Shorter SSL/TLS Certificate Lifespans: The Future of Digital Security

SSL/TLS (Secure Sockets Layer / Transport Layer Security) certificates are digital certificates. These certificates are used to secure the data by encrypting the data exchanged between a user’s browser and a website server. They protect sensitive information, ensure secure communication and authenticate the website’s identity.

Websites having SSL/TLS certificates use HTTPS instead of HTTP. TLS is basically a modern version of SSL, and it is comparatively more secure than SSL.

What is Lifespans Of SSL/TLS Certificates?

These certificates are issued with a fixed validity period, after that period they must be renewed. Once expired, these certificates become invalid, which leads to browser warning and security risks. Previously, these certificates could even last for a period of 5 years.

Over the time, Lifespans of these certificates are reduced because it improves the security. Major tech giants like Google and Apple are pushing for even shorter validity periods. Currently, they are aiming for 90 Days or even 47 Days Lifespan.

Important: CA/B Forum Approved 47 Days SSL Lifespan by 2029

Overview Of Maximum Lifespan of SSL Certificate Over Time (2012-2029)

As we have already discussed earlier SSL/TLS Certificates had longer validity or lifespan. Before 2012, it was the highest 10 years validity. In 2012, certificate validity reduced to 5 years.

In 2015, the lifespan of these certificates were about 3.25 years. To improve the security the lifespans were reduced.

So, In March 2018, the Certificate Authorities (CAs) mandated to issue these Certificates within a maximum lifespan of 2 years (825 Days).

After One and Half year, In September 2020, giant Web Browser Developers (like Apple, Google, Mozilla) enforced a 1-year validity (398 Days) for these Certificates.

Discussions on further reducing the validity, possibly to 90 days, started gaining traction among Web Browser Developers in 2023.

And now, the industry is shifting towards Automated Certificate Issuance and Renewal to support even shorter lifespans.

Recent Development on Reducing their Lifespan to 47 Days

In a significant move towards enhancing Web Security, Apple propounded a phased reduction in the maximum lifespan for Public SSL/TLS Certificates, aiming to reduce it to 47 days by the year 2028.

Apple introduced this proposal during a recent Certificate Authority/Browser Forum meeting and it’s outlines are:

• In March, 2026: The Maximum Lifespan of the Certificates will be reduced to 200 days.
• In March, 2027: The Lifespan of the Certificates will further be reduced to 100 days.
• In March, 2028: Certificates Lifespan will be finally reduced to 47 days.

Furthermore, this proposal also includes a reduction in the Domain Control Validation (VDC) reuse period to 10 days by September 2027.

CA/Browser Forum Passes Ballot to Reduce SSL/TLS on April 11, 2025

Now finalized: CA/Browser Forum officially approved and released the 47-day certificate lifespan policy by 2029. This marks the formal industry-wide adoption of Apple’s proposal, setting a new standard for public SSL/TLS certificate validity moving forward. Read more on 47-days lifespan by 2029.

The main motive behind this initiative is to boost online security by limiting the duration a compromised certificate can be exploited. Shorter certificate lifespans require more frequent renewals; in doing so, it reduces the window of opportunity for potential attackers.

Impacts of Shorter Lifespans

Reducing the Lifespan of these Certificates will have major impacts, they are as follows:

Enhanced Security:

Reduce Risk of Compromised Certificate – Certificates of shorter lifespan enhance security by restricting the window for exploiting compromised certificates.

More Frequent Updates – Certificates will be renewed more often. It will ensure that sites always use the latest encryption standards.

Less Impact from Key Misuse – If a private key is stolen, it will be invalidated sooner, it will minimize the potential damage.

Operational Challenges:

Increased Administrative Burden – Organizations will face higher administrative challenges because they will have to renew their certificates at increased frequencies which will add complexity to their overall operations.

Vulnerability to Service Instability – Service interruptions could occur due to delayed renewals since more frequent renewals increase the chance that renewals will be overlooked.

