The global internet security ecosystem is undergoing another significant change. SSL/TLS certificates — the digital certificates that enable HTTPS encryption on websites — are moving toward much shorter validity periods. This means website owners will need to renew and reissue their certificates more frequently than before.
While this may sound like an inconvenience, the change is part of a broader effort to improve security across the internet. In this article, we explain what has changed, why it is happening, and what businesses should do to stay prepared.
A Brief History of SSL Certificate Validity
SSL certificate validity periods have been gradually reduced over the past decade as part of ongoing improvements to internet security.
Historically:
- Before 2015: Certificates could be issued for up to 5 years
- 2015: Reduced to 3 years
- 2018: Reduced to 2 years
- 2020: Reduced to 398 days (about 13 months)
The industry is now entering another phase of reductions designed to further strengthen web security.
The New SSL Certificate Validity Rules
The rules governing SSL/TLS certificates are set by the CA/Browser Forum, a consortium that includes major browser vendors, certificate authorities, and security experts.
The industry has approved a proposal to gradually shorten SSL certificate lifetimes over the next several years.
| Effective Date | Maximum Certificate Validity |
|---|---|
| March 15, 2026 | 200 days |
| March 15, 2027 | 100 days |
| March 15, 2029 | 47 days |
This means the industry will transition from roughly 13-month certificates today to certificates lasting only about 1.5 months by 2029.
Why SSL Certificates Are Becoming Shorter
There are several reasons behind this shift:
1. Improved Security
Shorter certificate lifetimes reduce the window of risk if a certificate or private key becomes compromised. If a certificate is stolen or misused, it will remain valid for a much shorter time.
2. Reduced Dependence on Revocation Systems
Revocation mechanisms such as CRL and OCSP have historically been inconsistent or slow. Short-lived certificates reduce reliance on these systems and make the overall system more reliable.
3. Encouraging Automation
Frequent renewals encourage organizations to automate certificate management, reducing human error and improving operational reliability.
What This Means for Website Owners
For most website owners, the biggest impact will be the need for more frequent certificate renewals.
Previously:
- A certificate could be issued once per year.
In the near future:
- Certificates may need to be renewed every few months — and eventually every few weeks.
Organizations that rely on manual processes to manage certificates may experience increased operational overhead or risk unexpected certificate expirations that could cause website downtime or security warnings for visitors.
The Importance of Certificate Automation
As certificate lifetimes shrink, automation becomes essential.
Modern certificate management solutions can automatically:
- Request new certificates
- Validate domains
- Install certificates
- Renew certificates before expiration
- Monitor certificate health
Automated systems such as ACME-based workflows (used by many hosting providers and platforms) are becoming the industry standard.
What Businesses Should Do Now
To prepare for the upcoming changes, organizations should:
- Audit existing SSL certificates and track expiration dates.
- Adopt automated renewal systems wherever possible.
- Work with hosting providers or managed service providers that support automatic certificate management.
- Ensure monitoring tools are in place to prevent certificate expiry outages.
