CertKit is a certificate lifecycle management platform that automates SSL/TLS certificate discovery, renewal, and deployment across diverse infrastructure environments. The solution addresses the operational challenges of managing certificates as validity periods shorten from the current 398 days to an anticipated 47-day maximum. Organizations with 10 or more servers face increasing certificate management overhead as manual processes become unsustainable with shorter certificate lifespans. CertKit provides centralized management without creating a single point of failure, automatically discovering existing certificates across infrastructure and handling renewal workflows before expiration events occur. The platform integrates with ACME protocol providers including Let's Encrypt, supports DNS-based validation through secure proxy mechanisms, and deploys renewed certificates to target systems automatically. DevOps engineers, system administrators, and IT operations teams use CertKit to eliminate manual certificate management tasks that consume hours of technical staff time. The platform monitors certificate status across Linux, Windows, Kubernetes, and cloud environments, providing unified visibility into certificate inventory regardless of where certificates are deployed. Unlike command-line tools that require extensive scripting for multi-server environments or enterprise PKI suites that demand specialized expertise, CertKit offers accessible certificate management through both web interface and API access. Key capabilities include: - Automated Discovery: Identifies certificates across infrastructure including forgotten systems, preventing surprise expirations from legacy servers or development environments - Multi-Channel Alerting: Delivers expiration warnings and status updates through email, Slack, Microsoft Teams, and other communication platforms teams actively monitor - DNS Validation Proxy: Handles wildcard certificate validation without requiring full DNS API access, limiting permissions to TXT record modifications only - Deployment Automation: Pushes renewed certificates to target systems automatically, eliminating manual distribution across server farms - Role-Based Access Control: Enables teams to delegate certificate management tasks without exposing critical infrastructure credentials The platform operates outside the critical path, meaning certificate-protected services continue functioning even during CertKit maintenance windows. This architecture provides reliability advantages over distributed renewal scripts that fail silently on individual servers.
