What is a web server authentication certificate?

There are many types of security certificates that you can use with your website, and one of the most common is the Web server authentication certificate. This is an SSL certificate that protects both you and anyone entering your website. This is because it tells your customers who you are and it encrypts information so that it’s much harder for hackers to get a hold of confidential information stored on your website. This article will show you what a Web server authentication certificate is and why it might be right for your Internet needs.

What is a Web Server Authentication Certificate?

There are various SSL certificates. There are wildcard, extended validation and code signing certificates. While these are important, they aren’t nearly as common as Web server authentication certificates. When most people mention an SSL certificate, they are referring to this type of protection.

This certificate is issued directly to your Web server, or the server that allows people to connect to your website. While it’s most commonly used on this server, it can also be used to secure email and data servers. This means that this certificate is made to protect the vast number of people that are entering your website.

Servers to Browsers

An SSL certificate is responsible for proving the identity of your server to the user’s browser. Most browsers have security features that will warn users if the website owner is unknown. This is especially true if the person is entering credit card information. This certificate allows the browser to identify the website’s owner.

Every browser has a padlock graphic that is displayed when there is a secure connection. The Web server authentication certificate is responsible for activating this graphic. It means that the website is secure, and it also means that the user can verify the website owner’s identity. The user can click the graphic to see the name of the company, the name of the owner, the company’s address and its phone number.


While knowing the identity of the website owner is important, it’s not enough to keep people safe. Hackers are often lurking around ecommerce websites because they know that people willingly enter their credit card numbers. A skilled hacker can easily infiltrate the Web server to retrieve and abuse these credit card numbers.

A Web server authentication certificate is capable of encrypting the information to make it much harder for hackers to steal relevant information. Encryption means that the information is distorted based on a code. The only way to retrieve the information in a usable state is to know the code. The certificate ensures the hackers won’t be able to steal credit card numbers, and it assures customers because they know that they are safe.


The next major benefit of using a Web server authentication certificate is that it ensures that the user’s browser or server is authenticated. Many hackers will form a connection between you and the customer. This means that you will send information to the hacker before it reaches the customer. The certificate stops this by authenticating the server.

If the server's identity randomly changes, then the certificate will stop the transmission of information because it might be dangerous. This ensures that both you and your customers are safe during financial and data transactions.


If you want to operate an online business, then you need a Web server authentication certificate. It ensures that private information is encrypted, that all of the connections are authenticated and it proves your existence to the user’s browser. This means that people will be more willing to enter their credit card information, and it also makes it much harder for hackers to steal from you and your customers.
