Overview
This guide is also available on my personal blog: https://setupconfigmgr.com/pki-code-signing-certificate-for-third-party-updates-in-microsoft-sccm-scup
In this video guide, we will cover how you can use a code-signing certificate from an Active Directly Certificate Services infrastructure or using a public certificate authority such as DigiCert for signing third-party software updates in Microsoft System Center Configuration Manager (SCCM). Using a trusted PKI based code-signing certificate can be an alternative to using a self-signed certificate.
