Perot Systems implemented PKI for enhancing authentication for remote access. Perot Systems soon found that PKI could be used to extend authentication to applications in order to enable email encryption for confidentiality, digital certificates for nonrepudiation, and eForms to eliminate paperwork and expedite processing.

Perot Systems used PKI to authenticate users and devices as part of the VPN network for server-to-server virtual private networking, Intranet, and Extranet, and client-to-server virtual private networking for remote access employees. Perot Systems PKI was also used with other directories and network resources to enable a greater level of identification for users and network devices.

Perot Systems learned many lessons from its PKI rollout. What should it have done differently?
