3 - Is the Supplier security policy no longer mandatory?

Answer: Supplier security policy is mandatory only if the results of risk assessments identify that there are unacceptable risks that can be treated by this control, there are legal or contractual requirements that demand the control to be applied, or if the organization has a recorded decision to apply this control. Besides these reasons, an organization is not obligated to implement a supplier security policy.
