CertKit

CertKit provides automated SSL/TLS certificate management software that eliminates the complexity of maintaining certificates across modern infrastructure. Founded by engineers who spent too many hours debugging certificate renewals and watching competent teams waste days on what should be simple tasks, CertKit handles the entire certificate lifecycle—from provisioning to renewal to distribution.

The platform addresses a growing industry challenge: certificate validity periods are shrinking from years to months, with 47-day renewals becoming the standard by 2029. Manual processes that worked for annual renewals break down when certificates need constant attention. CertKit automates this entire workflow, discovering certificates across servers, load balancers, and applications, then managing renewals before expiration becomes critical.

Unlike traditional tools that require extensive scripting or enterprise PKI deployments, CertKit works with existing infrastructure immediately. The software handles certificates for Linux and Windows servers, cloud platforms, Kubernetes clusters, and legacy systems through a single interface. Teams using CertKit eliminate certificate-related outages and reduce management overhead from hours to minutes monthly.

The company serves DevOps teams, system administrators, and IT departments who need reliable certificate management without the complexity of enterprise solutions or the fragility of homegrown scripts. CertKit operates as a distributed system that pushes certificates to infrastructure, ensuring sites continue running even during service maintenance.
