In this InterSECt 2026 session, learn why the shift to 47-day publicly trusted TLS certificates makes automated certificate lifecycle management essential for preventing outages and controlling operational overhead.
The CA/Browser Forum is reducing the maximum validity period for publicly trusted TLS certificates in phases:
• 200 days beginning March 15, 2026
• 100 days beginning March 15, 2027
• 47 days beginning March 15, 2029
As certificate validity periods shrink, security and IT teams will need to discover, renew, deploy and validate certificates far more frequently. Manual processes built around spreadsheets, calendar reminders and individual certificate owners will become increasingly difficult to scale.
In this video, learn:
• Why publicly trusted TLS certificate validity is shrinking
• What the 47-day certificate milestone means
• How shorter certificate lifecycles increase renewal volume
• Why manual certificate management creates outage risk
• How missed renewals can disrupt applications and services
• Why end-to-end certificate lifecycle automation is essential
• How organizations can begin preparing before the 2029 deadline
Next-Generation Trust Security helps organizations discover certificates, automate renewal and provisioning, and manage certificate lifecycles across enterprise environments.
