Migrating From Manual Certificate Lifecycle Management to a fully automated process

Key Takeaways

• Migrating to automated certificate lifecycle management requires a thorough evaluation of your current certificate posture, leveraging a phased migration roadmap, studying various vendor offerings, avoiding common migration pitfalls, and measuring implementation success.
• The 47-day mandate for the validity reduction of TLS certificates will fully take effect by 2029.
• The three phases of a successful migration are: discovery and inventory, automation, governance, and control
• Post-quantum cryptography migration runs smoother for organizations that automate early and have established crypto agility.

In a world of ever-increasing customer demands, manual processes can hurt your business, especially when it comes to your security infrastructure. Using basic productivity tools such as spreadsheets, storing sensitive information in shared inboxes, and manual tracking of certificates simply have no place in an organization that aims to maintain credibility. Not when TLS certificate renewals happen every six to seven weeks.

Ballot SC-081v3 was passed by the CA/Browser Forum in 2025, which calls for the phased reduction of the validity of public TLS certificates from 398 days to 47 days by the time March 2029 comes around. This movement was endorsed by several major browser companies, including Google, Microsoft, Apple, Mozilla, and many others.

This is no longer a matter of whether to automate, but how to transition from manual certificate management to a fully automated certificate lifecycle management process.

In this article, we will talk about how you can take this industry shift and turn it into a business opportunity instead of just a mad scramble for compliance.

Evaluating your current certificate situation

Before you start making changes to your current certificate lifecycle management process, it’s best to assess your current certificate landscape. You can begin by:

Conducting an overall discovery and audit

You can’t fix what you can’t see. This adage also applies to PKI teams looking to improve their certificate lifecycle management system. On many occasions, there is a large gap between what IT and security teams know about their systems and what’s actually happening across their hybrid and multi-cloud environments. With certificate lifecycle management growing more complex due to the sheer volume of certificates to be managed, it is becoming a primary concern for many organizations, as reported by the Gartner 2025 Buyers’ Guide for PKI and Certificate Lifecycle Management.

Implementing a thorough and continuous discovery process is essential to gaining a comprehensive idea of your current certificate situation. Apart from scanning known public CA accounts and CT log databases, your discovery procedure should uncover shadow certificates (e.g., self-signed certificates) created and used outside of typical IT workflows by developers, and across cloud services, Kubernetes clusters, and IoT devices.

A complete and updated certificate inventory is also key to meeting governance requirements. In 2024, the NIST Cybersecurity Framework 2.0 was launched, which introduces the new “Govern” function. This update serves as a reminder that cybersecurity isn’t just a mere IT concern, but a crucial business matter worthy of executive attention.

Effective CLM smart discovery allows you to scan your entire hybrid and multi-cloud environment to get full visibility into your certificate estate across your organization.

Knowing your certificate baseline

Once you have completed discovery, you can proceed with grouping your certificates by category to better manage and govern your certificates. You can organize them based on:

• Trust Model (private or public PKI)
• Deployment Environment (on-premise or cloud-based)
• Business Priority

Having this categorization will allow you to easily determine which certificates need to comply with the 47-day mandate or fall within your private trust PKI policies.

Constructing a Migration Roadmap

Migration is no simple task. But taking a phased approach can help streamline the process. By breaking down the process into phases, you can build a more realistic plan for migration. Organizations that have a mature certificate lifecycle management system tend to follow this formula:

Phase 1: Discovery and Inventory

This phase is all about establishing visibility, which is foundational for the next phases in your migration roadmap. A lot of companies usually find around five to ten times more certificates when performing a deep automated discovery, underscoring why manual tracking just won’t cut it when working at a scale.

Preferably, you should utilize agentless scanning tools that can pinpoint all the certificates within your environment. Once discovery is ticked off your checklist, you can focus on setting up a centralized inventory for key certificate information such as certificate types, expiration dates, issuing CAs, ownership, etc.

Phase 2: Automation

After completing your inventory, you can now start introducing automation into the process. Start with the public trust TLS certificates, as these are affected by the new mandates from the CA/B forum guidelines. Integrate end-to-end lifecycle automation right up to the application and endpoint so there is no room for manual errors or misconfigurations.

