What is it like being a people leader in Cybersecurity?

The author of the post works in the Cyber division of a bank as a cyber architect/devsecops for application development teams. They are considering a leadership position, specifically a line manager role, to manage architects and pentesters, aligned with the identify/protect function of the NIST CSF. They are wondering what the role of a people leader in Cyber entails, how it differs from a SWE manager, and if it could open up other tech management roles in the future.
