7 reasons automation is the solution to 47-day certificate lifespans

In a world where digital certificates require monthly renewal, managing these deadlines across your organization will become nearly impossible. Learn the 7 reasons Sectigo believes automation is the only way forward, and how adopting an automated platform will save your business time, money, and risk in the long run.

1. Avoid costly outages and security breaches

2. Eliminate human error and manual overhead

3. Ensure business continuity even during absences

4. Improve security through frequent validation

5. Achieve crypto-agility and prepare for quantum threats

6. Centralize visibility and control

7. Reduce operational costs and increase efficiency

8. Conclusion: Automation is the only path forward

The digital certificate landscape is undergoing a major transformation. With Apple’s 47-day maximum lifespan for public TLS/SSL certificates ballot now passed, and other browser giants like Google backing the move, organizations must prepare for a future of short-lived certificates. Currently, the maximum certificate lifespan is 398 days.

The first stepdown for this 47-day change is happening in less than a year, on March 15, 2026. When this date rolls around, digital certificates will be required to have, at maximum, 200-day lifespans, requiring renewal 2x per year.

Manual certificate management won’t survive in this new reality. Automation is no longer optional, it’s essential. Below are the 7 key benefits of automating certificate lifecycle management (CLM) in preparation for 47-day certificate lifespans.

Avoid costly outages and security breaches

Expired certificates can cause service outages, trigger browser warnings, and leave systems vulnerable to attack. Under a 47-day lifespan, certificates must be renewed roughly every month, creating enormous pressure on IT teams.

Automation ensures certificates are renewed on time, every time, eliminating the risk of:

Revenue-impacting outages
Data breaches due to expired certificates
Reputational damage from browser warnings like “Your connection is not private”

Eliminate human error and manual overhead

Manual processes are inherently error-prone and time-consuming. They require constant vigilance to avoid missed renewals, misconfigurations, or insecure deployments.

Automated CLM solutions streamline the entire process by:

Issuing, renewing, and revoking certificates automatically
Monitoring certificate status in real-time
Reducing staff workload and reliance on spreadsheets or calendar reminders

Ensure business continuity even during absences

Short certificate lifespans mean no room for delay, even during holidays or staff leave. Automation enables “set it and forget it” functionality that keeps your digital operations secure and uninterrupted.

You’ll no longer have to worry about:

Critical personnel being unavailable during renewal windows
Last-minute scrambles due to human resource constraints
Gaps in coverage from employee turnover

Improve security through frequent validation

Short-lived certificates, when managed automatically, increase security by design. They:

Reduce the window of opportunity for certificate compromise
Force more frequent validation of cryptographic integrity
Support agile response to evolving threats and vulnerabilities

By automating, you gain the security benefits of short certificates without the operational burden.

Achieve crypto-agility and prepare for quantum threats

Short certificate lifespans are a critical enabler of crypto-agility: the ability to quickly update cryptographic algorithms in response to emerging threats, including quantum computing.

Automated CLM supports:

Swift rollout of quantum-resistant algorithms
Seamless certificate replacement across complex environments
Resilience against future cryptographic shifts

Centralize visibility and control

A well-crafted automation platform gives you a complete view of your certificate landscape, including:

All certificates, both internal and public
Expiration timelines
Issuers and usage

This centralized visibility reduces the risk of unknown or rogue certificates, supports compliance efforts, and ensures full control over your cryptographic assets.

Reduce operational costs and increase efficiency

Manual management of certificates eats up valuable time and resources. As certificate volumes increase under a 47-day system, those costs multiply. Automation reduces overhead by:

Streamlining processes across environments
Minimizing downtime and disruptions
Allowing IT teams to focus on strategic priorities

The ROI of automation becomes even clearer when managing hundreds or even thousands of short-lived certificates.

Conclusion: Automation is the only path forward

The shift to 47-day certificates is coming fast. Organizations that fail to automate will face a constant cycle of renewals, risking outages, breaches, and operational chaos.

Sectigo Certificate Manager (SCM) is designed to help organizations manage this transition with confidence. Whether you're managing 10 or 10,000 certificates, automation ensures your infrastructure stays secure, compliant, and resilient.

Start calculating the ROI of adopting SCM in a 47-day world with our 47-Day Impact Calculator, and see how automation pays off before the first certificate expires.
