47-Day TLS Readiness Center

The public TLS certificate ecosystem is moving toward shorter certificate lifetimes. Shorter lifetimes reduce long-term exposure from compromised or misissued certificates, but they also increase the operational burden on organizations that still rely on informal renewal processes.

What changes operationally?

Organizations that were comfortable renewing certificates once per year will need to adjust to a more frequent cadence. That means more renewal events, more validation windows, more opportunities for missed deployment locations, and a higher need for repeatable process.

Readiness areas

• Inventory: know every public certificate and where it is deployed.
• Ownership: define technical and business owners for each certificate.
• Renewal workflow: document the steps required for each platform.
• Validation: confirm every deployment works after the change.
• Reporting: provide stakeholders with clear renewal status and risk visibility.

SecureCertOps guidance

Start before the deadline pressure arrives. Build a clean inventory, identify owners, define renewal procedures, test validation steps, and decide where automation makes sense.
