CyberArk Code Sign Manager - Self-Hosted vs Notation

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.

Notation is a command-line tool for signing and verifying container images and other artifacts in OCI registries, including software bills of materials. It implements the Notary Project specifications, which are intended to help secure software supply chains. Its signatures can move between OCI registries and be validated in connected, intermittently connected, or disconnected environments without additional server infrastructure. The specifications define signature envelopes using COSE or JWS. Notation can integrate with existing key management systems through a plugin model, with instructions for Azure Key Vault and AWS Signer. Developers and CI/CD pipelines can create signatures and store them alongside signed artifacts. The project provides a quick start for signing and validating a container image. Notation runs on Linux, macOS, and Windows and is free under the Apache 2.0 license. Cloud signing, trusted timestamping, and CI/CD signing are listed capabilities; a certificate is not provided. The specifications repository lists a 2023 security audit, and the project overview describes continuous fuzz testing across three repositories.
