What tools do you use for centralized management and tracking of endpoint certificates?

For centralized management and monitoring of certificate status at endpoints, the following tools are often used:

• HashiCorp Vault — for secure storage and automatic renewal of certificates.
• Let's Encrypt with Certbot — for automatic obtaining and renewal of SSL certificates.
• Venafi — a specialized platform for managing certificates and keys.
• OpenSSL — for manual certificate verification and management.
• Nagios or Prometheus with appropriate exporters — for monitoring certificate expiration dates and notifications.

The choice depends on the scale of the infrastructure and security requirements.
