So you’ve got the basics down. Your team’s validating inputs, scanning code, and not committing secrets (hopefully). But now comes the hard part—making it stick as your team scales. This chapter is all about going from one-off wins to secure development by default—without turning into a policy-driven buzzword machine.

No, you don’t need an enterprise security maturity model or a 200-slide awareness training. What you need is lightweight, high-impact stuff that helps your team build security muscle over time. Think: practical training that doesn’t insult their intelligence, metrics that track real progress (not just scanner outputs), and a culture where calling out risk doesn’t feel like finger-pointing. We’ll also cover how to scale all this across squads, sprints, and product lines—without losing your sanity or breaking your pipeline.

Let’s kick it off with training—done right. Because no one wants to sit through another “What is XSS?” PowerPoint.
