, suitable for small businesses. Extended Validation (EV) certificates offer the highest level of trust, displaying a green address bar and undergoing rigorous vetting, perfect for large corporations. Wildcard SSL certificates secure a domain and its subdomains, offering flexibility for businesses with multiple subdomains. Choose the SSL certificate that aligns with your website's security requirements to ensure data protection and build trust with your users.