This is also where you should outline your enterprise certificate policies, which may include:

• Signature algorithms
• Approved Certificate Authorities
• Minimum lengths (2048-bit RSA, 256-bit ECC)
• SAN Requirements

Having such policies in place is crucial to avoiding human errors during certificate operations.

Phase 3: Governance and Control

Finally, it’s time to implement PKI policies and governance in place to ensure all teams within the organization are following industry and company-set policies. Standardize certificate provisioning from a central platform across all business units to ensure compliance and auditability.

Enforcing granular Role-Based Access Controls (RBAC) is key to ensuring only the authorized employees in the organization have the ability to manage and automate the lifecycle of certificates.

Work with a platform that offers certificate management self-service with role-based access control.

Migration Timeline and Deliverables

This table shows what an ideal and practical migration timeline would look like. Although durations can differ depending on system requirements, this outline can be a good starting point for security teams.

Phase	Activities	Deliverable(s)
Discovery & Inventory	Agentless scanning of the certificate infrastructure and building of certificate inventory	Centralized certificate inventory
Automation	Integrate automated, end-to-end certificate workflows and outline certificate policies	Automated certificate management system and enterprise certificate policies documentation
Governance & Control	Implement and enforce PKI/ certificate policies	Standardize certificate processes and role-based access control

What to look for in a CLM Platform

When choosing a CLM platform, keep in mind that not all vendor offerings are relevant to your business needs. You must be able to discern which platforms and solutions allow you to meet industry mandates, such as 47-day validity, as well as organizational policies, without adding additional overhead in process or resources.

Talking about non-negotiables, CA-agility cannot be overlooked. This enables organizations to quickly and seamlessly switch between certificate authorities should distrust arise. Companies that are tied to a single-CA service are at risk of having to deal with manual remediation that can take weeks or months. CA-agile platforms can protect you from such a challenge by transferring issuance to an alternative CA promptly.

Common migration mistakes and how to avoid them

Preparedness isn’t enough to guarantee a seamless migration free of any mishaps. Here are some of the common pitfalls that security teams encounter during CLM rollouts and how to avoid them:

Automating everything all at once

When you try to automate your entire certificate estate all at once, you run the risk of not meeting the most immediate deadlines, i.e., the 47-day validity that affects public trust TLS certificates.

To combat this, start by discovering and categorizing your certificates across public and private trust certificates. Implement automation across all of your public trust certificates and build end-to-end integrations that allow you to not only automate certificate issuance and renewals but also automate the provisioning of certificates to the application that needs to consume these certificates.

Neglecting private PKI

A lot of risks associated with public certificates, like outages caused by expired certificates and vulnerabilities exposed by weak algorithms, can also affect private PKI use cases. Even though the 47-day mandate is specific to publicly trusted TLS certificates, this doesn’t mean your internal infrastructure is off the hook from threats. With the explosion of IoT, Agentica AI systems, and other machine identity use cases, ensuring you are actively and effectively managing your private PKI-issued certificates and CAs is equally important.

With enterprise PKI modernization, you have a unique opportunity to enhance your PKI posture. Private certificates can benefit from better visibility, policy adherence, and automation practices.

Leaving Crypto-agility as an afterthought

It’s no secret that post-quantum cryptography is on the horizon. NIST’s 2030 deadline for deprecating traditional encryption algorithms makes it absolutely vital for you to start building crypto-agility as early as now. NIST’s 2025 Crypto-Agility whitepaper includes strategies for modular cryptographic transitions, which also highlights just how small the preparation window is getting.

Luckily, you can prepare for the PQC era with the help of a CLM platform that supports crypto-agility and post-quantum cryptography readiness. This will do more than just support day-to-day operations, but it will also allow your infrastructure to adopt post-quantum algorithms with ease when they become mandatory.

How to measure migration success

The only way to tell if your migration is truly successful is you can present actual improvements to your certificate management system. Here are some of the key performance indicators to help you measure your migration success:

• Renewal Success Rate – should reflect whether your automation workflows are functioning correctly
• Certificate-Related Incidents per Quarter – monitor the number of outages or any events related to certificate issues.
• Manual Interventions per Cycle – track all certificate operations that need human involvement.

The KPIs provide enhanced oversight on your migration’s overall health, from automated workflow reliability to human error reduction. They will also give leadership a glimpse into how certificate management automation drives operational resilience.
