CyberArk Code Sign Manager - Self-Hosted vs Red Hat Trusted Artifact Signer

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.

Red Hat Trusted Artifact Signer (RHTAS) helps organizations sign and verify software artifacts, including container images, binaries, documents, source-code commits, software bills of materials, build artifacts, and AI/ML models. Red Hat describes it as an enterprise deployment of Sigstore. Its client tools include cosign, gitsign, and rekor-cli. Signing can use OpenID Connect identities or self-managed keys held in a third-party key management system. A certificate transparency log records signing events in an immutable ledger that Red Hat says is inaccessible to the public. Deployment guidance covers Red Hat OpenShift Container Platform and Red Hat Enterprise Linux; Amazon EKS is listed as a development preview for RHTAS 1.4. The OpenShift guide requires version 4.16 or later, cluster-admin access, an OIDC provider, and the oc command-line tool. CLI binaries are listed for Windows, macOS, and Linux. Pricing is on request, and a 60-day trial is listed. Signing and verifying AI/ML models with the CLI is marked Technology Preview and is not covered by production SLAs.
