Purpose and Types of SSL Certificates:

As technology grows, insecurity of sensitive information and threat of hackers grows as well. Information is one of the most important asset of any organisation. SSL certification secures customer information as it travels over several computer networks. SSL is essential to safeguard your website, even if it does not have sensitive information. Without an SSL certificate your website and your visitors will be at risk. SSL certificates ensures privacy, critical security and data integrity for your website’s data and personal information of your users.

SSL Encrypts Sensitive Information

One of the prime purpose of SSL certification is securing sensitive information sent across multiple computers across the globe. SSL-enabled systems ensure that only the destination server can understand the information entered by the user. For example, when paying online you need to enter your card details – it is this that requires the highest level of safeguarding. This information travels across multiple computers in order to reach its destination server. Any computer in between is able to see your credit card numbers, usernames and passwords, and other sensitive information without SSL certificates. SSL certificates makes the entered information unreadable over the entire network except for the server you are sending information to.

Along with the encryption of the crucial information, SSL provides authentication too. This ensures the information you’re sending across is delivered to intended destination. While sending information over a network, any computer in between is able to pretend to be your website, tricking your users into sending them personal information.  This can be avoided by using a proper Public Key Infrastructure (PKI), and getting an SSL Certificate from a trusted SSL provider.

Types of SSL Certificates:

SSL certificates for websites are grouped into two categories: Validation Level & Secured Domains/Hostnames.

  • Domain Validated SSL Certificates
