A PARADIGM SHIFT

FOR CERTIFICATE MANAGEMENT

The maximum validity period for public SSL/TLS certificates will be progressively reduced to 47 days according to the CA/Browser Forum decision. This evolution is not just a technical constraint: it's an opportunity for transformation.

47-day validity

The new maximum duration for public TLS certificates, reducing exposure in case of compromise.

Continuous process

Certificate management becomes a high-frequency process impacting all IT operations.

Automation required

Manual processes become impractical. Automation is now essential.

FREQUENTLY

ASKED
The 47-day validity period improves security by reducing the exposure window if a certificate is compromised. Shorter lifespans also encourage better automation practices and more frequent security updates.
Organizations need automated systems for certificate renewal, deployment, and monitoring. Manual processes become impractical with 47-day certificates, requiring investments in ACME protocols, CI/CD integration, and comprehensive monitoring.
The industry is operating a gradual transition, but it's recommended to start preparation immediately. Early adoption offers competitive advantages and ensures smooth transitions before the standard becomes mandatory.
Key challenges include legacy system compatibility, automation tool selection, monitoring infrastructure setup, and staff training. Our guide provides detailed strategies to systematically address each of these areas.
