Choose the right perspective
Match the person's company stage to yours, since building a first security program at a growth-stage company differs from running security at a large public software vendor. For customer trust and compliance questions, favor someone with governance or risk roles in their path; for product and cloud security, favor someone with engineering or operations roles.
