DigiCert ONE is a unified platform that consolidates PKI (Public Key Infrastructure) and DNS management into a single cloud-based service. It is designed to manage digital trust across certificates, software, devices, documents, and machine identities. The platform is organized around several functional modules: - **Certificate Lifecycle (Trust Lifecycle Manager):** Provides visibility across PKI environments, automates certificate renewals, and sends proactive expiration alerts to prevent outages. - **Software Trust (Software Trust Manager):** Handles secure software release pipelines and code signing, with capabilities for scanning code for malware, vulnerabilities, and exposed secrets. - **Device Trust (Device Trust Manager):** Manages IoT device security across the full device lifecycle, from manufacturing to decommissioning. - **Document Trust (Document Trust Manager):** Secures digital documents and transactions with trusted integrations and support for global compliance requirements. - **DNS Trust Manager:** Manages DNS infrastructure with a focus on resilience and availability. - **Public CA (CertCentral):** Issues and manages public TLS/SSL certificates. - **Private CA:** Supports private PKI for internal enterprise use. DigiCert ONE supports policy-driven automation, centralized governance, and self-service certificate management. It is designed to scale and includes support for post-quantum cryptography (PQC) to address emerging cryptographic threats. The platform targets enterprises managing large volumes of machine identities including servers, IoT devices, software, AI agents, and human identities.
