TLS/SSL Certificates

Secure your website, improve your brand, and boost visitor trust with TLS/SSL security.

TLS/SSL fundamentals

What are TLS/SSL certificates?

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.

Why should you secure your site with TLS/SSL certificates?

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.

Higher validation, stronger 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


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


Organization Validated (OV) certificates provide additional identity verification to ensure identity and brand protections in addition to strong security through encryption.

Extended Validation


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 vs. Multi-domain certificates

What is a Wildcard certificate?

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

What is a Multi-domain certificate?

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.

What is the advantage of a Wildcard or Multi-domain certificate?

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.

Improve your website SEO

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.
