SSL certificates are an effective way to add trust and security to a website or digital application or to ensure the safety of an on-line tranzaction or on-line communication. A website that has its own SSL certificate confirms its identity to the end-user browsing on the website and adds an extra layer of security to the transactions made through the website. Depending on the type of ceritificate chosen you might have to provide extra details other than those provided at the time of the purchase in order to confirm your identity, your address or company information if that is the case.
