A playbook for the first security hire or the engineering leader who owns security by default: what to do in the first 90 days, how to build a roadmap ranked by business risk, what to buy and what to build, when compliance arrives, and how to report progress leadership can act on.
Service accounts, CI/CD runners, API keys and now AI agents outnumber the people in most organisations, and few of them have an owner. A practical governance model built on inventory, human ownership, least privilege and short-lived credentials that works across clouds and SaaS.
