I would like to clarify some details regarding Railway's security protocols and compliance standards. Specifically, I have the following questions:

1. Does Railway provide a transparent overview of its security protocols and compliance measures?

2. Is there any official documentation that outlines Railway's shared responsibility model for security?

3. Where can I find information on how Railway manages potential vulnerabilities or missing security protocols?

4. If I have specific concerns regarding security risks or require further clarification, what is the best channel to contact your security team?
