For just about any site, you probably need an SSL Certificate. Secure Socket Layer (SSL) provides safe communication via the internet. SSL Certificates protect sensitive information with encryption techniques when transmitting information between a web server and a web browser. Millions of websites use SSL Certificates on their site to keep their customers' and their visitors' information safe. Your visitors will notice that your site is protected by an SSL Certificate because your website URL will begin with HTTPS as opposed to HTTP. Additional signals of a site being secured by HTTPs is the padlock in the browser bar and a green extended validation bar found in more advanced SSL Certificate options. Some SSL Certificates also offer you a secure site seal for you to publish to signify to your visitors that your website is safe and their information is safe from potential attackers.

An SSL Certificate is installed on a web server to authenticate your website's identity. This means that the website is what it claims to be. In other words, it proves your identity to your visitors so they can be sure they are seeing your site, and not a fake or bogus website.

The other key function of an SSL Certificate is that it encrypts the data that is transmitted between the server containing the site and your visitors. This prevents data being sent between your website and your visitors from being read by anyone else.

Absolutely! In Google Chrome, if your site is not protected by an SSL Certificate, your visitors will get a warning message that your site is "Not Secure".

SSL certificates are strongly recommended if you have a website that receives or transmit any sensitive information like credit card numbers, license numbers, social security numbers etc. They are also strongly recommended for any pages where a password is submitted. While SSL Certificates especially important in these instances, it has become more evident recently that all sites should actually be SSL protected. That's because many browsers have started to flag sites that are not using the SSL/HTTPS protocol for being unsafe. Protecting your site with an SSL Certificate can prevent you from having this distinction. 

Additionally, buying an SSL Certificate for your site is one the easiest and fastest ways you can boost your SEO rankings. That's because part of Google's algorithm is whether your website can be considered trustworthy or not. In short, having an SSL Certificate for your site is the new standard as they provide a secure connection from your site's server to your visitors' browsers.

When your website's audience visits your site, their browser checks for and views your SSL Certificate. Your visitors' computer confirms your site's identity through your SSL's Certificate Authority, the organization that issed the digital certificate.

If everything checks out OK, your visitors' computer and the server your website is hosted on perform a digital "handshake". This is when the computer and your server determine what sort of encryption will be used to create a secure connection. This is known as the Secure Socket Layer, or SSL. The flow of data between the computers is encrypted, meaning it is jumbled up into a code to prevent unauthorized viewing. Your visitors' browser will display some sort of identifer, usually a padlock, indicating to your visitor that a secure connection with your website has been made.

Los certificados SSL son otorgados por una entidad de certificación (Certificate Authority o CA). El trabajo de esta entidad es verificar que el propietario del sitio Web es en realidad quien dice ser. Una verificación de empresa puede también ocurrir si el sitio es de propiedad de una empresa, probablemente una tienda de comercio electrónico. Una copia del certificado SSL es recibida una vez que la CA verifica al propietario del sitio. El propietario del sitio Web es entonces libre de instalar su certificado SSL en el servidor de su sitio Web.

Una vez que el explorador de su visitante accede al servidor Web que hospeda a su sitio, tiene lugar un “protocolo de enlace SSL”. Esto significa que el explorador y el servidor han establecido una llave que informa a ambos que la comunicación es segura y que el certificado SSL es de hecho válido. Lo más importante es que sus visitantes también sabrán que cualquier información que sea transmitida a usted, sea una contraseña, número de tarjeta de crédito o número de seguro social, estará segura gracias al uso del certificado SSL.

An SSL Certificate allows your site to move from HTTP to the safer Hypertext Transfer Protocol Secure (HTTPS). The use of HTTPS helps protect your visitors' connections made to your site and avoid what is known as "man-in the-middle" attacks. This type of attack, where sensitive communication/information is intercepted and de-crypted, can be protected against with the use of an SSL Certificate. 

You should have one SSL certificate to protect each of your websites. With that being said, if your site has multiple subdomains (i.e domain1.a2hosting.com, domain2.a2hosting.com etc.), you should consider a Wildcard SSL. That's because a single Wildcard SSL Certificate can protect unlimited subdomains.

A2 Hosting also offers multi-domain SSL certificates. This SSL solutions protect multiple domains with a single certificate.