Greater Automation Needs – Organisations will have to move away from Manual Certificate Management towards Automated Certificate Renewal solutions because manual processes will become impossible to manage effectively. This will include adopting protocols like the ACME protocol and Cloud-based solutions.

Effect on Various Industries

Enterprises, Businesses, and Web Hosting Companies will be specifically affected. Large enterprises which handle thousands of certificates will not find it feasible to renew them manually every few weeks, and that`s why automation process is must.

Certificate Authorities (CA) will experience more renewals, which will contribute to increased revenue, but they also have to enhance infrastructure to support more renewals. Web Developers and IT Staff will have to implement automated renewal procedures in their systems to ensure smooth operations.

Customer Experience

For regular consumers/users this may improve online security, because it will be compulsory to use latest updated encryption. Though, there is a drawback- if organisations fail to update/renew their certificates frequently on time, users may experience more errors of “Certificate Expired” while trying to visit the website.

Benefits of Certificates with Shorter Lifespans

Reducing SSL/TLS Certificates lifespans to 90 days or even 47 days has several benefits, most of the is related to Security, Reliability, and automation adoption. Here are some benefits of shorter lifespans:

Improved Security:

Restricts Damage from Compromised Certificates– If a Private Key would be leaked or stolen, its utility will be immensely reduced, as the Certificate has shorter lifespans. Attackers have fewer days to take advantage.

Encourages Frequent Cryptographic Upgrades– Encryption standards evolve, and old algorithms become vulnerable. Having shorter lifespans ensures that the websites update their Certificates more frequently, keeping security strong.

Minimizing Manual Errors & Expired Certificates

Eliminates Long-term & Expired Certificates- Many organizations issue Certificates and forget about them until they expire, leading to website outage. Having the Certificates with shorter lifespans forces the websites for better tracking and management.

Encourages Automation– Certificates having shorter lifespans makes manual renewal impractical, pushing Organisations to shift from Manual Certificate Management to Automated Certificate Management, which is more reliable and having less chances of error.

Improving Industry-Wide Security Practices:

Encourages Best Practices– Organizations will need to improve their Certificate Management Process, they have to streamline the process which will lead to stronger security policies.

Reduces Long-Term Risks- As security threats evolve, shorter lifespan Certificates ensures that businesses adapt more quickly to respond to new cybersecurity requirements.

Improved Response to Security Breach/Threat:

Faster Revocation of Certificates– If any vulnerability like Heartbleed or Certificate Authority Compromise occurs, Certificates with shorter lifespans will automatically expire shortly, which will reduce the risk of widespread attacks for a longer period of time.

Less Dependency on Revocation Mechanisms– Present day Revocation Systems are not that reliable. Shorter lifespans of Certificates will reduce the reliance on these Revocation Systems by ensuring that old or expired Certificates become invalid sooner.

How to Prepare for Shorten SSL/TLS Lifespan?

For preparing Shorten 47-Day Lifespan SSS/TLS certificate, it requires proactive planning, automation, and strong certificate management practices.  Let`s see how organisations can adapt effectively:

With the reduction in SSL/TLS certificate lifespans businesses will make a shift toward agile, automated solutions to be able to properly manage the certificates they utilize and make sure that every certificate is always up to date.

Manual management of certificates is no longer possible given the shorter certifications lifetimes; manual management is inefficient, susceptible to human error, and takes more time.

Automated solutions are a must to avoid expired certificates, which create risk and could result in vulnerabilities. You can also take help of PKI Broker or PKI Solution Providers to compare and choose the best automated certificate management tool for your business.

In addition, organizations can start using cloud-based CLM solutions so that organizations can manage all their certificates in one place.

This reduction in administrative overhead will provide a more efficient management solution.

All businesses need to stay aware of the changes around certificate policies, and start preparing, even if the actions seem small, and update their certificate management process to conform.

Getting ahead of the new requirements will ensure compliance is better, and that their security posture is improved.
