This document is a guide detailing the PKI Discovery engagement offered by Entrust’s Cryptographic Center of Excellence. It outlines the challenges organizations face with fragmented public key infrastructure (PKI) and the need for clarity and coordination. The PKI Discovery engagement aims to provide a comprehensive understanding of an organization's cryptographic foundation, including visibility across technology, operations, and governance. It identifies risks and gaps, assesses readiness for evolving requirements, and offers high-level solution direction. The engagement employs a structured methodology that includes discovery workshops, analysis against best practices, and reporting of findings. The document also specifies the scope of the engagement, which includes reviewing PKI deployments and lifecycle processes, while clarifying what is out of scope, such as detailed design or implementation plans. The outcomes of the engagement include a formal PKI Discovery Report with prioritized recommendations and a roadmap for future initiatives.
