This document discusses the benefits of using a PKI Box for implementing a public key infrastructure (PKI). A PKI Box simplifies and speeds up the PKI implementation process, reducing effort from months to weeks. It allows organizations to have their own internal certificate authority and has been successfully used in hundreds of critical implementations worldwide. Using a PKI Box such as the PrimeKey PKI Appliance or SecureMetric PKI Box can significantly reduce costs compared to traditional PKI solutions.
