Join me and the CertKit team on Tuesday, October 6, 2026, at 9:00 AM PDT for a free, live webinar about the upcoming reduction in public TLS certificate lifetimes. Beginning March 15, 2027, the maximum validity period for public TLS certificates will be reduced to 100 days. This change will make manual certificate management increasingly difficult for many organizations.
Automation
Shorter certificate lifetimes require organizations to identify, enroll, deploy, and renew certificates more frequently. Automation can help reduce the administrative effort and the risk of service interruptions caused by expired certificates. This is especially important for public-facing Microsoft workloads such as Internet Information Services (IIS), Remote Desktop Services (RDS), Always On VPN, DirectAccess, and other services that use public TLS certificates.
Visibility
Effective certificate management begins with knowing which certificates exist, where they are installed, and when they expire. Without this visibility, organizations may overlook certificates until they are close to expiration or have already expired.
Internal Certificates
Certificates issued by a private certification authority (CA) aren’t subject to the lifetime restrictions imposed on public TLS certificates. However, they still require inventory, monitoring, and renewal. A consistent approach to managing public and private certificates can help reduce operational overhead.
How CertKit Helps
CertKit is a cloud-based service for managing public and private TLS certificates. During the webinar, we’ll demonstrate how CertKit provides visibility into certificate inventories and expiration dates while automating common lifecycle tasks such as enrollment, deployment, and renewal. We’ll also review recent additions to the service.
