Evertrust Horizon is a comprehensive certificate lifecycle management and governance tool that provides centralized, automated management of digital certificates across multi-PKI environments. The platform supports all major certificate protocols (ACME, EST, SCEP, Microsoft WCCE) and integrates with both enterprise PKIs (ADCS, EJBCA, Nexus) and public certificate authorities (DigiCert, Entrust, GlobalSign). Key features include automated certificate enrollment and renewal, network-wide certificate discovery, compliance monitoring with customizable cryptographic policies, comprehensive audit trails, and native DevOps integrations for Kubernetes, Terraform, and Ansible environments. Horizon addresses the critical challenge of certificate sprawl and manual management that plagues modern enterprises, where certificate-related outages cost organizations millions in downtime and security incidents. Unlike traditional PKI management tools that lock organizations into specific vendors, Horizon's PKI-agnostic approach enables seamless migration between certificate authorities while maintaining unified governance and automation. The platform's emphasis on digital sovereignty helps organizations reduce geopolitical risks associated with over-dependence on foreign certificate authorities
