April 21st, 2026
The SSL/TLS landscape is changing rapidly, and one of the most significant updates in years is already set in motion. The CA/Browser Forum has approved a phased reduction in SSL certificate lifespans, ultimately bringing them down to just 47 days by 2029.
This is a fundamental shift in how SSL certificates are managed. What was once an annual task will soon become a continuous process that businesses can no longer afford to ignore.
What Is Changing?
The current maximum SSL certificate lifespan of 398 days is being reduced in stages:
- 2026: Reduced to 200 days
- 2027: Reduced to 100 days
- 2029: Reduced to 47 days
In addition, domain validation reuse periods will shrink significantly, meaning ownership verification must happen more frequently.
These changes are designed to improve security across the internet, but they also introduce new operational challenges.
Why This Change Matters
Shortening certificate lifespans is not arbitrary. It addresses real weaknesses in the current system:
- Limits the damage if a certificate is compromised
- Reduces dependence on unreliable revocation methods
- Forces adoption of modern security practices
- Keeps encryption standards current
The direction is clear: SSL is no longer static. It is becoming dynamic and continuously managed.
The Real Impact on Businesses
For many organizations, this change will require a shift in both mindset and infrastructure.
Manual management will break down
Renewing certificates every 47 days is not sustainable without automation.
Downtime risks increase
Miss a renewal window, and your website may display security warnings or become inaccessible.
Complexity grows quickly
Managing multiple domains, services, and environments becomes more difficult without centralized control.
Support matters more than ever
Not all providers offer the same level of assistance. This is where the right partner becomes critical.
What You Should Be Doing Now
Preparation should start well before these changes are fully implemented.
Adopt automation
Certificate lifecycle management must be automated to avoid errors and downtime.
Audit your environment
Identify all certificates in use across websites, applications, and services.
Upgrade outdated systems
Legacy environments that cannot support automation or modern TLS standards will need attention.
Shift your approach
Think in terms of continuous renewal rather than periodic updates.
