SSL Certificates

SSL certificate for websites

SSL / TLS encrypts the SSL certificateand thus securely protects sensitive data that flows between your server and the other party. For example, between a web server and a user's browser (HTTPS). It encrypts passwords, addresses, account numbers, credit card numbers, and sensitive personal information to protect them from a third party eavesdropping.

Using of an SSL certificate should be a matter of course for all websites that collect sensitive user data. An SSL certificate increases the trust and prestige of websites and can help improve the position in the search engines.

The choice of SSL certificate depends on the kind of verification, type and price of the certificate. The prices of certificates directly reflect the prestige of the certification authorities that issue them.
