You need an SSL certificate in the following cases:

• you have a web shop
• you accept credit/debit card payments (or other forms of payment)
• you provide an online service for which your subscribers pass a sign-up process
• your website requires the entry of user log-in information
• you transfer private data online
• you want to inspire confidence with your visitors and users

SSL certificates are usually selected on the basis of the type of website and your visitors.
If credit/debit card numbers and other valuable information is entered anywhere on your website, we recommend the EV certificate, which provides maximum protection and security.
The DV certificate is usually acceptable for any other requirements.

No. Every certificate is linked to a specific domain.
A partial exception are the Wildcard certificates, which cover a domain and all its subdomains.

An SSL certificate is a cryptographic protocol which increases the level of online data security between visitors of a website and the server where the site is located. In other words, SSL is the encryption of data from readable text to coded text which can be read only by using a decoding key. This enables secure communication and protection of the user’s confidential personal information and financial data.

There are three types of SSL certificates, differing in the level of protection they provide and the way they are displayed in the browser.

• DV (domain validation) – SSL certificate that protects the domain and its owner. It’s displayed in the form of a padlock + https://name.domain
• OV (organization validation) – SSL certificate that verifies and protects company data. It’s displayed in the form of a padlock + https://name.domain
• EV (extended validation) – SSL certificate that provides maximum protection. It’s displayed in the browser as a long green bar containing the company name.

Quite easily. If you hold an SSL certificate, your website address will begin with “https://” and have a padlock icon, and a “Secure” mark will appear in the browser, as shown in the image below.

When a browser displays the website as secure, the user is confident that your website is credible.

Of course.
MyDataKnox doesn’t implement that kind of limitation; you can buy the certificate and install it on a server that is not one of ours.

SSL certificates are used for protecting the data between the visitor and the server where the website is located. This means that SSL certificates enable safe online credit/debit card payments, protect the domain and company location information.
