47-Day Certificate Automation Playbook: A Practical Framework to Stop Outages and Scale Governance

September 5, 2025

In March 2026, the maximum lifespan for public TLS certificates will drop to 200 days — with 100-day and 47-day limits to follow. This will multiply your renewal rate and compress your operational windows. Manual approaches can't keep up. Short-lived certificates demand continuous renewal, cross-platform automation, and real-time visibility — not just for compliance, but to avoid costly outages. 

The CyberArk 47-Day Certificate Automation Playbook outlines a proven strategy for preparing your environment, automating lifecycle tasks, and maintaining control — before certificate chaos hits. 

This guide will cover:

  • How to lay the groundwork for automation
  • A four-step programmatic approach to certificate governance 
  • Which KPIs matter most for tracking automation readiness, SLA compliance, and renewal health
  • How to benchmark your maturity with the Certificate Automation Maturity Matrix across four levels of operational readiness
