Public Certificate Authorities are retiring dual-purpose TLS certificates — a shift that impacts mTLS, APIs, IoT devices and any workflow relying on public certificates for client authentication. As the industry moves toward single-purpose certificates, organizations must assess where dependencies exist and how to prepare.
This guide explains what’s changing, why it matters, and how to evaluate your environment without exposing sensitive implementation details. It also highlights why this moment is an ideal opportunity to modernize your PKI, strengthen governance, improve agility and efficiency, and reduce the operational burden of manual certificate management.
What You’ll Learn:
- The security and ecosystem drivers behind the deprecation of dual-purpose TLS certificates
- How to identify which applications, mTLS workflows and devices may be affected
- Steps to validate certificate usage and uncover hidden dependencies
- High-level guidance for transitioning to private PKI and automated lifecycle management
- How modern PKI automation improves governance, agility and long-term efficiency
Who Should Read This Guide
- Security, IAM, and PKI leaders preparing for certificate policy changes
- Teams responsible for mTLS, API security, IoT, and service-to-service authentication
- Architects modernizing PKI, Zero Trust, or machine identity strategies
- DevOps and platform engineering teams managing certificates in dynamic environments
- Compliance and risk leaders seeking stronger governance and crypto-agility
