Who needs a Code Signing Digital ID?

Any software publisher planning to distribute code or content over the Internet or through an extranet risks impersonation and tampering. Code Signing Digital IDs protect against these hazards.
Multisigner offers Digital IDs designed for commercial software developers: companies and other organizations that publish software. This class of Digital ID provides assurance regarding an organization's identity and legitimacy, much like a business license, and is designed to represent the level of assurance provided today by retail channels for software.
