Without a SSL, your customer information is not secure.
SSL stands for “Secure Sockets Layer”. It is a system which encrypts sensitive information input via your website (such as your customers’ credit card data) so that it is safe from hackers.
If a page is covered by SSL, it carries a “https”. For example, it shows on the left-hand side of some Amazon pages:
You may not need a SSL certificate if… :
- your website is just general information about products and services, photo galleries of you products and services, and doesn’t require your customers to login.
- you’re using payment via PayPal, you’re using PayPal’s SSL: the payment details of your customers will be safe as long as they are input on Https pages (see below example). However, some information input by your customers on “http” pages may not be safe.
- you’re selling on Ebay or Amazon, you’ll be covered by their security systems.
- your web system provides security already as standard.
You may want to buy a SSL certificate for websites with no security system or/and:
- where customers can buy online
- where there is a form with sensitive customer information
- with login requiring a user name and password
- your customers are reassured by seeing the “https” and are more likely to use your site
Some customers are reassured by seeing the “https”. You may decide to buy a SSL certificate if it means more sales on your website.
