How can an organization use its existing enterprise root certificate authority for SSL inspection?

An organization can utilize its existing enterprise root certificate authority for SSL inspection by generating an intermediate certificate authority from that root and uploading it to Zscaler. This approach allows the organization to create a hierarchy of trust, where the intermediate certificate acts as a bridge between the users' devices and the Zscaler service. When SSL traffic is inspected, the Zscaler service can use the intermediate certificate to sign certificate requests on behalf of the organization, making it possible for the inspection to happen seamlessly without triggering security warnings on end-user devices.

Generating an intermediate certificate authority is advantageous because it maintains continuity in the organization's existing security framework, specifically leveraging the established trust provided by the enterprise root certificate authority. This method ensures that all organizational traffic can be inspected without compromising internal security policies or trust relationships.

The other choices do not provide a viable method for using the existing root certificate for SSL inspection. Creating a duplicate root certificate does not replicate the trust relationships established with other certificates and can lead to complications. Integrating with public certificate services may not address the internal needs of the organization, as those services are often geared toward public-facing applications. Purchasing an additional certificate from Zscaler would not utilize the existing infrastructure and may increase costs unnecessarily while diminishing the organization's control over its internal
