The two terms are often used interchangeably in the industry although SSL is still widely used.When you buy an 'SSL' certificate from Symantec, you can of course use it with both SSL and TLS protocols.Certificates can be divided into three authentication groups, based on the level of authentication, which are: These require businesses to prove their control over just the domain name.The certicate contains the domain name that was supplied to the issuing authority as part of the request.The basic principle is that when you install an SSL certificate on your server and a browser connects to it, the presence of the SSL certificate triggers the SSL (or TLS) protocol, which will encrypt information sent between the server and the browser (or between servers); the details are obviously a little more complicated.SSL operates directly on top of the transmission control protocol (TCP), effectively working as a safety blanket.It's an essential way of making sure sites are secure and customers are protected, but crucially it also adds the appearance of security to online sites.
Depending on what level of validation a certicate is given to the business, a secure connection may be indicated by the presence of a padlock icon or a green address bar signal.
The details of the certificate, including the issuing authority and the corporate name of the website owner, can be viewed by clicking on the lock symbol on the browser bar.
Compare SSL Prices For online businesses or websites which accept credit or debit card payments, or involve the transfer of personal or sensitive information such as names and addresses, an SSL certificate is a necessity for website security.
Google now advocates that HTTPS, or SSL, should be used everywhere on the web and, as of 2014, the search engine has been rewarding secured websites with improved web rankings, another great reason for any site to install SSL.
Transport Layer Security (TLS) is the successor protocol to SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information.EV SSL requires both of the above validations for domain and company as well as several additional verication steps related to proving that the SSL certicate belongs to a registered company.
