Keyfactor Signum - 2026 Pricing, Features, Reviews & Alternatives

Keyfactor Signum provides secure code signing as a service, enabling organizations to protect the integrity of their software and CI/CD environments while maintaining development velocity. The platform centralizes the management of code signing certificates, policies, and permissions in a single dashboard, generating and storing private signing keys in a FIPS 140-2 certified hardware security module to ensure these sensitive assets never leave the secure environment. Security teams gain comprehensive visibility and control over code signing operations through granular access controls that can be configured based on specific users, groups, devices, time restrictions, locations, or signing tools.

The solution integrates seamlessly with existing development workflows through lightweight agents for Windows and Linux that are compatible with platform-native signing tools including Microsoft HLK, SignTool, Jarsigner, Cosign, OpenSSL, and Jenkins. This integration approach allows organizations to protect access to private signing keys without disrupting established processes, making secure code signing essentially invisible to developers while maintaining strict security controls. Keyfactor Signum authenticates users and build servers before signing operations, preventing unauthorized access and usage of signing keys through integration with identity providers such as Azure AD and Okta to enable SAML, OAuth, or basic authentication methods.

Keyfactor Signum simplifies compliance requirements through built-in features like key attestation that help organizations meet CA/B forum requirements by verifying keys are properly stored and generated in an HSM. The platform maintains a comprehensive audit trail with an irrefutable log of all signing key access and usage activities, allowing security teams to identify anomalies and simplify audit processes. This centralized approach to code signing security enables organizations to maintain control while supporting decentralized development teams, ensuring that only authorized code is signed with the appropriate keys at the right time and place.
