Our verdict on Signotaur
Signotaur is a self-hosted code-signing server for development teams that need centralized certificate management and remote signing. It provides a command-line client for automated CI/CD signing while supporting private keys on the server, hardware tokens, HSMs, PFX files, or the Windows Certificate Store. Its signing coverage includes Windows executables and installers, PowerShell scripts, AppX/MSIX, NuGet, VSIX, ClickOnce and VSTO manifests, RDP files, Apple configuration and provisioning profiles, CMS/PKCS#7 files, archives, PDF, and XML documents.
The published plans use one-time pricing. Standard Server costs $199 one time and includes unlimited users, unlimited certificates, and unlimited signings. Enterprise Server costs $399 one time and adds an Internal Certificate Authority, ADCS CA support, and document signing while retaining the same unlimited allowances. Both plans include access to the product’s server-based signing model, and a 14-day trial is available. This structure suits teams that prefer an upfront purchase over recurring plan pricing, with the Enterprise tier aimed at organizations needing internal certificate authority capabilities.
Signotaur fits Windows-centered environments that need certificate assignment, multi-user roles, audit event logging, two-factor authentication, trusted RFC 3161 timestamping, and CI/CD signing through API keys. PKCS#11 support provides a path to hardware-token and HSM-based key protection, while Authenticode, NuGet, VSIX, CMS/PKCS#7, and related formats cover a broad set of development artifacts. The main tradeoff is its Windows-focused, self-hosted approach: teams seeking cloud signing should choose a different product, while teams that want centralized control and a one-time purchase have a clear fit.
