Sensitive Variables

Sensitive variables are a particular type of process variable, used for reserved information such as passwords and login details, which you do not want to make visible to others. Rulex automatically encrypts any variables defined in the Sensitive Variables tab, to reduce security issues in your workflows.

To maintain security levels, when you export a workflow that contains sensitive variables, their values will not be exported. When you consequently import the workflow you will have to be guided through the process of providing values for these sensitive variables.

If you need an ulterior level of security, you can save passwords in an external vault system, and retrieve the values from the vault at runtime.
