A major d<strong>is</strong>advantage of the enterpr<strong>is</strong>e CA hierarchy model <strong>is</strong> that<br />
the benefits of secure communication are limited to the domain of the<br />
root CA. Users within the enterpr<strong>is</strong>e CA hierarchy need to<br />
communicate securely also with external entities such as customers,<br />
suppliers and business partners.<br />
The recommended enterpr<strong>is</strong>e CA model combines a well-structured<br />
enterpr<strong>is</strong>e CA hierarchy with a commercial root CA. Th<strong>is</strong> model<br />
provides a common denominator for external communication through<br />
a trusted third party, without comprom<strong>is</strong>ing the organization’s<br />
security framework.<br />
The following diagram provides an example of a combined enterpr<strong>is</strong>e<br />
and commercial CA model. Th<strong>is</strong> model enables secure transaction<br />
processing and data exchange between the sales and purchasing<br />
departments of two companies, through a common commercial<br />
root CA.<br />
