CyberArk Code Sign Manager - Self-Hosted vs SignServer

CyberArk Code Sign Manager - Self-Hosted protects and governs private code signing keys managed by Trust Protection Foundation. Keys can be held in the platform’s Secret Store or on an HSM. Administrators can set restrictions based on purpose, user, and IP address, and configure whether signing requires approvals. Approval flows can have multiple levels, limited-use approvals, and expiration options; approvers receive email notifications to review requests. The system audits key use, and APIs expose event logs and signing statistics. REST APIs can request signing, manage projects and environments, set user rights, inspect logs, and approve or reject requests. Identities and groups can be added through Active Directory or an LDAP provider and assigned roles in signing projects. Clients are available for Windows, Linux, and macOS, with interfaces including CSP/KSP, PKCS#11, GPG, and macOS Keychain; .NET is listed for Windows. GPG private keys remain within Trust Protection Foundation while public keys and private-key stubs synchronize to workstations. Installation is part of a Trust Protection Foundation deployment and requires several listed components, including Certificate Lifecycle and Monitoring, Key Lifecycle and Monitoring, HSM Backend, Authentication Server, Web Console, and Web SDK. Pricing is on request.

SignServer is a server-side platform that centrally manages signing keys and digitally signs code, documents, and timestamps. One installation can serve several signing workflows, including containers, firmware, IoT, and DevOps use cases. It can connect to CI/CD pipelines, firmware build processes, document workflow engines, identity platforms, and other applications through standard interfaces. Community is available as a Docker container, Helm chart, source code, or GitHub release, and is also listed on SourceForge. Its interfaces include SOAP, HTTP, REST, and the SignClient command-line interface, though Community REST lacks some endpoints. Community is released under LGPL V2.1 or later and is intended for learning, testing, and prototyping rather than production. The maker says it lacks production capabilities such as audit, compliance, SLA, high availability, and security features. Enterprise adds professional support with an SLA, security updates, and maintenance. The Community plan is free; the Enterprise Cloud trial is free for 30 days through AWS or Azure marketplaces. The maker recommends Hardware Security Modules for signing-key storage.
