Often referred to by an old name—SSL—TLS certificates are the backbone of internet security. Transport Layer Certificates protect internet connections by encrypting information sent between your browser, the website you’re visiting, and the server where the website data is stored. TLS/SSL certificates ensure that data is sent and received privately, without modification. This security also protects any sensitive information transmitted like personal data or bank account and credit card numbers, so you and your customers are protected against loss or theft.
For decades, TLS/SSL has been the standard for safe internet experience, recognized and used by all major web browsers. In addition to providing trust for websites and users, TLS/SSL also represents and certifies your website’s brand identity.
When you buy a certificate, you have the option to select the level of validation behind your site identity. More extensive validation provides higher assurance, so users know your site is really owned by you.
Domain Validated (DV) certificates provide a basic level of website security with up to 256-bit data encryption. DV certificates have the lowest level of identity validation.
Organization Validated (OV) certificates provide additional identity verification to ensure identity and brand protections in addition to strong security through encryption.
Extended Validation (EV) offers the strongest level of identity validation. EV certificates are used to deliver the highest security and assurance of brand standards.
Wildcard TLS/SSL certificates secure a single domain with the option to protect up to 250 subdomains. With flexible configurations available, any Thawte certificate can be purchased as a Wildcard. You can secure any or all of these types of domains with one certificate:
Example.com | Mail.example.com | Blog.example.com | Shop.example.com
Multi-Domain certificates, also known as SAN certificates, deliver exceptional flexibility and robust encryption for all your domains. These certificates are perfect for protecting multiple domains and subdomains (e.g., Exchange/OCS environments). They also allow you to easily add, modify, or remove SANs as needed, ensuring your network adapts to evolving requirements.
These types of certificates help reduce costs and save you time. Rather than purchasing multiple TLS/SSL certificates for each page, you purchase only one, meaning it’s easier to manage and simpler to renew.
Because major browsers require TLS/SSL security, certificates ensure that your website is searchable. When you secure your site with TLS/SSL certificates, browsers reward you by boosting findability.
Informational sites & blogs

Uses
Best for sites that don’t take payments or transmit sensitive data with HTTPS.
Best for encrypting usernames and passwords, as well as forms used to transmit personal information, documents or images.
Best for securing financial data and highly sensitive personal information, where customers need confidence to buy.
Recommended TLS/SSL certificate type
OV (Organization Validated) TLS/SSL certificates - The second highest level of authenticity and includes verification of the person or business behind the site.
OV (Organization Validated) TLS/SSL certificates - The second highest level of authenticity and includes verification of the person or business behind the site.
EV (Extended Validation) TLS/SSL Certificates - The highest level of authenticity with the most rigorous identity verification.
