If you're serious about doing business online, you need SSL. It's the best way to protect user data and defend against identity theft. Many customers will refuse to do business with a website that doesn't have an SSL certificate. Displaying your SSL Site Seal tells customers they can shop with confidence, knowing they're protected. Different certificates provide different levels of validation.
Domain-level validation is the most basic type of SSL. These certificates provide basic encryption, are issued very quickly and involve a simple check to verify domain ownership. Domain-validated certificates are generally the least expensive.
Organization-validated SSL certificates include authentication of the business or organization behind the domain. This provides a higher level of security and lets customers know they can trust your server with their personal information.
