Public Key Infrastructure (PKI) has been the bedrock of digital trust for decades. However, the nature of our digital world has changed dramatically. The explosion of cloud services, IoT devices, and fast-paced DevOps cycles has created an environment where traditional, manual PKI management is no longer sufficient. The sheer volume and short lifespan of certificates can quickly become overwhelming, leading to manual errors, security gaps, and costly outages.

This is where Next-Generation PKI, or PKI 2.0, comes in. It's not a replacement for the core principles of PKI, but an evolution in how we manage it. Next-Gen PKI prioritizes automation, agility, and visibility to handle the scale and speed of modern IT environments. It treats machine identities—like TLS certificates and SSH keys—as critical assets that require automated lifecycle management, just like any other piece of infrastructure.

Building a robust Next-Gen PKI requires a combination of specialized tools that work in concert. In this course, we'll focus on an integrated solution using three key components, each playing a distinct and vital role.

Thales Luna HSM: This is the root of trust in our architecture. The Thales Luna Hardware Security Module (HSM) provides a FIPS 140-2 Level 3 certified environment for generating, storing, and protecting the private keys of your Certificate Authority (CA). By keeping these critical keys in a dedicated, hardened appliance, you ensure they are never exposed to software-based attacks.

Venafi Trust Protection Platform: This is the control plane and automation engine. Venafi provides a centralized platform for discovering all certificates across your network, enforcing security policies, and automating the entire certificate lifecycle. It integrates with your CAs, HSMs, and application endpoints to issue, renew, and provision certificates without human intervention.

Azure Key Vault: This is our secure storage and management service in the cloud. Azure Key Vault is a cloud service for securely storing and accessing secrets, keys, and certificates. In our setup, it serves as a secure repository for certificates needed by cloud applications, integrating seamlessly with Venafi to extend automated lifecycle management into the Azure ecosystem.

Together, these three components create a powerful, end-to-end solution. Venafi acts as the brain, discovering certificate needs and enforcing policy. It communicates with the Thales HSM to ensure the root private keys are used securely for signing operations. Finally, it provisions the issued certificates to where they are needed, whether that's an on-premise server or securely stored in Azure Key Vault for cloud-native applications.

This course is designed to provide you with the practical skills to build and manage a modern PKI. By the end, you will be able to:

• Integrate a Thales Luna HSM with the Venafi Platform to establish a hardware-backed root of trust.
• Automate the complete certificate lifecycle, from request and issuance to renewal and revocation, eliminating manual processes.
• Utilize Azure Key Vault as a secure and integrated certificate repository for cloud workloads.
• Design and deploy a resilient and scalable PKI architecture that can meet the demands of a dynamic enterprise environment.
