CLM 101: Your Ultimate Guide to TLS Certificate Management

July 31, 2025

Organizations are racing to meet the new 47-day TLS certificate lifecycle mandate — a game-changing shift that drastically reduces certificate validity periods and increases the pressure to automate. Yet many teams remain unprepared, relying on outdated, manual certificate processes that can lead to outages, security gaps, and audit failures.

While businesses invest billions in identity and access management (IAM), nearly all of that spend is focused on human identities — usernames, passwords, and multi-factor authentication. Meanwhile, machine identities like TLS certificates, which secure everything from APIs to cloud workloads, often go unmanaged and underfunded.

This comprehensive guide explains why TLS certificate lifecycle management (CLM) is critical to modern cybersecurity — and how you can get ahead of new mandates before they impact your business.

What You’ll Learn in This Guide

  • What TLS certificates do and why mismanaging them puts your entire enterprise at risk
  • How the explosion of machines is straining legacy CLM approaches — especially with shorter certificate lifespans, complex cloud architectures, and agile DevOps workflows
  • The real security risks tied to poor CLM, including unplanned outages, shadow issuance, and audit exposure
  • The most common challenges organizations face with CLM — and why they often go beyond technical issues
  • Why automation is no longer optional, especially in light of the 47-day certificate renewal window
  • A practical 4-step framework for designing and implementing an automated TLS certificate lifecycle program that scales
