What is an SSL used for?

The primary purpose of an SSL is to keep the information between a website and its users encrypted so only they are able to read it. This is important because when information is transmitted across the internet it passes through many different computers all of which can read and record it.

That means that any computer between you and the website can read credit card details, usernames and passwords. When an SSL is this information becomes unreadable to those computers.

In addition to this encryption an SSL also provides authentication ensuring that a user is sending information to your website and not that belonging to a criminal. Again, because information passes through many computers without an SSL any of these could impersonate your website and trick users into sending their personal details.

Why is an SSL needed on my website?

Ecommerce sites are required to transmit and receive sensitive information including credit card and contact details. Most websites provide administrators with the ability to edit content through a log-in area that requires a username and password to access. In both cases if an SSL is not used that information can be stolen by a third party and be used for criminal means.

Do I need an SSL if I don’t run an ecommerce shop?

There are numerous reasons why an SSL is beneficial even if your website is not ecommerce and does not have a log-in/administration area.Anchor


Google stated in 2015 that they are using the presence of an SSL on a website as a ranking signal. That is, a website with an SSL will rank above a website without all things being equal. Continuing into 2016 Google will place more and more emphasis on an SSL as a factor. Furthermore Google has plans to alter its chrome browser to show websites without an SSL as “insecure” which could serve as scare tactics pushing potential customers to a rival.

Integrity of the content you are serving on your website

Once you secure your website with an SSL certificate a third party cannot alter the content that is going to be received by the end user. Here you can assure your website visitors that the content they are viewing is the same as you are publishing. Without an SSL a third party can alter the content of your website before it is received by adding adverts or more dangerous content such as viruses.

Authentication of the Website and its content

An SSL verifies that you are who you say you are. A website secured by an SSL and verified by certificate authority means your customer can easily recognize that the information is genuine and not from someone else. This is especially important if your website contains content such as technical specifications, health, finance or other information of this nature.

A signal of trust to the user

Web browsers give a visual indicator when a site uses an SSL. While they may not be aware of exactly how it functions users know that the padlock logo that appears on an SSL enabled site is “good”. The use of an SSL tells users of your website that you consider their security and privacy to be important.
