How often does your organization renew its secure sockets layer (SSL) certificates? Once a year? That’s about to change. SSL certificate lifetimes are set to become much shorter. By 2029, validity periods will fall from 367 days to just 47—meaning almost eight renewals a year instead of one. Domain control validation (DCV) reuse will also drop from 367 days to 10 by 2029.
CSC’s latest report, “The SSL Landscape,” draws on analysis of more than 802,000 certificates across 2.4 million domains to assess current use trends and management practices. The research found that many organizations still manage certificates in a decentralized way, often relying on spreadsheets and manual reminders, an approach that will be increasingly difficult to maintain as renewal frequency rises. The findings highlight why automation is now essential to prevent expiration outages and improve efficiency
The clock is ticking. Here’s what’s changing—and how to prepare.
The coming shift in SSL certificate validity
Beginning in March 2026, SSL certificate validity will shorten in stages—first to 200 days, then 100, before reaching 47 days by 2029. These changes introduced by the CA Browser Forum and major browsers will apply across all certificate types from domain validation (DV) to extended validation (EV). The transition will place greater operational demand on IT and security teams, requiring updated workflows and processes to manage faster renewal cycles effectively.
CSC’s research found that around three quarters of certificates in use are DV, the fastest type with the lowest verification requirement. While convenient, this preference leaves organizations open to risk, as the same low-cost certificates can be exploited by bad actors to mimic legitimate sites. Preparing early with standardized processes and automation will help organizations stay ahead of the shift and maintain continuity.
Operational impact—why manual SSL tracking will fail
Shorter certificate lifetimes bring real operational challenges. As renewals increase, spreadsheets and calendar reminders become unreliable. Missed dates mean expired certs—bringing down sites and applications, and damaging revenue and reputation.
Fragmentation amplifies the risk. Our research found that nearly 60% of companies use three or more certificate providers. That creates scattered inventory, differing renewal timeframes and notices, and inconsistent processes. Consolidating into one provider simplifies troubleshooting, centralizes notifications, reduces costs, and prepares teams for higher-frequency renewals.
Another complication is that many organizations rely on consumer-grade providers for speed and price. The top three providers in our analysis, Let’s Encrypt, Google®, and Amazon®, accounted for 66% of certificates and most of the DV footprint.
To manage these changes effectively, organizations will need enterprise-class support, guidance, and automation as validity windows shorten.
Automation and certificate life cycle management solutions
Automation is now essential. It scales renewals, enforces consistency, and keeps teams out of fire-drill mode. So what practical steps should organizations take to prepare?
“The SSL Landscape” highlights three key actions for moving from manual to automated operations:
- Standardize and document: Define the end-to-end process so current and future team members follow the same approach, including common pain points and resolutions.
- Educate teams with a single expert partner: A proven provider can help you choose between a large automation platform and lighter-weight API-driven tooling, then guide integration.
- Include everything: Avoid piecemeal efforts that leave gaps. Bring the full workflow into scope so nothing is overlooked during renewal surges.
When implemented effectively, automation lets a company request, receive, and install a certificate as part of a hands-off renewal process—eliminating expiration risk while freeing engineers for higher-value work. Plan early, as integration can take time and may require adjustments to existing systems.
Partnering for smarter certificate management
As renewal cycles shorten, organizations need solutions that combine technology, visibility, and expert support. CSC delivers an enterprise-grade foundation for certificate management, built on proven research, automation, and integration expertise:
- Strong visibility: CSC data shows 40% of enterprises risk SSL outages.
- DCVaaS for streamlined validation: We help organizations dramatically reduce redundant validation steps and speed up certificate issuance with this free service.
- Integrated, centralized management: Our platforms unify certificates, domains, and compliance.
- Flexibility: We provide various solutions to manage certificates from multiple providers.
- Technology plus service expertise: We offer global support combined with APIs, reporting, and automation.
Looking ahead
Shorter lifetimes and 10-day DCV reuse periods mean manual renewal methods will no longer scale. Now is the time to prepare—standardize your processes, work with a trusted partner, and introduce automation before renewal volume rises. These steps will help protect availability, strengthen trust, and ensure teams are ready for the transition ahead.
