Public TLS certificate lifetimes are shrinking dramatically, from today's 398 days down to just 47 days by March 15, 2029 (with phased reductions starting in 2026). In Microsoft Windows enterprise environments, manual certificate management creates a heavy administrative burden and poses frequent outage risks due to missed renewals. This session delivers practical automation strategies for public TLS certificates on Windows, leveraging native features and leading third-party tools and services to transform short-lived certificate challenges into reliable, hands-off resilience.

You will learn:

  • About ACME certificate enrollment
  • How to manage short-lived TLS certificates in Windows
  • How to use free and commercial certificate management solutions
