Digital Tools

There are different types of SSL certificate. Find out which is the most suitable for your web project.

As we have already mentioned in previous articles, the SSL (Secure Socket Layer) certificate is a standard protocol that aims to keep a secure Internet connection between two systems and thus protect users’ information.

If you are thinking of having a website, it is mandatory that you think about the security of your own data and the security of those who visit it.

The “secure” notice, with the closed padlock icon, has become an obligatory on websites because hacking, data theft and identity theft have multiplied.

If the website does not have an HTTPS security protocol, an “Information” or “not secure” warning icon or a red triangle with the “!” symbol will appear indicating that “It’s Not Safe.”

Collaterally and due to these warnings, your site will rank better in Google if you give them reliability with a security certificate, because more users will access it.

SSL certificates are issued by a Certifying Authority, some of those companies are RapidSSL, GeoTrust and Symantec.

How to choose an SSL Certificate

Depending on the size, grade and reliability of security you want for your website, you can choose between these different types of certificate:

SSL Certificates with Domain Validation (DV)

It is a basic security level certification. Ideal for personal websites or blogs. Only the right to use a certain domain name is checked.

SSL Certificate with Organization Validation (OV)

Recommended for small or medium business websites; it is considered with an intermediate level of security. The certifying authority verifies if the company has the right to use the domain, and additionally the identity of the company that owns the domain.

It validates the security of the site and the physical existence of the company, since it also provides us with its information in the certificate. This visibility increases the level of confidence.

SSL Certificate with Extended Validation (EV)

For large companies and virtual stores, which handle sensitive information such as credit cards, bank accounts, ID, etc., the level of security is high. The company and the site are rigorously identified. The protocol is determined by the Forum of Browsers and Certification Authorities (

The right to use the domain, the physical and legal existence of the company and if it is properly registered are verified. Reliability on the site must be absolute.

Certificates depending on the number of domains you want to protect.

Wildcard certificate: protect your website and an unlimited number of subdomains.

Certificate for multidomains: allows multiple domains to register the same certificate. The issuing company is the one that determines the limit number.

Certificate for single domain: allows only one certificate per domain.

As a recommendation, you have to be cautious and before requesting an SSL Certificate, carefully plan your objectives and your work plan, to choose the one that best suits the purpose, structure and size of your website.
