SSL Certificates for Microsoft™ IIS Web Server
Microsoft IIS Web Server SSL Certificates
Microsoft™ Internet Information Services (IIS) web servers are premium, world-class web servers. Microsoft™ has developed to offer sustainable competition to other web server marketers such as Apache, O’Reilly, and Sun Microsystems.
A wide variety of SSL certificates are capable of securing IIS web servers. IIS typically requires the use of bundled SSL certificates. Here is a list of SSL certificates that are fully-compatible with IIS web servers.
EV SSL Certificates for IIS Web Server
These certificates represent the most stringent effort to verify the legitimacy of a web site and the business or organization that owns it, to prevent online fraud. EV SSL certificates are premium SSL certificates with visible security features such as an organization name displayed on the URL while providing additional visible evidence to the web site visitors that the site is protected and the business or organization is completely validated.
