The communication between the server and the site visitors is made in clear text; consequently, an attacker can intercept communications and see passwords or private information inside the website. To secure your website, you need the HTTPS protocol and SSL certificates provided by Zooku, so that the communication between the server and the visitor's browser will be encrypted.
SSL certificates also guarantee the true identity of the website. The browser checks if the certificates are signed by a recognised certification authority; in this way, you can be assured that you are visiting the website you want and have not been directed elsewhere.
Is it dangerous without SSL?
Yes, if you have visitors who use email, your online store, or your site and they are connecting from a wireless, GSM, or neighborhood network, there is considerable risk. Online hackers can easily steal passwords from these users or alter the information in their accounts.
