The main differences between Sectigo/GoGetSSL EV Code Signing and a regular code signing certificate from Sectigo/GoGetSSL are the following two major features:
Extended Validation – offers the highest level of trust since Sectigo verifies the publisher’s authenticity rigorously
Two-factor authentication – the main requirement to store the private key on an external hardware token, provided by mail by Sectigo/GoGetSSL in order to avoid any unauthorized access or malicious usage. Since the private key is stored only on this token, this feature drastically reduces the number of people who can access it, therefore protecting the key from being compromised.
