Navigating the Future of Certificate Lifecycle Management: Urgency, Automation, and Opportunity

Executive Summary

The world of digital certificates is undergoing a seismic shift. With new industry mandates, the rise of quantum computing, and the relentless pace of digital transformation, organizations must rethink how they manage the lifecycle of their certificates. This blog explores the latest changes in certificate lifecycle management (CLM), why automation is no longer optional, and how technology leaders can turn these challenges into opportunities for operational excellence and client engagement. Drawing on insights from Sayers Sr. Cybersecurity Architect, Joe Schnell’s recent presentation and the collective experience of the Sayers team, we’ll break down what’s changing, why it matters, and how to prepare for what’s next.

Introduction: Why Certificates Matter More Than Ever

Every time you see that reassuring padlock in your web browser, you’re witnessing the power of digital certificates. These cryptographic credentials are the backbone of trust on the internet and within enterprise networks. They enable secure communication, authenticate users and machines, and underpin everything from online banking to internal business applications.

But as Schnell emphasized, the landscape is changing fast. New deadlines, security threats, and operational demands are converging to make certificate lifecycle management a top priority for organizations of all sizes.

The Basics: What Are Certificates and Why Do They Matter?

At their core, digital certificates are about trust. Issued by certificate authorities (CAs), they assure browsers, devices, and users that a website or system is who it claims to be. Certificates also enable encryption, ensuring that data exchanged between systems remains confidential and tamper-proof.

But certificates aren’t just for websites. They’re foundational to machine identities—what Analysts now call “non-human identities.” These include service accounts, APIs, and passkeys that power modern IT environments. Every day, organizations rely on certificates to secure both internal and external communications, often without realizing just how pervasive and critical they are.

The Certificate Lifecycle: From Discovery to Revocation

Managing certificates isn’t a one-and-done task. It’s an ongoing lifecycle that includes:

1. Discovery: Identifying all certificates in use, whether self-signed, publicly issued, or from internal CAs.

2. Issuance: Generating certificate signing requests (CSRs), validating ownership, and obtaining certificates from trusted authorities.

3. Renewal: Revalidating and replacing certificates before they expire to maintain trust and security.

4. Revocation: Removing trust from compromised or misused certificates to prevent security breaches.

Each step is essential, and manual processes can be time-consuming and error-prone. As Schnell noted, automation tools are increasingly necessary to keep up with the pace and complexity of modern environments.

The Urgency: New Industry Deadlines and Shorter Certificate Lifespans

One of the most pressing changes facing organizations is the reduction in maximum certificate validity periods. The CA Browser Forum—a consortium of certificate issuers and browser vendors like Google, Apple, and Microsoft—has set new deadlines that will dramatically shorten how long certificates can remain valid:

• Current maximum lifetime: 398 days (just over a year)

• March 15, 2026: Drops to 200 days (about twice a year renewal)

• 2027: Drops to 100 days (about four times a year renewal)

• 2028: Drops to 47 days (about eight times a year renewal)

Why the change? Shorter lifespans limit the window of opportunity for attackers to exploit compromised certificates. If a certificate is stolen, rotating it more frequently reduces the risk and impact of potential breaches.

But these changes also create operational challenges. Organizations that rely on manual processes will struggle to keep up with the accelerated renewal cycles. The risk of outages, compliance failures, and security incidents increases if certificates aren’t managed proactively.

Automation: The Key to Surviving and Thriving

With the clock ticking toward tighter deadlines, automation is no longer a “nice to have”—it’s a necessity. Automated certificate lifecycle management tools can:

• Discover all certificates across the environment, reducing the risk of forgotten or “orphaned” certificates.

• Automate issuance and renewal, minimizing manual effort and human error.

• Streamline revocation, ensuring compromised certificates are quickly removed from trust lists.

• Support crypto agility, enabling rapid updates to cryptographic algorithms as threats evolve.

As Schnell pointed out, automation not only saves time but also reduces the risk of outages. Real-world incidents—like the Spotify outage in 2020, Ericsson’s network failure in 2018, and Starlink’s 2023 disruption—were all traced back to expired or mismanaged certificates. In each case, automation could have prevented costly downtime and reputational damage.

The Quantum Threat: Preparing for a Post-Quantum World

Another driver for CLM modernization is the looming threat of quantum computing. According to Gartner, quantum computers could render traditional cryptography unsafe by 2029—or even sooner, as some experts speculate. While the timeline is uncertain, the risk is real: quantum computers could break widely used encryption algorithms in hours, not centuries.

Organizations must be ready to rotate certificates quickly and adopt new, quantum-resistant algorithms as they become available. This “crypto agility” is only possible with robust automation and lifecycle management processes in place.

Operational Efficiency: More Than Just Security

Beyond compliance and security, automated CLM delivers tangible operational benefits:

• Reduces manual workload: Freeing up IT and security teams to focus on higher-value tasks.

• Minimizes outages: Preventing service disruptions caused by expired certificates.

• Improves developer productivity: Automating CSR generation and certificate deployment streamlines workflows for DevOps and engineering teams.

As Schnell noted, many organizations still track certificates manually—sometimes in spreadsheets. This approach is no longer sustainable in a world of shrinking validity periods and growing complexity.

Looking Ahead: Identity, Security, and the Road to 2029

As digital identity becomes ever more critical, certificate lifecycle management will remain at the heart of security and trust. The changes coming in 2026 and beyond are just the beginning. Organizations that act now—embracing automation, preparing for quantum threats, and partnering with trusted advisors—will be best positioned to thrive in the new era of digital trust.

Conclusion: Take Action Now

The message is clear: the time to act is now. With new deadlines looming, quantum threats on the horizon, and the operational risks of manual processes growing, organizations must modernize their approach to certificate lifecycle management.

The path forward is the clear: educate, automate, and engage. By doing so, you’ll not only meet compliance requirements but also unlock new levels of security, efficiency, and business value.
